With regard to frequency coverage. You can always build a simple downconverter for a particular area of the microwave spectrum. To obtain true RF level readings you would need a calibrated signal generator operating in the same frequency range and use the comparative level method of level measurement. That's how people used to use older spectrum monitors that had no calibrated amplitude.do you have any suggested reading on this topic? im borrowing a older hp analyzer that tops out at 1GHz and would like to look at 2.4.
If you are interested in viewing the 2.4 GHz ISM band, I can highly recommend the Ubiquiti Airview2. I have a couple of them plus a cheaper Chinese version. These units use dedicated ISM band receivers that provide 300kHz RBW which is sufficient for Wi-Fi, Bluetooth, Wreless cameras, RF ISM eavesdroppers & data links etc. My Airview2 units cost me only GBP30 ($45!) + p&p from the USA. IMHO no techie interested in ISM band stuff should be without one of these or similar units from Metageek .... Wi-Spy (much more expensive). They are relatively cheap, easy to use and designed for the task of monitoring ISM band activity with good sensitivity and level indication.discontinued mac support :-\ whats the cheap chinese version?
Some professionals are very enthousiastic about this one:

The 4.4 GHz version is well withing your budget.

I'm not sure how much I would trust that one, but it does certainly look promising
I am close to ordering signalhound for work. There are several reports on this (mostly by ham radio operators) that are impressive. Consider this is a USB instrument that is achieving -150 dBm sensitivity, which means roughly it is able to resolve ~picovolt level signals. If I get one, I will report back.

Someone here says the max scan rate for the Rigol DSA815 is 10ms. Not exactly sure what that means. Does it mean 10ms to scan the entire 9kz to 1.5ghz range?
QuoteSomeone here says the max scan rate for the Rigol DSA815 is 10ms. Not exactly sure what that means. Does it mean 10ms to scan the entire 9kz to 1.5ghz range?
Yes, the 10ms refers to the scan rate throughout the entire displayed frequency range; so it scans from ~0Hz (displayed amplitude accuracy is just not guarenteed below 9KHz) to1.5GHz, 100 times per second. Of course you can manually decrease the scan rate (for example to 50ms).
Well, here's the response from Rigol on the DSA815:
See attached pdf from Rigol.
Looks pretty decent to me - what do the rest of you think?
Thanks much for the clarifications. So, do you LIKE your DSA815? Is it worth the money ($1,200-$1,500) ?
"I didn't mention that the Peak Hold feature of the analyzers will allow
you to do "N" sweeps capturing the peak value in each "bin". That way
you can see all the hops or transmitters that come up over time."
Well, here's the response from Rigol on the DSA815:
See attached pdf from Rigol.
Looks pretty decent to me - what do the rest of you think?
Since the casting is in very close (intimate) contact with the patient for up to 40 mins every day, and I'm using 24vdc and PWM intensity control, we've got lots of nice sharp square waves with RF ringing all around the patient's neck and near his/her head. So controlling EMF is a big issue. The FDA requires that you keep it under certain levels, for obvious reasons. So the DSA815 looks goos for my purposes, at first glance.
Test gear doesn't just magically arrive for review, I have to somehow acquire it first :-> But as it so happens I am talking to Rigol US about reviewing gear, and that one was on the list. So maybe it will happen.

Looking at the Rigol, it appears very attractive. Certainly very portable, which is a plus. If you get one, I'd be very interested to hear how it works out.
I manufacture prototype medical devices in the field of photo-biostimulation, employing arrays of 820nm infrared LEDs that are mounted in a custom-molded fiberglass casting that fits a particular patient's neck/shoulders. I'm in the medical trials phase presently. I'm treating patients with neurological disorders (like MS and PLS) by irradiating the cervical spine in order to dissolve scar tissue in the regions where the upper motor neurons and the lower motor neurons interact with each other. This takes time (many months) and requires that the patient wear the casting for 10 minutes, 3 or 4 times a day, while the little devils (240 infrared LEDs) happily irradiate their tissues. These are 100ma LEDs arranged in 16 strings of 15 LEDs each.
I would imagine someone of your expertise would have to be able to afford better equipment than a cheap Rigol SA?
Well, I'm just 1 week away from ordering my new Rigol DSA815-TG. I got final approval from my boss (er, I mean, my wife). Of course, I DO wear the pants in the family ('cause she lets me). I plan to order a set of near-field EMC probes (Beehive-Electronics) and also a set of in-line fixed attenuators (JFW Industries) to go along with the instrument.
Pretty excited! I've lusted after a decent SA for several years, but could never justify the expense. Now I can! Thanks Rigol, and thanks Tequipment.net (I'm buying from them next week).

The real question is, does she let you NOT wear pants!

Well, I've gone on the Rigol-USA waiting list, hoping to nab a DSA815-TG in about two weeks when they expect a shipment to arrive from the factory. Right now everyone is sold out of the instrument!

The attached pdf shows the following (@ 750MHz)
RBW Noise
100Hz -94dBm
1K -82dBm
10K -73dBm
1M -54dBm
Allowing for the 10dBm input attenuation, these figures are around 10db lower than expected.
Stated specifications
0 dB RF Attenuation, RBW=VBW=100 Hz, Sample Detector, Trace Average ? 50
1MHz to 1.5GHz <-110 dBm+6 x (f/1GHz) dB, typical -115 dBm
Spec -110dBm + 6 x (.75/1.5 ) = -113dBm
Am I missing something?
Hi
Looking at PDF,Reference level is 0dBm
We have to consider,what if decreasing reference level?
I want to see the measurement result,like SSG -110dBm sinewave
reference level -60dBm
span 10kHz
other setting auto
Noise floor level is not flat anyway,so high frequency's DANL is getting worse,I think.
Soon somebody up the good info,but at the moment,only this site's measurement result 49.5MHz,-129.68dBm is predictable the performance a bit.
http://www.rigol.com/prodserv/DSA800/ (http://www.rigol.com/prodserv/DSA800/)
Looking at this site,I decided to order DSA815-TG.
The setting of measuring 49.5MHz,-129.68dBm is
reference level -80dBm,average 3
span 5kHz
RBW 100Hz
VBW 1Hz
Sweep time 50s
Sweep time 50s is acceptable for me,merely to measure the small sinewave signal for me.
If VBW changes 10Hz,a bit noise floor raise,but it will be -130dBm like that.
Considering the price,I think it is not bad.
This example,Attn 0dB.
But,even if the internal attenuator is set up 10dB,almost noise floor is same,because the ordinary SA's IF amplifier automatically compensate it.
My R3361B can't set up 0dB attenuation actually.only from 10dB.
It is rather safe.
I don't know the difference of noise floor between peak-detector and sample detector,sorry.
I usually only use R3361B's normal detector,I think it is peak detector.
Even though R3361B is old one,but it has quasi-peak detector up to 3.6GHz,but
I am HAM,so I only use as my hobby experiment.
If DSA815-TG is no problem,I will release R3361B.It is too heavy.LOL
Now,I am waiting for DSA815-TG.
Everybody maybe notice that,TG level is only from -20dBm to 0dBm.
Usually TG level of SA is from-50dBm to 0dBm.
My concerns is rather Tracking generator's frequency accuracy,whether we can manually change TG's frequency to just center frequency,or TG's frequency is no problem,once calibrating.
Anyway,when I receive it,I will measure my homebrew 7MHz BPF(BW 100kHz,-6dB,insertion loss 5.5dB).
This BPF is already get the results,so I can check the performance of DSA815-TG.
Hi Dave - that's great news about getting (eventually) a DSA815 for review and teardown!
My DSA815-TG is supposed to ship today from Tequipment.net. They have stock and the item has been pulled from stock for shipping. Its ground - so I should have the unit by Tuesday or Wednesday next week!
Mine will take some time because they have to find a "spare" unit. I guess they can't just take one out of stock and ship it?
Anyway, they have promised that, and a DS4000 sig gen "mid to late May".
Then one of the new 2000 series scopes when they are available.
Dave.
Another nice thing I just wanted to point about about this thing which i hadn't realized at first, is that it includes a 1Hz resolution frequency counter functional up to its full bandwidth of 1.5GHz.
Lock the SA to a GPS reference using the 10MHz input and you have a very accurate frequency counter.
(The condition,when I checked the noise floor)
About demodulation function...
I tried to use it as FM radio with FM antenna,but I can't receive even the strongest signal station here.
Usually I can receive FM radio with R3361B,setting up RBW and VBW etc.
The sensitivity is quite bad,or my function is broken?LOL
Maybe some made-up FM strong modulated signals,like set up by DG4000 series something can be decoded,but as FM radio,it has problem,I think.
If anybody can receive FM station with FM ANT,plz let me know.
I don't know 3.0,but I am using VNWA2.6,and It can measure S21 etc,and of course,
connecting ANT,and it can calculate S11,and other directly put out VSWR etc info.
Now only complete one (not kit) is sold,so a bit expensive,but VNWA is also so educative.
it is worth to get it.
And maybe it is important for you and me...There is no PC software in the original CD.
I expected it has PC software...but no PC software.
I think,we can use Ultra Spectrum,but not sure.
(The condition,when I checked the noise floor)
frequency reference uncertainty = 1e-6 (it's brand new)
You can see the DSA815 is running 23.5 Hz (2.35 ppm) faster than the standard--very close to your observation, and slightly higher than the aging rate though no "factory calibration" specification is available, that I can find.
I also observed a shift when the TG was switched on, however far less that the 150 Hz you recorded, the shift on my instrument was only in the order of 2-3 Hz...

I have no problem picking up FM stations in my area (NS, Canada) with just a plain piece of wire as an antenna. Make sure you set the center frequency to the desired station and adjust the span to 10KHz or whatnot, and also, just in case you forgot, make sure to turn the headohone output on and the volume way up.
I have also noticed it is a bit fussy about USB memory sticks. I have one which is fine in a couple of other instruments and it works in the 815 if inserted while powering up but inserting while powered it causes the 815 to lock up for at least a minute before deciding no stick is present.

Try to write a fresh file system on the stick under Windows. Many USB sticks come pre-formated with a file system that is not exactly right. Typical it is good enough to be recognized by Windows, but other implementations, e.g. in embedded systems, get upset about some missing or deviating details.
I have been able to duplicate what you report, using a cheap Twin-MOS "8-in-1" (I never have figured out what the "8" are?) card reader, and SD cards none of which worked at all even after waiting several minutes. However the same "8-in-1" thingy worked fine with the various CF cards I have accumulated.
All of the dozen or so USB jump drives I have work fine.
I had a somewhat similar problem with a Lecroy 9354L 'scope that had a PCMCIA card slot requiring SRAM. It worked fine with the older SRAM cards having replaceable backup batteries, however it froze when an SRAM card having a rechargeable non-replaceable batteries was inserted. Yet when the rechargeables was inserted before powering up the 'scope it worked fine.
What I found was that the initial +5V current draw of the rechargeable cards was pulling the 'scopes +5V bus low enough to glitch the instrument's microcontroller. Oddly the rechargeable cards worked fine with the older Lecroy 9400 series 'scopes...
I downloaded the UltraSpectrum application (15-day trial) and though I have just played with it a bit I have not yet found anything about it that is worth $260.

A similar setup to UltraView (for their multimeters) I expect. For educational purposes, try setting your clock back after installing the 15-day trial (while it's still active) or more appropriately using a program like RunAsDate to run UltraSpectrum/UltraSigma passing it a year of 1990, and you will have a perpetual license without having to pay $260 for it.
According to this (German)
http://www.mikrocontroller.net/topic/261382#2732635 (http://www.mikrocontroller.net/topic/261382#2732635)
There ought to be a new firmware out
I would contact support.
I would contact support.
I did after creating an account at the http://www.rigol.com (http://www.rigol.com) customer center.
Two days later no response, not even and acknowledgement that I posted a question.
I also mentioned a nasty DSA-815(-TG) bug.
Hook up the TG to the input. Set full span, set the attenuator to 0db and pre-amp on. Set the TG to 0db. Set the sweep time to something long, say 1000 seconds. Turn on the TG and now your analyser is locked up for 1000 seconds. It responds to nothing but the power button and if you have it set to restore the power off settings it will lock up again as soon as you power on.
To regain control remove the input signal and when you turn off the TG you will get one "IF signal out of range" warning message presumably referring to the continuous overload which locked up the analyser.
This seems not to be TG specific. If you set zero span and put in a constant signal at the centre frequency it also locks up beeping at you, sometimes with and sometimes without showing the "IF signal out of range" warning.
Smells like a constant IF overload tries to show a zillion "IF signal out of range" warnings which locks up the UI without managing to show one of them or beep if the TG is on.
The first bug you've described I can confirm. The analyzer is dead during the 1000s and as you described accurately after power-on it comes back to this state.
The second bug I cannot not reproduce. I'm also using firmware 1.05.
He said he cannot break those cal seals ( even though Mike has given a demo on how) and show it. A request from the distributor and a pretty reasonable one. He can find bugs and break it because of that though ;)Shame -- I'm in the market for a new SA and the Rigol was on my list -- but I won't pull the trigger yet -- I want to see what's inside first.

My vote is to omit repeating the tear down of the function generator.
I'd rather the time spent on demonstrating the functionality of the Fgen and how clean its output is.

Thanks for the pictures!
As far as sweep speed is concearned, I do not find it to be too bad at all. Granted, I have no high-end SA's to compare to, but there are certainly no better alternatives in the same price range. If I need to see a precise frequency responce I will lower the RBW, and if I need a fast changing signal, I will increase it. I can usually get all the information I need with a sweep time of (much) less than a second.
I downloaded the Rigol specs in one of their glossy brochures and it does look like the phase noise is going to be quite poor. In one of their videos it shows -87dBc/Hz at 10kHz offset at the lower end of the analyser range.Anyone know what he means by "IP3"??
If you are not worried about close to carrier noise performance then I guess this isn't too much of a limitation but it is probably the noisiest analyser I have ever experienced in this respect. It's so noisy I wonder if the analyser uses the same LO/mix strategy as the higher frequency versions.
In terms of signal sensitivity, the data suggests to me that the analyser noise figure with 0dB attenuation is about 40dB and this is about 15dB deafer than many bench analysers.
The input IP3 appears to be +12dBm with 0dB attenuation and this initially looks good but the NF is high so the 3rd order IMD dynamic range will be several dB worse than a half decent 'regular' analyser.
It does have a preamp to get the NF down to about 20dB but I would expect the input IP3 will suffer a lot with this switched in. Another plot shows the phase noise to be about -105dBc/Hz at 100kHz offset. Good enough for most testing but markedly inferior to a regular analyser.
It would be interesting to see how the IP3 holds up on narrow spans as the glossy brochure shows this test at a 10MHz span. I suspect they chose this wide span to hide the fact the phase noise will spoil the appearance on narrow plots. eg an IMD test on a 20kHz span would look very noisy.
My finger is poised over the "buy" button but I'd still like to find a local source -- rather than direct-importing.I'm in the US and the importer is in a Cleveland Ohio suburb which is only a couple hundred miles away.

I did see that review though it wasn't as complete as I would of liked.
There were a couple members here that either had one or were going to but one. I wonder if they could come forward and post their experiences?
In another forum in a thread that was closed (no idea why) there were a few comments about this scope, but the member who had the most input has his PM's turned off. The main issue to him was phase noise....Anyone know what he means by "IP3"??

So, the more you spend the quieter it be, and the more the amps have dynamic range. So, the question is, is the 815 adequate for your needs?I don't know w/o a hands on test since I don't have numbers to compare properly.
IP2 = SHI on the manualIs that suppose to mean it isn't good? If so, what should I be looking for?
I haven't seen a decent technical review of this analyser yet which is kind of frustrating.Dito. One review was Ok, the other useless.
The areas I would be most concerned about would be the spurious free dynamic range (above DANL) on a basic IP2 and IP3 test across various RBW and attenuator/preamp settings.Good luck finding that. ;)
Also I'd be slightly concerned about internal spurious performance and rejection of external spurious and the quality of the RF attenuators at the front end.
Its very likely videobruce will be making the more extensive review of the 815s RF characteristics!Man, you are really going out on a limb there. ;D
if you aren't too concerned about looking on very narrow spans for modulation issues or 100Hz (120Hz?) PSU ripple on signals or carrier noise then I guess this phase noise issue isn't that relevantI would say probably not. To sum it up, the phase noise problem pretty much concerns the noise floor level, correct?

I see G0HZU point fairly clearly, but here other amateur radio users demonstrate how they can push the noise floor down further or compensate for it.
QuoteI see G0HZU point fairly clearly, but here other amateur radio users demonstrate how they can push the noise floor down further or compensate for it.
Yes but the phase noise issue affects narrow spans the most. The solutions you posted up above are on wider spans.
As a rough rule of thumb the phase noise issue gets less significant by 6dB every time you double the distance from the signal. At a 1kHz offset it is highly significant as you can see in my earlier post.
You can see it spoils the noise floor on a 2kHz span. No amount of messing with the attenuation or preamp will fix this on a 2kHz span. The dynamic range in the 2kHz plot is limited by phase noise and not the settings for the preamp or attenuator.
Hope this helps :)
1. Max input level, there are two figures 20dBm and 30dBm. Supposedly, 20 was what the unit was tested to, 30 is the "damage level" according to the spec sheet. Is this figure based on total levels from all signals within the full bandwidth of the scope, or just the specific range that is currently displayed?
Basically you should consider fitting an external diode based limiter to the front of the analyserAny sources for this, or is this a home brew deal?
The other aspect to this is the Rigol appears to use commercially available parts in the front end....
Some years ago there was an Instek sub-$1000 SA that didn't generate as much interest as the Rigol, due to design limitations.Never was aware of that. It appears to be current. What "design limitations", other than no TG?
What "design limitations", other than no TG?
So can this option be activated without buying Rigols accessory?AFAIK, yes. They are listed separately.
However, be prepared for a large, heavy, and mostly non-portable unit with poor, if any, modern flash drive or usb-based control capability.But, those are deal killers. Don't forget to add, they are power hungry and have the issue of parts availability and service & shipping costs if you can't get it done yourself locally. ;)
Regarding the interior shot of that coupler, are those odd drilling in the four corners for tuning purposes?
from 00.01.05 to 00.01.06 .
Did someone try to do this??
Rigol technician said it's very safe procedure because "boot" will not be touched.
Rufus can you please explain update procedure?
I really hope this is a quality product. $1500 for a SA is unheard of.

Monochrome display, no tracking generator, pretty basic but it seems to work just fine and dandy for what I'm doing.
They originally cost $6K (yeah, right!) but I picked mine up for about $700.
I would have loved a Rigol, with its color LCD, TG and other niceties -- but I do a lot of work on 2.4GHz so the 815 was simply out of the question and the more capable Rigol SAs were too rich for me.
The BK Precision one also has battery operation which is nice for portable use and the LCD is very legible even in full sunlight.
Have you ever seen the RF Explorer from seeed??That model is out of stock, maybe becasue of the proposed tracking generator.

I hear from seeed that they are going to make some kind of tracking generator for the RF Explorer. Perhaps I should wait before I blow huge amounts of $$$. What do you thinK??

I noticed peaks at 900kHz and 10MHz with nothing connected to the DSA815. The 10MHz must be the internal reference, but what could be the 900kHz. LCD display clock? Any thought on this?

Looks like that new ;) 10Hz RBW along with 10Hz VBW bring the noise floor down so low that these glitches appear when you may not normally see them at the designed minimum RBW of 100Hz.
QuoteLooks like that new ;) 10Hz RBW along with 10Hz VBW bring the noise floor down so low that these glitches appear when you may not normally see them at the designed minimum RBW of 100Hz.
I wouldn't call it a glitch necessarily; this is actually a sign that the device is working well. The frequencies mentioned are being used by the DSA815 itself, and the signals are being coupled to the input. Even a simple trace on a PCB acts as an antenna; so while perhaps it may be argued that better shielding should have been used, I'd say that overall this device is performing admirably. And at 10Hz RBW that none of us should have available to us anyhow, I have to say, stop complaining, haha.
I guess in so many words that's what I was saying too. I don't see these at the 100Hz setting and It wasn't designed for 10HZ RBW, so I totally agree. It's also good and fun to speculate their source. I think it's safe to say that we love our 815's :)
Maybe this internal leakage was one of reasons to stop offering 10 Hz RBW as a software option?
Whats this fuss about a few spurs that are -125dBm, any idea how low that is ?. I geuss not.Maybe this internal leakage was one of reasons to stop offering 10 Hz RBW as a software option?
I was wondering the same. It is strange that the spurious can't be seen on 100Hz RBW, since all the signals are more than 10dB above the noise floor, and the noise floor should be 10dB up on 100Hz compared to 10Hz RBW. Makes me think that there is something else going on, like a 2nd or 3rd order intermodulation product.
I think is due to the fact that their DSA1030A has 10Hz RBW standard which is 2 or 3 times as expensive.
I want to check the behavior of a micro strip line in a range of 1GHz - 2GHz
Hi Guys,Well. This is an RF spectrum analyser. The old school analysers I know don't have a log scale for the frequency. And to be quite honest. If you are adjusting an RF-filter you want to have a linear scale, else you might be fooled about the passband shape.
I have already spend 1 day with my DSA8150TG.
Is this only me who miss a logarithmic frequency scale?
I think this is really important, especial for the filter measurements.
I hope I have just missed to find this option. :)

I don't recall that I have ever seen a log freq scale on an RF analyser.
Hi Gents,
There is a PC based software Ultra Spectrum which is suppose to connect to DSA815.
I was not able to install on the Windows 7 64bit.
Probably it adds some extra features like the log frequency axis?
Can someone share his opinion about it?

The DSA815 10 Hz RBW option was initially released to sell in the U.S. for $499, but was discontinued prior to any sales. It is currently planed for incorporation into the up coming DSA830 3 GHz Spectrum Analyzer.
Peter just made his application unavailable.. :-//
I find it a bit odd that the noise floor with no input is so high :-//
Should be 20 db lower... still all pics I've seen shows the traces around the middle of the display.
Maybe we could have someone test and verify that the instrument do meet the specs wrt. noise floor and sensitivity vs. RBW, especillaly with wider filters
Yes, you are right. Big difference of noise floor between them (-53dBm vs -65dBm).
But for the DSA815 it sounds like normal

Who gave you this kind of information? I'm wondering why Rigol should add another 3GHz Spectrum Analyzer? DSA830 + DSA1030 + DSA1030A for me this step makes no sense.

For quite some time now the DSA815 switches on (powers up) immediately when I switch on the power strip. I hasn't done this from the beginning, so I assume I might changed a menu entry but I cannot find such an entry. I even have no idea if there is a menu item to avoid that. I already tried to set it back to factory default but no change.
Is there anything I oversaw? Any hidden menu item to select this behaviour?
Thanks for your help!!
Thought that too, but I could not find an option for "resume on AC power loss".
If nobody knows this behaviour nor can help, I shall send a mail to Rigol to ask about this.
I need some help with my DSA815:Page 2-110.
I am using all my measurement stuff such as my scope and my DSA815 on a switchable power strip.
By this I avoid that they are powered all the time. When switching the power strip to 'ON', all devices should show the heartbeep on the power button, waiting to be pressed to power up the needed device.
Now to the problem:

RF Input Limiter for Spectrum Analyzer (DSA815, or any other)
How to make one, and why you might want to. . .
See PDF attachment:
I just got my DSA-815-TG, calibration dated Oct 2013. I only see 5 options. Opt 2,4,5 are trials and counting down while Opt 3 is not active. As far as I can determine the inactive option is the 10Hz RBW. Were there any other options in earlier manufactures, I have seen 6 options in other posts?
Thanks, any idea why they would not give a trial of the 10hz RBW along with the other trials?Option 3, 10Hz RBW is NOT offered as a Trial because it is not available for purchase. At one time they were considering offering it for US $499, but that idea was squelched quickly. Then someone at Rigol China made a blunder and activated it as a Trial early in 2013 on a limited number of units. Of course people that were familiar with the use of a Spectrum Analyzer (engineers/technicians) immediately wanted it. Oh - So Sorry Charlie!, was the response.

Don't wait until the next firmware update to do it, that may be too late(?).
While performing tests on a home made 1013.3 MHz cavity filter I hit the noise floor before the filters ultimate rejection (should be about 100dB).

Hm... Did you turn preamp on during that measurement?
I've attached the new firmware 00.01.08 (full name 00.01.08.00.03) dated 2013-12-02
Since this forum limits single file size to 1MB I had to split it using 7zip and change file extension. Remove .zip from file name - it should be DSA800(DSP)update_00.01.08.00.03 zip.001 and DSA800(DSP)update_00.01.08.00.03 zip.002
I've successfully upgraded my DSA using Storage->{select "Mobile disk"}->{select file DSA800_UpdateFile.sys}->Sys Update.
All licenses stayed intact (including those added using keygen) and are functioning correctly. The biggest change is additional languages added.

4. Solve the problem marker table and PF don’t display correctly.
when I try to extract files with 7zip, I've got an error. I've made same treatment with other files without any error, I think there is an error in file 2 uploaded.

Assuming you mean this post: http://www.mikrocontroller.net/topic/323002 (http://www.mikrocontroller.net/topic/323002)
I just tested it, and after pressing the magic button sequence I cannot find any new entries in the System menu. That's with firmware 00.0.1.08.
00.0.1.08 also. Worked for me. A message briefly popped up "Welcome to Maintenance Mode" and there are additional items in the System menu.Redid it, and it indeed works. I'm pretty sure I pressed "Meas" instead of "Meas Setup" in my previous attempts. In addition to the Ph Noise Thingy there's also some logging and calibration info like Ref DAC, Cal DAC and LO DAC.
The Ph Noise Opt item was enabled on my unit.
Ok for me also.And the real solution is that trace state is saved in a State file apparently. I just saved a Setup with 3 traces in it. Two of those frozen (reference traces) and the 3rd running (Clear Write). When I save that Setup, then power cycle + recall that setup, I get the situation you describe. All traces frozen. However if I also save the State before power cycling, and then recall both the Setup & the State then I get back the original situation. With correct measurement setups and the correct traces running.
After the special sequence (touch in x arrangement) :
System -> Service -> Signal Ctrl Ph Noise Opt, and is on by default.
I have a problem, possibly simple or already explained in the post : if I save a setup, and if I recall it after, trace is in "freeze" mode (indicated at left of screen), and if I go in menu "Trace/PF", the "Trace Type" button is in "freeze" state but it's impossible to change it (light gray).
The setup is for EMC test with pass/fail selected (same as described by Dave). More simple setup is in freeze state after recall, but it is possible to change "Trace type" in "Clear Write" for example.
Only solution is then to restart DSA or press "preset" button and redo same setup, but with button. Sure it's simple !
Any idea ?
Edit : found solution. Switch Pass/Fail in "off", then set "Trace type" to "Clear Write" and then set "Pass/Fail" to "on". :palm:
In the Maintenance Mode, the Ref DAC value tweaks the 10 MHz internal clock frequency. There was a Rigol service note about it (since withdrawn from their web site) dated Jan. 30, 2013. I've posted the service note in the Files section of the Yahoo! All Rigol Products group.Sounds interesting. :) Do you happen to have a direct link to that document?

Question:i want to buy rigol dsa815 ...the DSA815 Tracking-Gen is a Hardware Option, or just a Software Option?iI can now get licence codes to enable TG or the only option is to buy the rigol DSA815-TG...Thank youThe tracking generator option is not upgradeable - if you buy it without, you are stuck with it that way. The cost of the TG (about $200 USD) is such that it really does not make sense to buy it without, given the utility it provides.
Apart from "no loss of installed options", any noticable improvements? I think I'd rather hear it from the people here than the randomized Chinglish release notes.I checked out the usual things that I do with it (antenna and feedline characteristics, Ham Radio transmitter performance) and did not notice anything. My less than demanding use of the gear would not lead me to notice much... I did try my trick for checking frequency calibration by looking at WWV directly, and the last calibration that I did a month or so ago is still there and I seem to be within a Hz or so of dead on.
So...you wrote inside DSA again FW 01.08...you don't need every time boot it from USB, right??
K
Tom D,
The release note says "Compatible hardware version V05" and it looks like you have V04.
"Version of Main Board: 00.04"
So I just asked a couple of guys at work to 'human' translate the first line of the 1.09 changelog and it states that a change has been made to prevent hacking. Thus it appears that this version (if the unit already hasn't been riglol'ed) may likely be a scheme to prevent riglol generated licenses being installed.It is very well possible that also a new boot loader is put on the new units that prevent loading FW 1.08 (or older versions).
Presumably new units that ship with 1.09 may be riglol 'proof' - will have to see what happens with new shipped units with the new firmware hit the street... Presumably a downgrade to 1.08 would allow for riglol to work and then upgrade back to 1.09.
Anyhow, just a possible scenario for future owners/purchasers to be aware of.
cheers,
george.
http://peter.dreisiebner.at/rigol-bildschirmkopie-lan/ (http://peter.dreisiebner.at/rigol-bildschirmkopie-lan/)Nice application, clean and portable, no need to load drivers if you want to use it via LAN. Also the direct SCPI command modus is handy.

Now how about a script to run that key on a regular basis (every 14 days)?just use the scheduler which comes with Windows (taskschd.msc).
I know it can be done on startup (or shutdown), but that is overkill.
@PeDre+1
Hello Peter - I have spotted that the waterfall modus is not implemented in latest download - is it possible to make the older download available again that had this waterfall modus for the DSA series ?
Thank you !
gazelle
Never use it.
Can't a startup script be written to only act after a certain number of days that isn't another process running?
That's exactly what the Windows scheduler is for. It's not worth optimizing for a single clearing of registry keys every 15 days.Who said anything about "optimizing"??
Does anyone know how to restore Lost TG Calibration Data, or the procedure for for TG Calibration?how did you enter into this problem ??
This is the result of Error 470/471, Calibration Memory Lost.
Any thoughts or assistance would be greatly appreciated.
Thank you in advance for any information.
Hi Bruce,
Our repair process for spectrum analyzers is in the midst of some changes. Currently repair is done overseas back at he factory. This can extend lead times to 12 weeks or more. We hope to establish domestic repair soon but wont have more detail for another month or so. It's not so much that the repair is complicated it's the calibration. So currently there are three options:
1) We can repair the scope for $250 plus shipping.
2) We can sell you a demo/refurb unit.
3) We can provide a discount on a new purchase.
Best regards,
Steve Huss

It is already impossible to load the 1.08 firmware to a 1.09 machine using the described method of the STORAGE button.
Using the PRESET button at start-up to load the 1.08 is still possible with the 1.02 boot loader.
So if you want to have a fully loaded analyser you need to be quick. I personally like the 10Hz RBW option. And would have paid for this, if it was not hackable....
Unfortunate, the 10Hz RBW is not offered by RIGOL
Note also that Rigol told us how to get into the Service/Maintenance Mode to Calibrate the DSA's internal 10 MHz Frequency Standard (with a PDF document).So would you like to provide a link or a copy of this service literature for everyone that would like one?? :-//
It shows as a .pdf, but it downloads as a .zip that 7Zip can't open.
How about just a .pdf file?

Well, it downloads as a .zip. The extension is getting changed.
I'd suggest something is not configured correctly on your system.Indeed. It might be something like a recently installed 7zip thingy that feels so important that it has hijacked all mime types and file extensions. Not sure though. :-//

Hi everyone, I'd just try booting from a previous version I recently bought a DSA815 with the 00.01.09 firmware version and with the version of boot 00.01.04 and it didn't work to get back to previous version 00.01.08, 00.01.07 and 00.01.06 I try several times each and I always get the message : Failed ...(UpdateFile Error!) I would like to try other firmware version if anyone could provide me with previous .sys file.Did you use the preset button procedure form above?
Thanks
Regards,
Hi Orange,
Yes I use the preset Button then push it three times as mention in the procedure below, but I use a 2Gb USB key ... I'll try with a 1Gb tonight (if I can find it). But I doubt it would solve the problem because I'll already add success with this 2Gb key using the firmware on the is the 00.01.09.007 ... Anyway I'll give it a try tonight and let you know if anything changes.
Thanks for the reply,
Hello ted572,
I confirm that the USB Key size (1Gb, 2Gb,4Gb even 8Gb) doesn't matter, also the format FAT or FAT32 both works if I use the firwmare 00.01.09.07 but it's not working with my unit to downgrade to firmware 00.01.06,00.01.07 or 00.01.08. The unit I buy was already with the firmware version 00.01.09.07. But I think what matters here is more the bootloader version that doesn't allow to downgrade the system (for the moment !!!)
There's still some work to do here I won't give up ;)
I recently (August 2014) bought a new DSA815 TG that came with the 00.01.08 firmware version installed.
Then I applied the "option fix" and all options are activated and work well.

My questions are:
Can I upgrade to firmware 00.01.09 without any problems ?
Or should I rather stay with v 00.01.08 since everything is working perfectly so far?
And what real world benefits can I expect to get from the upgrade to 00.01.09 ?
And most importantly, will the activated options stay activated with the upgrade to 00.01.09 ?
Thanks for any suggestions
Thank you both for the feedback, this gives me some confidence that I can upgrade to FW 00.01.09
I will let you know, how it went.
[
Some users have returned there units to Rigol for repair and upon return found their Options removed, and with FR 00.01.09.007, but fortunately still with BOOT Loader 00.01.03. So they were able to downgrade the FW to reinstall the Options, and then upgrade back to FR .00.01.09. But please don't count on this capability in the future after a Rigol repair!
It won't help those who have got the latest boot loader, only people who have had their units tweaked by Rigol after repair :-(
Thank you both for the feedback, this gives me some confidence that I can upgrade to FW 00.01.09
I will let you know, how it went.
Don't worry at all, it will be fine, and you will be very happy!
7-zip is unable to open that file. What type files are inside that?Plain pdf. No zip whatsoever. I vaguely recall another post where you were having a similar problem. The DSA815 10 MHz adjustment pdf I recall. If that wasn't you, my mistake. If that was you, then maybe possibly the problem might conceivably be at your end. You don't have to take my word for it, but best not blame the rest of the world for any future events involving pdf attachments and "7-zip says no workey".
Why didn't you just attach those the way they are here?? :-//
is there a way to tell from the sealed factory box to determine what firmware and bootloader are in a dsa815? Probably by production date ? if i contact a vendor i want to be abel to buy an "older" unit that does not have a locked bootloader. Anybody have an idea on when the bootloader switch over took place ?I don't think that you can tell by the box, at least not on the one that I got. May be starting at a certain serial number.
The new DSA815 firmware 00.01.12.00.02 works well, retains all installed options, adds features, and fixes.
Here you go (one comment: I already had -30dBm on my TG before, not -20):The new DSA815 firmware 00.01.12.00.02 works well, retains all installed options, adds features, and fixes.
Wall-E..can you share the features/fixes list?
Well, considering that 01.09 increases the TG attenuation to -30dBm, does anyone have a copy of 01.09? I'm still using 01.08 and mine only goes down to -20dBm.

hpux735:
Just so you know, there are plenty of us that had DSA815 FW 1.09 installed that never saw, or had a TG range of -30dBm to 0dBm available. But, have always only seen -20dBm to 0dBm with the whole range of firmware versions.
Contention is that -30dBm to 0dBm can not be had on all of the hardware, etc, versions of the DA815, so therefore it has been assumed that Rigol limited the range to -20dBm to 0dBm so that all version of the DSA815 would be the same (consistent) for the TG output level range.
Just to add, the TG default power level on the unit in question is -20dBm, I have to wind it down to -30dBm.So Howard, do you think it might be related to the key used when hacking the SA? The DSA 832 and DSA 875 allow the value to go down to

The DSA 832 and DSA 875 allow the value to go down to-30 and-40 dBmrespectively, so it is likely available to the DSA 815 if we just knew how to hack it.

EDIT: Both the 832 and 875 go down to -40dBm

what boot-loader version does your machine have ?
Does anyone happen to update to this version and do you know what was added or fixed please.
Good that I can move backwards and forwards between 1.09 and 1.12 if necessary.It would be interesting to compare the two load images to figure out which memory location controls the TG level. Then it could be re-written with the old value (and would then probably need a checksum re-calc...). This might even be a way to hack it to -40dBm like the 832 and 875 units. It would be really cool to get it to be a DSA 832! I wonder if it is the same board and components...
The re-writing of the FRAM time parameter appears to still work under 1.12, but I don't know about the other option of simply enabling the WP pin. ( https://www.eevblog.com/forum/testgear/sniffing-the-rigol's-internal-i2c-bus/msg572507/#msg572507 (https://www.eevblog.com/forum/testgear/sniffing-the-rigol's-internal-i2c-bus/msg572507/#msg572507) )
As expected the TG minimum is -20dBm under 1.12, but if I regress back to 1.09 I can still choose -30dBm on the example hardware I have here.
Ray, for informationI have recently bought a DSA815-TG, main board is v00.07, on FW 1.09 the TG will go down to -30dB, the noise floor looks pretty good too.
update 1.12 with your downloadlink is working well. Altough there seems to be a significant change in the mainboards between rev 00.04 to 00.07 and the newest 00.08:
my noisefloor (full span, conds same as posted from Howardlong) is only by -50 dB !!!
Are there any other guys with a new DSA815 (board rev. 07 or 08) who can tell us the same low noise level?

Hi Gents, this evening i just received the VB1020 kit and the full software key.
I will post some updates later how i find it to work ;)
Just updated the licence key .....
I'm interested to hear about the VB1020. It has been sitting in my cart at tequipment, but I can't bring myself to pull the trigger when the price is so steep and I could probably just buy the minicircuits directional coupler + short the WP pin on the FRAM to keep the demo options.I made one of the VK3DIP return loss bridges, he has several variations that go up to around 3 GHz. The cost is peanuts. Mine is good to 1 GHz and usable to 1.5, I used type 43 binocular cores and RG110 coax. The cores were £2 for 5... I certainly wouldn't shell out for the Rigol RLB kit.
I've been really happy with my minicircuits directional coupler. Just saying. :) also, the math for swr and return loss is trivial.
Hi Gents, this evening i just received the VB1020 kit and the full software key.
My DSA came with FW 1.09 installed, and as soon as It turned-up I installed FW 00.01.02. The Main board is version :00.08 and Boot is :00.01.04. FPGA :00.05
Would someone be kind enough to confirm please that using the private Key & Keygen to make the options permanent on the DSA815-TG is still the current method, and do I have to revert back to FW 1.09 before proceeding?

My DSA came with (and still has) the 1.09 firmware and 1.04 bootloader and none of the key generators have generated successful option codes. I intended to pop the cover and see if I could do any good with my new JTAG thing-a-ma-bob, but haven't done so yet. My understanding (though I have not tried it) is that if you still have demo time left you can enable the write protect on the FRAM and keep the demo time from counting down. I think Howardlong on the forum has posted info on that.
'nkw':
Unfortunately there currently isn't a Riglol keygen that will work for your DSA's Firmware (.01.09/.01.04). So for now you should quickly incorporate one of 'Howardlong's' FRAM modification methods to extend the trial periods (hopefully to never expire). My guess is that you may simply be able to solder U1105 pins 7 and 8 together, as long s you don't need to change the network address, etc. If this doesn't work you can piggyback his PIC on top of U1105 to do it fully. You may want to discus this with him first before jumping inside your DSA. As far as using a JTAG, this may be beyond your skill level. But if not, go for it, as a keygen will be required to get the 10Hz RBW, which is not an available Trial. And 10Hz RBW is very important for most of us to have. The other options you should be able to retain and use as is thanks to 'Howardlong'.
Hi all..
I just got a DSA815-TG and after reading the DS2000 thread until my eyes are red, I'd just like some confirmation please before going ahead with the options process, and if indeed it's still valid on the newer versions of the SA.

Ah ok. Thanks for reply ted, I think I'll get a bit of use out of the SA trials first before attempting the FRAM pin 7/8 short. Am I reading correctly that the shorting of pins 7/8 just stop the time counter or reset it on boot etc?
Reading into the post above am I seeing that JTAG reprogramming is required as well as the keygen for the 10Hz RBW option. Or can the keygen be used on it's own to enable this function?
Many Thanks.
did I read in howards post (or maybee it was somebody else that did the mod also) that lifting pin 7 was NOT needed? and that you could just short the pins I thought I read that someplace? Has anybody done this mod and just shorted 7&8 without lifting pin 7?

Orbiter
Great overall Pics! just what I was wanting to plan my Mod! No doubt where pins 7&8 are now :)
...but the chicken in me came out with this 2 day old machine...
sorry for the noob ??? but the chicken in me came out with this 2 day old machine
The trial clock doesn't stop while running, it just resets when the unit is restarted.
I don't know what happens if you leave it on past the trial time...!
One question what is this TX1000 option? Rf demo kit on my machine it's all greyed out and does not seem to be accessible
Even if something wrong was not yet detected after shorting pins 7 and 8 without lifting pin 7, I'm not sure that it is safe way to go.
Imagine the following situation - you are shorting WP signal to Vcc and damage output buffer of controller that control this pin. Then, some new firmware starting to check if FRAM is writable, and block whole machine if any problems with this... The ones who lifted pin will be able to restore everything to previous state, but onew with fried buffer will be in trouble.
While it is possible that there may have been an via-in-pad, judging from the way the rest of the board is made, it's unlikely.
While it is possible that there may have been an via-in-pad, judging from the way the rest of the board is made, it's unlikely.It is easy to remove all solder from the pad with fine solder braid and see if there any vias. But, really, it is unlikely.
What are "vias" and "via-in-pad"???Connections between tracks on different layers.
not sure if it is my dsa815 or me but i ran into a bit of an issue. My machine has pin 7-8 jumped with pin 7 in place(not lifted) What i was trying to do this morning was set up and test a small filter. I had the machine set to full span,auto scale (just like in a tutorial dave did about lc-pi filter #343 @ about 9min 50s into video) What is happening is when i try to use the normalize function if i hit "store refrence" the machine kinda locks up and wont let me switch the normalize function on or off. if i hit preset and start all over but dont hit store refrence the normalize function will switch on and off but the trace is erratic because the machine dosent seem to be storing the information.
I am wondering if this is because of the jumper, just like we cant change lan settings will the jumper inhibit the way the device can store these refrences? Can anybody with a machine modded like this try and see if what I am explaining so badly happens to them. I watched daves video over and over and did everything exactly as he did. I am running FW version 12
Same on my unit which doesn't need the pins to be tied together - went back to 01.09 and normalise works as it should.
I upgraded mine to 1.12 yesterday :-( does anyone can share the 1.09 .sys file ?
Can I downgrade to 1.09 just by providing the 1.09.sys file through the USB port and perfrom an "update" with this file ?
Does anyone know if downgrad to 1.06 will allow the keygen to work ?
thanks
Isn't there a menu setting that sets what the power up/down functions do??
I don't think there's any need, like sheep we just follow what Dave does.
Baaaaah, baah.
What is the purpose of Storing The Reference Trace? I know what is does, but why would we want to do it when using the Tracking Generator? Why would I care what the trace looked like before Normalization? And you certainly don't need to press 'Stor Ref' before dong a Normalize. I have never done the Store Reference prior to a Normalize after initially seeing what it did. So I wouldn't have even known about this Bug (?) without reading about it here in this thread about the 00.01.12 Firmware glitches. And some people have gone back to 00.01.09 to have this function. Why?
Can someone please tell me what I have been missing by NOT Storing a Reference Trace?
I don't think there's any need, like sheep we just follow what Dave does.

Could it be with 220VAC the issue is there and with 110VAC (US) everything is OK?
Bah
Didn't even see if it supports 220-240
mine is 220 v powered and I was having the same bug, thi is why I downgraded to 1.09
Hello,
I have no problem with switching on and Firmware 1.12, here 230 V.
Have you checked the settings for the power button?

Same here, and that document was the basis of my tests.
TG Power Sweep works for me with firmware .12. Did you connect a coax cable between TG Output and SA Input before selecting the 'Power Sweep' settings?. You should see a ramp up to 10/11dB in 10 or 11 steps (I don't recall if it was 10 or 11).

Yes coax connected.. With settings all exactly the same as shown in the Rigol .pdf, I just get a flat-line at -20dB with both FW 01.012 & FW 01.09. Does your SA have the pin 7/8 jumper mod that keeps the trials alive?

Re. TG Power Sweep: No, I do not have U1105 Pins 7 and 8 connected together, as I have an older DSA818-TG (w/FW .12 now). Maybe that is doing something to your unit. I noticed that Howard's SA, and at least one other with his fix doesn't work either. It will be interesting to see if this is the cause, although I hope not, and it kind of seems unlikely.

Also, I looked at my licenses and it seems like some are missing, like the 10hz RBW. But(!), I still have the ability to go down to 10hz RBW. Is this standard now?
hpux735:
The 10Hz RBW is still an Option in there, although it is not provided as a Trial because they don't sell it for the DSA815. When it is activated it will NOT show up in the Official list like the Trials do. Although once it is activated you will be able to find it listed as Option 0003 with the key code used to activate it in the Sys Info screens.
So, I made an LNA breakout board (based on the Skyworks 67015). I used my DSA815 to measure as much as I could. I know my methodology isn't perfect. I'm interested in opinions for how I could improve my methods. I couldn't get power sweep to work (I was using a zero span). I just saw in ted572's post that he's using 100hz span. I'll try that next time. I don't understand doing power sweep and frequency sweep at the same time... Anyway, here's the video if you're interested:
http://youtu.be/hA-5vE_2gG8 (http://youtu.be/hA-5vE_2gG8)
Yes 'Sweep' is mostly referring to a variation in the Frequency. Maybe a term like , " Power dynamic range" or "Power Linearity range" of DUT is better?
Why are there steps in the plot? are there Changes of internal attenuations ?
As you, this mode seems to have confused many users, and consequently they may feel that Power Sweep is not working in their DSA815-TGs. I believe they are probably all working fine, but due to Rigol not explaining the Power Sweep mode sufficiently (if hardly at all) has left many not understanding it in the least, and as a result seeing it as not functioning.
Edit: If you connect a coax cable between the TG Output and SA Input and set the DSA with the Example Measurement Settings shown here -> https://www.eevblog.com/forum/testgear/spectrum-analyzer-rigol-dsa815/?action=dlattach;attach=134859 (https://www.eevblog.com/forum/testgear/spectrum-analyzer-rigol-dsa815/?action=dlattach;attach=134859) you will see the results of Power Sweep without going thru an Amplifier. The results will show the amplitude steps, and be linear.
I wonder why it skips a one dB step every 5 steps.Its not skipping 1dB, its jumping 2 dB.

You should see the results of Power Sweep with its 1db amplitude steps over a 20dB range. Although 1 or more of the steps may have 2 steps lumped together as a 2dB ramp up (probably a Bug).
You can determine if Power Sweep works in your DSA815-TG by connecting a coax cable between the DSA815-TG's 'TG Output' and 'SA Input', and then selecting the following settings:
Preset (Green key), FREQ: 750MHz (the Test Frequency), SPAN: 100Hz, RBW: 100Hz (Required if 10Hz RBW Option is installed), TG: On, TG Level: -20dB, Power Range: 20dB, Power Sweep: On, AMP: Auto Scale, Scale/Div: 2dB, Ref Level: -1dB (or A/R).

It is interesting that the only other people here I know of that have reported Power Sweep not working is 'obiter' and 'N8AUM'. There is one thing in common between the three of you, which is the U1105 modification. Is there any chance that connecting pins 7 and 8 of U1105 could have effected this function? Although it seems unlikely to me. Anyway at this time it would to nice to hear from others having this issue that have NOT touched U1105 in their DSA815-TG. I'm very sorry for suggesting this could even be a possibility, and I truly hope that it is not.

The Video shows the power drops? Does the output turn completely Off when the Ref Level was set?

I don't understand how a VNA can be used as a substitute for Power Sweep to measure an Amplifier's Linearity?

FWIW, my unit doesn't have pins 7 & 8 connected, so the FRAM is writeable, but it does have the slightly more advanced fix that resets the eight FRAM time bytes on power up.
However, I agree that we need some further evidence from the non-tamperers!
It's not a big deal for me, I have a VNA for measuring this stuff anyway, but it would be good to get to the bottom of this.
I don't understand how a VNA can be used as a substitute for Power Sweep to measure an Amplifier's Linearity?
Yes, I hope we get a resolution to why a few DSA's don't work with Power Sweep. Certainly your U1105 jumper 7/8 fix is very handy to keep the Trial Options active for new DSA815 owners, so I hope that there is no issue there with it. And it seem unlikely.
Have you tried using UltraSigma to send SCPI Reset commands (such as Factory, etc) to the DSA to see if that may clear something up. Its easy to do and the commands are listed in the DSA800 Programing Guide. Or also using the new Sanitation mode in the unit. I recall getting into Power Sweep initially seemed a little flaky to me(?), and now it has been working solid for me. Did I clean something up playing with the Power On issue when applying AC power to the unit, or just zero in on the commands/sequence to use it reliably(?).
Edit with a Question: What does FWIW stand for? It must be something like FYI, IMHO(?). I have been wondering about this for some time now. When I first saw it I assumed you had a random finger/keyboard coordination glitch. 2nd edit one minute later: Never mind, I just figured it out. For Whatever It's Worth
Oh Wow, when you said your VNA, I never imagined that you had one of these jewels. At home I have just used a RF Signal Generator and a Tek 496 Spectrum Analyzer to test Amplifier Linearity. At work I used Spectrum Analyzers with Power Sweep, actually they were Network Analyzers.I don't understand how a VNA can be used as a substitute for Power Sweep to measure an Amplifier's Linearity?

It was interesting to see that the HP Power ramp test was at a fixed (user) Frequency.
and the suggestion to use the frequency of a Frequency Sweep 1db drop point.
Where as the Rigol changes both frequency and power level at the same time.
The HP8753 is able to vary the power level continuously, But the Rigol changes the power level in 1db steps (mostly :D)
@Howard did you check when the output power drops off during your TG setup?
From your video it looks like the 'Ref level' change, or the video Editing?
So I noticed if you set the scale to .1db/div and sweep is normalized it slowly starts dropping. The picture shows about -.04db drop after 10 minutes. Its been about an hr now and it dropped to -.07db. Will let it run over night and see what happens. Also every couple of sweeps I get a blip than goes away, I think its something with internal clock and sweep timing ? Anybody working on a new keygen for the ones that have the 1.04 bootloader? I sure miss the 10Hz RBW !
It is interesting that the only other people here I know of that have reported Power Sweep not working is 'obiter' and 'N8AUM'. There is one thing in common between the three of you, which is the U1105 modification. Is there any chance that connecting pins 7 and 8 of U1105 could have effected this function? Although it seems unlikely to me. Anyway at this time it would to nice to hear from others having this issue that have NOT touched U1105 in their DSA815-TG. I'm very sorry for suggesting this could even be a possibility, and I truly hope that it is not.
My 815 is a virgin, no mods. It came with 1.09 firmware. I tried with 1.12 with same results. Unfortunately it also came with 1.04 bootloader so am not able to try it with older firmware. I spoke with Rigol and they will exchange unit for a new one once they come in. Because of the strike out west might be a while before new stock comes in.
This is great news! It is nice that you looked into it with Rigol. . . So hopefully soon everyone should be able to use Power Sweep.It is interesting that the only other people here I know of that have reported Power Sweep not working is . . . .
I have an untouched 815TG with firmware 1.09 and boot 1.04 and I have the exact same problem. However, I could not believe that this is a faulty unit and contacted Rigol. I got a response today and confirmation from Rigol that they just found out about this DSA issue. Rigol confirmed that this is a firmware bug with units that contain the newest version of hardware. They further informed me that this would be high priority and is expected to be corrected soon, whatever that means as the issue I brought up months ago with the MSO2k Logic Analyzer section (see other thread) isn't fixed so far.
Thus, the hardware must have been improved to result in that lower noise level as my response curve with an unplugged input looks very similar to that of HowardLong's unit as shown earlier in this thread..
Was that a recent information by Rigol? As stated above, they seem to have found out that it is a firmware bug.
atx
I've looked but have not found a firm answer to several questions
Does the keygen work with the V1.09 or greater of the DSA815?
If it does work should I buy a DSA815 or DSA815-TG? I look like the keys add the TG so I figure I so not need the -TG version
Thank you
So to make sure I understand, the mod to U1105 will work with FW 00.01.12 by shorting the # 7 and 8 pins on U1105 and that the pins DO NOT have to be lifted from the board. Is that correct?
Thanks!

Hi Gents, this evening i just received the VB1020 kit and the full software key.
Firetank:
Congratulations on you new DSA815-TG. I'm sure you will enjoy it very much. Although I want to to caution you that Rigol has been having problems with their 'expensive' VB1020 VSWR Bridge for the last couple of years. And as a result they have lowered the specifications a couple of time since it was initially released for production. I included a plot of one I tested for a friend in 2013, but please note that they have since reduced the Return Loss Specification to 20dB typical and 15dB minimum. So if you measure your new unit I expect that it could possibly be worse than my test results were.
I have included some links for Return Loss Bridges that are available. You can also use a Mini-Circuits Directional Coupler (although what you get will be what you will have). You may be happier using a Return Loss Loss Bridge (that can be adjusted and tweaked at least a little A/R), and there are several available at reasonable cost ($70 to $150 is reasonable). And then you may want something even better(?). All of the units I referenced I think are probably at least as good as the VB1020 (yes, I believe even the cheapest). I would recommend returning your VB1020 for full refund, and by the way you have the VSWR Key, so that will remain on your DSA. Tell them that the performance is way too low for your use of a RLB, and you will get your full refund. The VB10220 is a nice clean package, but it doesn't work very well for its intended purpose.
What should a RLB have for a minimum Return Loss (with the UUT port terminated with an excellent 50 ohm termination)? Ideally 30dB minimum for general hobbyist measurements, 35dB is preferred, and 45dB minimum for laboratory type measurements. The amount of error, either to the worst, or 'incorrectly' to the better, can be very significant even with a Return Loss Spec. of 30dB. You may want to to do a little research about RLB's to understand and appreciate this.

This is probably a Best choice: http://www.amtronix.com/rlb.htm (http://www.amtronix.com/rlb.htm) Note that it needs a reference '50 Ohm Termination', and one to check its Return Loss* capability (* you will need this with any RLB you buy, or make).
Edit by Ted572: Added the following information. 1/10/2015: Added Mini-Circuits ZFDC-20-4 Return Loss Data.
Explore all of the available RLB options: Search eBay, Google, etc yourself. Do you want to buy or make yourself, and most important what capability suites your primary interest?
Recommended 50 Ohm Termination: Mini Circuits (MCL) model KARN-50-18+, N male connector, 2 Watts, DC to 18GHz, $14 each (brand new). http://www.minicircuits.com/pdfs/KARN-50-18+.pdf (http://www.minicircuits.com/pdfs/KARN-50-18+.pdf) This is an excellent 50 Ohm Termination. You can spend up to ten times more money from other sources, but I don't think you will get any better quality than what this unit has. If you are going to build your own RLB, then I suggest getting at least two (2). One for the reference termination, and one to use for checking (calibration) for your available Return Loss. You can see a KARN-50-18+ on the back side of my RLB (50 Ohm REF).
As to the power sweep issue. My SA arrived this morning and one of the first things I did was confirm...
He assigned me a case number and stated he would keep me informed. I trust this will be helpful to those interested,
Re. Post 567, 568, and 569: The Key here is that name removed at Rigol (email removed) is UNAWARE, was UNAWARE 3 months ago, will still be UNAWARE 3 months from now, and is Fully Incompetent. Ask him about any of the Rigol equipment and you will find out that he's not that familiar with it, or Simply UNAWARE. Rigol has enough problems with their firmware booming out years after product release, and them they have guys like name removed in Product Support. What are they thinking? They essentially have very nice affordable products and then they screw it all up with Firmware issues and a UNAWARE Product Support Specialist.
... is NOT functioning..
... is NOT functioning..
I give them 40 days to fix it. If there will be not a new FW, I will never buy a Rigol again.
A pissed off customer which thinks never go cheap again.
Please be kind and take this as a legitimate question/concern. Rigol has a 3 year warranty, which is void if you make any mods, such as the mod to "stop the clock" on trial keys. If, within 3 years, the device breaks, what do you do???
I understand the advantages of making the mod, but am trying to decide if the features gained are worth the risk of having a device that is no longer under warranty.
Has anybody tried using a block down-converter to throw Wi-Fi Freqs into the freq range of the 815 so they can be monitored?
If so, any recommendations on hardware? I understand that it won't be frequency accurate nor the cleanest way to do it, and there will be the frequency conversion issues, noise, measurements would be uncalibrated etc etc... This is mainly to point antennas etc.
Thanks!
1. Can I safely upgrade to v1.09 or v1.12? and will all my unlocked options still be available?
2. What version should I upgrade too?, from the rigol website I can only get the v1.12?
3. If I want to have the v1.09 where to get it?
4. Is there any website I can download older versions? to revert back?
Hi all,
Just found this great forum and this topic about the 815.
Maybe this has been passed many times, but I have some questions about the firmware.
And I want to absolutely be sure I am having it all understood right.
I was reading about the v1.09 and the v1.12 firmware.
My DSA has the v1.07 firmware with the v1.03 bootloader.
All features unlocked "forever"

Is the firmware V 1.12 posted anywhere? I've requested it from Rigol twice now with no response from them.
Ken
OK, I think I know the answer to this anyway, but would like it confirmed by anyone much wiser than I.
I have a DSA815-TG with the following spec:
Serial: DSA8A1622xxxxx
Main Board Version: 00.07
Version of Radio Frequency Board FPGA: 0.05
Version of Digital Board FPGA: 0.04
Version of Firmware: 00.01.09
Version of Boot: 00.01.04
My question is thus:
1. Is this at all downgradable to what ever version I can unlock the features on (00.01.07 or 00.01.08)?
2. If so does anyone have the relevant Firmware anywhere?
Heres being hopeful.....
James
Hi,
I have found an alternative method for downgrading the firmware, my boot loader is version 00.02, so it may not work for you, but worth a go.
.....
I used this to downgrade from V1.12 to V1.06 on my unit.
From the latest users manual "Do Not Operate in an Explosive Atmosphere"
well damn, kind of takes the fun out of it !
Has any genius found a way for the V1.04 boot loader to be changed to V1.02? This would resolve a lot of people's issues. I am lucky my unit uses V1.02 boot loader.
Dick
I have a question about a Return Loss Bridge result. ...
A question about the Tekbox TBPS01-TBWA2 probe set, which comes with either 20dB or 40dB wideband amplifier. Which one should I go for? 40dB is more expensive. Would I find the the 20dB amp limiting when using these probes? I have only ever used home-made H and E field probes with the spectrum analyser setting on an oscilloscope.I have the 40dB amplifier, and firmly believe that it is the preferred choice. To track down closer to an EMC source you will be using the narrow aperture H-Field probe and you will often need the amplifier, and the 40 dB is very beneficial. By the way the amplifiers are powered from the DSA815's front panel USB connector (5 VDC). And yes you can conveniently use the amplifier for other applications with the DSA, etc. You will often use the amplifier along with the DSA815's internal preamplifier. If you look at the loss through the probes (see Tekbox EMC manual) you will appreciate why the amplifier is required. I don't even think of it as an option. Although if you are just now learning about Spectrum Analyzers, you may want to postpone the Amplifier for now.
http://www.saelig.com/product/M00154003.htm (http://www.saelig.com/product/M00154003.htm)
Thanks ted, I had already purchased the 20dB amp with the kit just before you posted, too late to change it! Nevermind, I will probably end up buying a 40dB amp if I need one in the future.
Not sure what I will do about the DSA815 options, mine has bootloader 1.04. Thinking I'll take the risk and modify the eeprom pins on the PCB before my time runs out.
Frankly, if Rigol makes it so you can't enable the options, then they basically have made it so there is no reason to chose their SA over a used HP etc..
I can easily find a good used Agilent, or Tek SA that has features like SWR/Vector Analyzer features built-in cheaper than the DS815-TG + a $500 add-on.
Thats fine if what they want, but the hobbiest, and ham radio user market will probably go back to used gear instead. Frankly some of the HP/Agilent gear even performs better to begin with.

I'm actually sitting on the fence, trying to figure out if i shouldn't just sell my DSA815 and go buy a used HP. Measuring phase noise is difficult, it's even harder when the SpecAn only has ~70dB dynamic range due to its own synthesizer. Plus, it's an extra $380 for the GPIB adapter...
What options are on it and how much do you want for it if you decide to sell ?

XFDDesign;
Which Hp were you looking at? Have you considered something new? A Rigol 1030A or a 832 if you have the coin? There is also the Instek 9300 at around $2500 less than the 832 with similar specs.

PS Firmware 00.01.13 may still NOT be available as of today, Apr. 6, 2015 (I haven't seen it yet). Hopefully it will be released soon (?).
Is the options key case sensitive?NO, Option characters are NOT case sensitive.
Are the hyphens necessary? If so, how do you enter them?
Congrats on your new toy !
Judging from your cal date you must have the latest shipment. Can you try the power sweep function to see if they fixed the problem or not and if the RBW will only go down to 100Hz? Also curious how much time is left on on the trails. I had 32hrs remaining on mine before I did the hardware mod.
The article is in Germen. Is there an English ver. available?Almost... it's Dutch :)
Now, who wants to work on hacking the newest version with me?
Received my 815-TG today from tequipment today. Cal was done March 14, 2015 of this year. Rather surprised it wasn't double boxed(my Rigol DS1054Z was).
Main board: 00:08
RF Frequency board FPGA: 00:05

Now, who wants to work on hacking the newest version with me?
English translation of 'Measuring Low level Phase noise using DSA815-TG' in Dutch from 'fqahmad66' in his Reply (Post) #634 above (https://www.eevblog.com/forum/testgear/spectrum-analyzer-rigol-dsa815/msg703754/#msg703754 (https://www.eevblog.com/forum/testgear/spectrum-analyzer-rigol-dsa815/msg703754/#msg703754)). Of course there may be some errors in this document because I do not understand the Dutch language. I used the Goggle language translation tool for this task. Feel free to edit and re-post the PDF yourself, or if you prefer to give me feedback for corrections, I will edit the file and re-post it. In any case I hope this is found to be of value to some users in the group. At least we can appreciate the basics for performing Phase Noise measurements way beyond the capability of the DSA815 by itself.
OK, my FRAM is now in stasis - instead of soldering it I used some bare 30 AWG wire and twisted it around pins 7 and 8. The wire is soft enough it will stretch just slightly when under tension and stay very tight. I verified it is working and will check it now and then just to be 100% sure. Still have 35 + hours left.
So now to the option keys. Here is what I am thinking, if Rigol decided they wanted the DSA815 to actually be secure they will have picked a new private/public key pair that can't be easily reversed. If that is the case then I'd say we're sunk without serious further effort. On the other hand perhaps they just changed the option codes themselves. They did do that with the DP832 after all. At this point I think we can ignore the bootloader version and just focus on the firmware version as whatever changes they made occurred before they updated the bootloader. Either way we need a JTAG dump to even have a shot at figuring it out. I was hoping to get someone to send me a JTAG dump from an older version but no PM's I've sent have been replied to at this point. I don't currently have any JTAG hardware but am willing to buy it and dump my DSA815 but it would be nice to study an older version to see where the keys and option codes are sitting in ram before looking at the new version. I shall now research the best/cheapest JTAG interface to get for the job. I welcome any and all discussion.
Is there any chance someone has the latest firmware available for download somewhere?http://beyondmeasure.rigoltech.com/acton/ct/1579/s-0660-1505/Bct/l-3g32/l-3g32/ct3_0/1?sid=pwnRoPaTQ (http://beyondmeasure.rigoltech.com/acton/ct/1579/s-0660-1505/Bct/l-3g32/l-3g32/ct3_0/1?sid=pwnRoPaTQ)
I've emailed Rigol via their ridiculous "request" form every single day for the past week - no response. Talk about bad service!
1. Can I safely upgrade to v1.09 or v1.12? and will all my unlocked options still be available?
Yes
2. What version should I upgrade too?, from the rigol website I can only get the v1.12?
1.12.002 works pretty
3. If I want to have the v1.09 where to get it?
ask someone
4. Is there any website I can download older versions? to revert back?
nope
The most problems are related to the the newer hw version of the 815 and bootloader 1.04 that will unable to flash older versions of FW.
I absolutly sure that an older bootloader version like 1.2 will enables flashing older firmware with all possibilities they gives free.

See PDF attachment:
Son of a b...! It still has a 50 Ohm termination when 75 Ohm is selected?
Since following this thread for a while, I presume if today I order a New 815 it will arrive with the new firmware which will lock the unit from any clandestine hacks or option enablements.
Thanks for proposal about U1105. I have successfully connect 7,8 pins with resistor 680 Ohm. It's as phoenix bird!

Is that like Darmok and Jalad, at Tanagra?
The Rigol FW page still shows .12 as the latest firmware for the 815.
Anyone have the .13 firmware, as shown in the video above, that fixes the power sweep issue?
Does anyone have Hi-Res photo's of the DSA832 or DSA875's main board?
If not is anyone willing to open it up and gets some really good hi-res photo's of both sides of the PCB?

DSA815 Spectrum Analyzer firmware 00.01.13 is now available from Rigol.
Firmware Release Notes for Version: 00.01.13.00.01, Release Date: 2015-07-13
1. Solve bug where the frequency is 500 MHz and PA on amplitude is greater than 1dB and causing PA off problem. M
2. Make compatible with the digital board for 09 version. E
3. Solve the power sweep bug where the trace is a straight line. M
Edit: Added Firmware Release Notes.
My Dsa has the pins soldered together to keep the trial add ons alive, i would be curious if anybody that has done that mod has tryied the new FW. I dont want to loose my free trials
I have a question about a Return Loss Bridge result. A 50 ohm resistive load shows a loss of 39.41 dB. An antenna shows 44.51 dB at its resonant point. So in a 50 ohm antenna system, how can the antenna show more loss that the 50 ohm resistive load? The feedline to the antenna is about 6 feet of RG-58. The antenna is J-Pole tuned to 145.6 MHz.
The yellow trace is the antenna and the purple trace is the 50 ohm resistor.
Thanks,
Len
So who wants to be the 1st to try the new 00.01.13 firmware ?
* At this time the possibility of a New Generation Riglol Kegen doesn't look very likely for the newer DSA815 Hardware. *

What's is changed exactly? It's a brand new key/license management?
Actually, on board 00.08 and boot 01.04, we can only short U1105 pins 7 and 8, like Gertjan said (https://www.eevblog.com/forum/testgear/spectrum-analyzer-rigol-dsa815/msg703809/#msg703809) Can any other confirm this?
It should work also after installing 1.13 right?
I want to compare the dumps of a DSA815-TG that had the keys created with rigup/riglol to a DSA815-TG that rigup/riglol doesnt work on.
i have a .04 machine with the pins soldered for the trial period. i just updated the FW and let the clock on the trial period run down about a minute or two shut the machine off and the counter reset :phew: so it seemes that the temp fix still works with the latest FWCongratulations on your discovery, and kudos to you for being brave enough to even try it. You are the MAN! I'm sure that there are several grateful users that are thankful to you.
I wish someone much smarter than me would find a non-invasive hack for the new DSA815 firmwares. I applaud all of you that are trying!
I want to compare the dumps of a DSA815-TG that had the keys created with rigup/riglol to a DSA815-TG that rigup/riglol doesnt work on.
That would be interesting. Do you know any specs about what's changed in the hardware to prevent riglol working? I guess it's NOT only a private key matter.
p.s. do you suggest to upgrade to 1.13 or to wait a few more?
And what do you think about the write protect enable trick on the FRAM: theoretically rigol can build an update that checks if the write pin it's soldered or not, for example, writing something during the upgrade and then checking the written value after a restart?
I did read that post before I posted my question.
My question was one of clarity for us.
Has anyone done such a test with a second SA to look at the TG signal alone to see if it in in the TG signal itself or is it a combination of the TG/SA on the 815.
Can you post screen shots showing the TG output of the 815 on the other SA you tested with if you've done this?
I'm curious to see if its purely the TG or the combination of both on the 815
Dears,This equals a snowball's chance in hell. Even adding all parts (=expensive) would result in a non calibrated and thus useless tracking generator.
Yes, Pin-connecting 7+8 works with Main Board 00.08 Boot 00.01.04 and FW 00.01.14.
Does anyone know which components you need for an upgrading to the Tracking Generator option, for analyzers without build-in tracking ?
Every Single DSA815-TG, NOT Just Those With the Newer Hardware (i.e. Main Board .07/8) has a problem with the SA Measured frequency using a Resolution Bandwidth (RBW) greater than 100 Hz or so when the Tracking Generator is turned On.

Edit: Underlined - when the Tracking Generator is turned On
I was going to buy a DSA815-TG next week but now I don't know ... is it still a good buy considering this bug has not been fixed?
Can this bug eventually be fixed in software, or is it really a hardware bug?
Evening, I have been away abroad for few months and had no time for my equipment. May i please ask about the latest 2 software upgrades lately.
My 815 have the 00.01.12 installed, now i received 2 upgrades which are the 00.01.13 and today the 00.01.14.
If i may ask can i do directly the latest from 00.01.12 to 00.01.14 and skip the 00.01.13 ?
What would i gain from this upgrade as fixes or add ons ?
My board version is 00.01.04
Thanks for your assistance and your time gents.

It is difficult to see why these features can't be solved in firmware, although Rigol have apparently previously stated that the 10MHz glitch is hardware related.

When and where did they state this? Do you have a link?
In case it would be an hardware issue, would it mean a new revision of the Rigol DSA815?
Maybe they have already fixed the hardware issue in the mean time in a newer revision?
Is Rigol support in America in the loop on this subject matter already?
According to tests performed by other users, the bug is in the SA WHEN TG is activated. When the TG is OFF the SA works flawless.
So maybe they can fix this in the firmware code for the tracking generator.
will upgrading to ver.0.14 delete the options?
Anyone made any progress on the software hack for the newer DSA815?.. Missing the 10Hz BW! :)
Ray.
@Sandra:
Sandra (Yes, I am a Woman :p )
you kidding - the hell know what this means.
If you have an older one and haven't already I'd go ahead and use riglol and enable everything including the 10hz rbw. but that my opinion. just go here for the web version http://gotroot.ca/rigol/riglol-103d/ (http://gotroot.ca/rigol/riglol-103d/)
I had testet the actually firmware V1.15 from 01.12.2015 for the DSA-815 (TG) and my device response with a continously beeping and an error message "413 intermediate frequency signal out of range." just before the initializing are finished.
The firmweare is released at]http://int.rigol.com/Support/SoftDownload/3] (http://int.rigol.com/Support/SoftDownload/3). I attached my version report of the DSA815-TG, who is about 3 Years old and not often used.
I have downgraded to the V1.14 and the Error Message does not occurs - the Spec weorks proper.
I also had testet the Hardcopy programm Bildschirmkopie x64 from 30.11.15 from Peter Dreisiebner also response very slow on the DSA815tg.
To proove the software, connectivity (eth) and Windows 10 (586.11) i had test them with the the scope DS2202 and that works fast as expected.
I had read about some extensions in the hardcopy part of firmware that maybe responsable for that missfunction.
So beware to use the 1.15 if you could'nt downgrade your SA.

license for sale if anyone is interested.I guess is legitimate to hack the options for personal use, while it is not if you're reselling the hardware hacked. Am I wrong?

Haha - I just discovered a goofey bug. When you select .bmp for the screen print to save to a USB stick, the saved file is "right-side" up. But when you select the saved type to be .jpg, it saves it "upside-down". :wtf:
Edit: .png is OK though ...
do I need to downgrade the FW to something prior to 1.09 and then utilize the keygen?
Here is a dumb question --- if you revert back to FW 1.08 to add the TG - is there some way to still use the TG with later firmware versions? It seems a lot of fixes and enhancements occurred with 1.09 and later.

Rigol firmware available here - http://int.rigol.com/Support/SoftDownload/3 (http://int.rigol.com/Support/SoftDownload/3)Website was not working for me.
Not a lot of changes, thus not worth for installing for most of us. The release note says:
Version 00.01.16.00.03 from 18.05.2016:
1. Added support for new models DSA705 and DSA710.
2. Solve the bug of command “:SENSe:TPOWer:MODE?” returned wrong result
3. (AE 201512000256)Solve logarithmic abscissa save csv data error problem
I did only try the PNG mode - this one is not upside down.
OK, just for you :-* I tried to save a JPG and guess what: still upside down. BMP and PNG is fine as I said.I did only try the PNG mode - this one is not upside down.
I understand that, but they have a bug that's gotta be pretty damn simple to fix, and they don't even touch it? I mean come on, that's just lame. The bug's been there for a long time.
Edit: Price of Rigol's '2FSK-DSA800' Option Activation? Not available at this time.I stumbled upon this link yesterday: http://www.rigol-uk.co.uk/Rigol-SSC-DSA-Signal-Seamless-Capture-p/dsa700-ssc.htm#.V2JGVlWLT0M (http://www.rigol-uk.co.uk/Rigol-SSC-DSA-Signal-Seamless-Capture-p/dsa700-ssc.htm#.V2JGVlWLT0M)
I've been thinking about how to 'convert' or 'mod' the DSA 815-TG ...
A quick follow-up: Fortunately it's possible to downgrade back to 1.16 and the trial licenses reappear. I guess now it's time to save an image of the FRAM contents...
Surprise, surprise! Apparently, the firmware update to 00.01.17.00.04 has enabled the 10Hz RBW option on my DSA815-TG! Though I didn't find this specified anywhere. Either the new firmware must have enabled this or my "messing around" with up- and downgrading several times.
Okay, I just re-checked: If I downgrade to 00.01.16, the minimum RBW is again 100Hz, after the upgrade to 00.01.17 it returns to 10Hz.
So I'm quite surprised why Rigol didn't report this in their changelog, or maybe it's unintentional, a "bug" so to speak ;D. I love these kinds of bugs...
Now it's a hard decision, rather have the trial options or the 10Hz RBW. I guess for me the 10Hz is more valuable since I hardly used the options for anything else than playing around, while I often whished I had better frequency resolution. Lets see, if this "bug" gets eliminated in the next update...or if it's a "si(g)lent" improvement to have a better standing against the competitor 8).
Cheers,
Thomas
So to summarise for 1.04 bootloader versions:
o 1.16 still works with or without any FRAM fiddling;
o 1.17 ignores any previously trial time, and will also erase any trial time if the FRAM isn't write protected;
o If the FRAM is write protected, you can downgrade the firmware back to 1.16 and the trials reappear.

Hello Howardlong:
What happens with FW 00.01.17 and Boot version 00.01.04, if the FRAM is write protected with your PIC piggyback configuration? Will the options be available and be retained? In any case I assume that the 10 kHz RBW will be available now.
Thank you, Ted
I haven't tried yet, before looking I wanted to understand the current known status, can you confirm my precis is reasonable, or have I misunderstood anything?Howardlong:
@danny_isr --
if you install firmware 00.01.17 on a machine with older firmware and still remaining trial time, this trial time will be lost. The FRAM chip contents will be extensively modified
There is new Firmware available for the DSA815: DSA815 Firmware_00.01.17.00.04
To get this you can go to > http://int.rigol.com/Support/SoftDownload/3 (http://int.rigol.com/Support/SoftDownload/3) Then go to > Spectrum Analyzer. Then Download > DSA815 Firmware_00.01.17.00.04
V00.01.17 2016-08-15
-----Added the SSC fuction
-----Cleared the LAN communication trouble
-----Resolve the front panel switch control problem
Yes, it is safe to install, and all options are still there for all the older DSA815's with Boot loader 00.01.02 and .03. Enjoy . . . See my previous post (Reply #784) to see the full System and Firmware Information after doing the FW upgrade.
Edit: I Do Not have the newer version DSA815 that TurboTom (Thomas) describes in his post below (Reply #786). If you have a Newer DSA815 with Boot loader version 00.01.04 then be sure to at least read post's (Reply #) 786, 787, and 790 ( * -> may very well be a potential fix for the newer DSA815s).
FYI - All older DSA815's/TG (with Boot loader 00.01.02, 00.01.04) are all working fine as is with this Firmware upgrade.
Ted572
Are we sure that the hardware is different ? I read the opposite on another discussion group, not specifically related to the Rigol.
Alberto
Alberto -
you've only got to read the specs of the 815 vs. the 832 carefully, especially concerning the weight of the two units. Unfortunately, they are not identical. I think Shahriar also did a teardown of a higher-frequency DSA800 model and if I remember correctly, there were one or two more separate metal RF boxes inside than in the 815.
On the DSA-815, is there a way to capture the frequencies of momentary signals within a given frequency range?
I am trying to capture frequencies in use within a given band and log them and am using Peak Tables and am trying to set a “peak hold” to track frequencies of short-duration ephemeral signals and continuously display or log them, as the peak table displays frequencies of signal it detects but clear off the screen immediately, before I have a chance to record them.
I have been scouring the user manual and various communities and cannot find the answer to the following question:

Also, regarding option trial times. Does the time decrement continuously when the SA is running, or only when an advanced option that uses the trial license iis enabled?
Thanks in advance!
Dear Gertjan,
Thank you very much for help, it works fine.
I think, to get the trial options with bootloader 01.04 and version 16 again, it´s important, that the solder-jumper has been set before the updating to version 17.
Best regards
Oliver
So the noise floor of the Rigol is getting closer to the Siglent?
Initially there was 20 dB difference between both. Now the Siglent is still 10 dB better?
Who is giving the Rigol vs Siglent noise floor verdict based on the screenshots? :)
Hi
attached some pictures from DSA815
As it is very slow i changed sweep speed

Just to clarify, I have an older 1.03 bootloader and currently run 1.06 f/w (on a 0.04 mainboard).
I have all the options opened up fine (thank you wonderful EEVbloggers) and would like to keep them!
Did you soldered anything or just used the riglol crack SW?
If you did not soldered anything on your DSA, with FW1.18 all your options will be still there... but the 10Hz RBW will be per default active an not showing in the list anymore. There will be also a new option SSC-SDA which will be deactive, and it seems nobody hat yet got the way to activate it.
Just look my post here on this page, just scroll 10cm up.

all options still working well.
I have a DSA815 with old Bootverision 01.02. With firmware version 01.07 all licenses with the key generator were entered. I have not used the write protection of the FRAM.
The firmware was updated step by step up to current firmware 01.18.
Now I have entered a trial license for the SSC-DSA option, and then activated the write protection of the FRAM.
After switching on, the trial time is counted down, but after a new start the time starts again with the time of the write protection activated.

Good day All
First I would like to thank all the members here who have dedicated their time to furthering the hackability of the Rigol DSA815-TG.
I just purchased the DSA815-TG and wanted to say that it came with All functions operational as Trial with 35 plus hours out of the box, except for the SSC-DSA option.
I have attached photos of the license screen.
My questions is; since the wanted options are enabled now, should I do the FRAM write mod.?
I see from the above that the mod. does indeed work with the 1.18 firmware, but what about the *new* hardware that this model has?
All ideas and opinions are welcome, as I really want to keep the VSWR option functional.
Thanks
take care, peace

EDIT: added firmware photo.
I had exactly the same issue with mine. Funny thing is: After some time of use (must have been 10 to 20 hours), the original trial licenses magically reactivated themselves with full 35 odd hoursOh! I remember reading your post about this, but seem I forgot about it! :)
I had exactly the same issue with mine. Funny thing is: After some time of use (must have been 10 to 20 hours), the original trial licenses magically reactivated themselves with full 35 odd hours (noticed only some five hours later since a colleague was using the instrument). Before that I tried everything to uninstall the old trial licenses to make the newly provided ones the only and active ones -- without success. I guess all this relates to a new number format in FRAM for the time totalizer Rigol has introduced with f/w 1.17. Anyway, after the trials reappeared, I quickly closed the WP jumper and the trial time is frozen again...I can confirm that the above procedure works. Somebody with this device had the same problem after upgrading to Firmware 1.18. He also got new license codes from Rigol which were not working (same as above). I then told him what Tom wrote. He tried it out and he just reported that, after approximately 18-21 hours runtime (with some short breaks for a restart for checking if it is now working) his licenses suddendly were reanimated.

Thomas
How could you use a KARN-50-18+ to adjust one of these? The minimum return loss for the KARN-50-18+ is 35dB for DC-1MHz according to the Mini Circuits data sheet.

Hello 'orin': Where did you get that a 'KARN-50-18+ is 35dB for DC-1MHz' from?
The Mini Circuits KARN-50-18+ is specified to be typically better than 40 dB Return Loss from DC to 6 GHz. And I have never seen one that didn't have a 50 dB Return Loss up to 1 GHz, and often up to 2 GHz. I know that they are not specified to be this good, but Mini Circuits has always provided these to us with much better performance than they specify. Yes, even by 10 dB better at these lower frequencies. Anyway I'm confident that they will work great for the devices we are concerned with here.
KARN-50-18+ Specification is attached below.
I'm pretty much confused with minimum RBW figures of DSA815. On Rigolna.com, the minimum RBW is mentioned at 10Hz, on rigol.eu and int.rigol.com, it has been mentioned at 100Hz, on all online manuals, it's 10Hz, but in all reviews people saying it's 100Hz.
Recently i bought a new unit and it goes down to 10Hz, but in spans more than 150KHz, it shows UNCAL sign when I reduce the RBW to less than 30Hz.
Same confusion applies for DANL and phase noise. What's going on with Rigol?!?
Hi all!Hi,
I guess this is a stupid question.
I have a DSA 815TG with boot version 00.01.04 with firmware 00.01.09. and no time left on the trial options.
If i upgrade to a newer firmware will the trial options timer be reset?

Good day everyone,Hello Raj: I understand from reading your post that you installed the Rigol Options with firmware 00.01.18 installed.
My DSA-815TG runs with the current Firmware 1.18 under Hardware 0.04 and boot loader 1.03. Generating keys with RIGLOL and activating the same under 1.18 works perfectly fine, the 10Hz RBW option was accepted but obviously has no effect as this option is available per default these days. All other options except for the last one are active as expected.

Although this is the first time that I have heard of anyone being able to use the Riglol Keygenerator for installing Option License Codes on DSA815 firmware 00.01.09 and above. Are you sure that you installed your options with firmware (FW) version 00.01.18?
History: When Rigol introduced firmware 00.01.09 it was no longer possible to use the the Riglol Keygenerator to activate the Options. We had to revert back to FW 00.01.08, or earlier to get the Options activated. And as long as we had BootLoader .02, or .03 we could do this with the 'Boot Method'. Although those with BootLoader .04 could not because this BootLoader did not allow the FW Boot Method to work any longer. It is the newer FW (.09 and later) that prevents the Keygenerator from working, and it is BootLoader .04 that prevents using the FW Boot Methode from working any longer.
If this is correct, then it may then be possible for users with the new Main Board Hardware (V. 7 and above) to also install the Options. This would be fantastic news for them, and these users should at least give it a try to see if it works for them!

Just out of curiosity, could you downgrade ti the earlier version and recover the trial licenses?
Just out of curiosity, could you downgrade ti the earlier version and recover the trial licenses?
granted, however the DSA815 support boot from USB and the blackfin supports uart boot. so if we have the boot code in LDR format and put that on a USB drive or load via uart to get 1.03 in then could we not backload FW1.0x then?Hi Sandra: The Blackfin's interface capability can be limited/overridden by the instructions from the Boot Loader. Or purposely left out by the hardware designer for expediency because it wasn't required for the task. I think that the current .04 Boot Loader most likely preempts doing this, so I think someone will have to directly force a .03 Boot Loader (or equivalent) in place of the .04.
I don't have any vested interest here, because I have the original hardware with all of the permanent Options (so far anyway). If I had the newer unit I would be charging into this relentlessly with a DSA815 open on my bench, to try to at least understand high level system architecture used. I did this for my units Front End, LOs, Mixers, and IFs through to the DSP. https://www.eevblog.com/forum/testgear/spectrum-analyzer-rigol-dsa815/msg1059060/#msg1059060 (https://www.eevblog.com/forum/testgear/spectrum-analyzer-rigol-dsa815/msg1059060/#msg1059060)
You may want to consider sketching out your units digital control logic, as it may help shed more light on all this. Most of the ICs have vendor P/Ns, and some have SMT Codes. Doing this with Peter's info may help pull it together.
EOT and Cheers, Ted

I recently got a used DSA815-TG and would like to update the firmware on it. I have some questions, maybe someone here can help me out.
The unit seems to be quite old and has the following versions:
Main Board: 00.04
RF Board: 00.05
Digital Board: 00.04
Firmware: 00.01.08
Boot: 00.01.02
Now i downloaded the V00.01.18 update from the Rigol site, but in the installation instructions in the archive say:QuoteApplicable models and component versions:

Does that mean, that i can't update my unit with this update? Are there other updates available for older units? The problem with the current firmware is, that the remote-commands seem to be not fully implemented, so the automation software i would like to use does not work.
Another question - The device has options enabled (keygen) - Will these options be lost, should the update be possible?
thanks,
Sebastian
I was looking at that but way out of my price range. I just purchased the SIGLENT SSA 3032X, already found a bug LOLPlease report it here:
Hi,Don't worry, mine is doing exactly the same :palm:....
Got a strange problem with the DSA815 and would like to see if anyone else is observing it.
Bought it recently about 6 months ago.
When using the DSA815-TG to get a spectrum output from a HF transmitter, seen a strange spurious signal in the area of 14.3 MHz.
Specifically, when a signal is fed to the instrument, in the area around 14.3 MHz eg 14.25 MHz or 14.35 MHz, appart from the original signal there is also displayed another signal (mixing product?), for that see attached images 501/2/3/5/6/7. When feeding the instrument with a signal at exactly 14.3 MHz, then the observed phase noise gets beyond the instrument's advertized limits, for that see the attached image 504.png
To verify the problem, I replaced the HF transmitter with a lab signal generator, the DG1022Z.
Seen the exact problem again.
The screenshots attached are from that setup, DG1022Z transmitting into DSA815-TG and the problem is still there so it was not the HF transmitter.
Has anyone else seen this or is it just my unit?.

Don't worry, mine is doing exactly the same :palm:....
It is about 3 years old and the MB version is 00.04
Probably an issue with all DSA815 systems.
Yes, a am aware that the unit can save to a thumb drive, I even put a button to do that on the first form.I say LET IT RIP,we need more people like you that don't mind sharing their knowledge !
Thanks for the discouragement in the pursuit of knowledge and the sharing with others. :palm:
I followed the link you provided, I am not good at German, and Google failed to translate. Maybe I'll try again later.
There is now a new RSA5000 Series of High Performance Real Time Spectrum Analyzers shown on the Rigol Web Site.oh man, they should hire some real designers. This thing looks so strange with these deformated buttons and housing. This is a professional measurement device sitting in lab and not a new hot gadget from CES. Next year they will sell RGB illuminated fans as an option.
DSA815, DSA832, DSA875 Adding FRAM Write Protect
This mod. is to permanently retain the factory supplied DSA800 Series Trial Options (fully functional) forever. Suggestion - do it at least several hours before they expire.
Note: When they are gone, they will be gone forever, with currently no other way to get them.
I cannot get into the maintenance mode on my new DSA815-TG.
When I follow all of the key sequences listed on the web and in the Rigol service note, after hitting the STORAGE button I do not get the "Welcome to Maintenance Mode" message, and pressing the SYSTEM button does not offer a Service >You want to select the Maintenance Mode. Please just use the selection sequence for selecting the Maintenance mode using the 'DSA800 Maintenance Mode .pdf' (with a graphic display of the Keys). You have 9 button presses before you will see 'Welcome to Maintenance Mode'.
Marker table ?
Not exactly what you wanted however the info is in the Marker table and all you need is to do some simple maths.Marker table ?
Thank you for responding. No it doesn't seem that can do it, I tried. :-//
Just seems like it would be possible - conceptually it's not a complicated thing but doesn't seem to be implemented. Do the Siglent SAs enable that?

Yes that can be done of course by hand, I was looking for the instrument to do it but it looks like it just isn't something the designers implemented, not sure why.

Nice work IRB, I'm glad someone started to develop a 3rd party app for Rigol DSAs.
I have a few comments as well:Add the graticules to the captured trace would be nice. Also having more detailed analysis tools like spectrogram, projection of amplitude/power/frequency vs. time and waterfall graphs, in the app would make it a priceless tool as well.
BTW: Are you going to share the source code on GitHub or you want to keep it as a free licensed close source code?
For your information the DSA815 Upside-Down USB DSA800.JPG Screenshots were corrected in Firmware version 00.01.19.00.02. This isn't necessarily common knowledge because Rigol didn't mention this in their Firmware Release Notes for this version.
Thanks Peter, but :SYSTem:LKEY:TDELete just hangs up, and no button. I has dsa832 with .01.05.00 firmware. to bad ,thanks for help ,SteinHelp. I got 3 old out of date trials on dsa832. Do any one know how I can purge em? SteinIn the last firmware 00.01.19.00.02 for the DSA815, there is a new SCPI command with help text.

Peter
I can't get the SCPI command (:SYSTem:LKEY:TDELete) to work on my DSA875 either.
Just to be sure how should I append the License code in case I'm missing something, although I don't think so.
Ted
Edit: The command ':SYSTem:LKEY:TDELete' just hangs and times out. I don't think that the command is valid for the DSA832, or 875. All over standard commands respond very quickly.
Done. . . Ted

The signed capture mode on version 1.19 behaves strangely, it always on MaxHold mode , even in real-time mode. Does it work correctly on 1.18? If so, can I downgrade from 1.19 to 1.18?
Anyone has similar problem?
The Signed Capture Mode works correctly with version 01.18. I also think that version 01.19 works wrong. With version 01.19 the LAN connection works much better.
You can press the "Preset" button directly when turning on the device to install older firmware.
Peter
Does anyone have the firmware of DSA 815 version 1.18?
tv84:
Option AAAH works with my DSA815 SN: DSA8A1616.....

Thank you for this Information, never thought that this could work with my old device.
Karsten
Hi could someone please send (PM) me Firmware 00.01.16.00.03
Thanks in advance ;D
Hello, I have an DSA815TG:, mainboard: 00.04, radioFPGA: 00.05, digitalboardFPGA: 00.04, firmware: 00.01.09, . . . . I will hightly apreciate any help, Thank you very much in advance, Toño,Hello Tono:
Hello Ted,Damn, I'm very sorry, I didn't notice that you had Boot Loader .04. (Generally with the Hardware you have, Boot Loader .02 or .03 is incorporated). Sorry you won't be able to go back to FW .07, and your only choice is to solder Pins 7 and 8 of IC U1105 together (this should work fine). Although you could install a secure/hidden toggle switch, but be WARNED! - Never change the switch's from OFF-ON or ON-OFF when the DSA800 is ON (turn the DSA800 'OFF' first). The Data in U1105 can potentially get corrupted and you loose all the calibration data.
First of all let me say Thank you very much for your help.
Unfortunately I haven't succeed, that is what i have done: -> My BOOT is 00.00.04
So maybe this way is not valid for me or I am doing something wrong... I hope you could guide me. Toño,
Hello again Ted, It seems that last firmware is not compatible with my MOBO 00.04 and FPGABO 00.05, ToñoI'm quite sure that it is compatible. I have installed it on all of the previous hardware and software versions of the DSA815-TGs. You can send me a six pack of beer, Thank You Card, flowers, or etc. when you see all this working for you. Just kidding of course, but please go for it. I won't be leaving town anytime soon. Ted
Hello ted572, I have tried, but the DSA815-TG use always the IVI driver. And this driver worked not with the programs from Peter Dreisiebner. Best regards egonottoYou definitely need the Zadig USB Driver installed for using any of Peter's programs. Ted
Hello ted572, yes I have Ultra Sigma. And I have NI. I lose overview because I have Software from Rigol, Keysight, R&S and Cleverscope. For the DSA815-TG I use LAN. So this is ok for me. Best regards, egonottoYes, LAN should work fine. Have you reviewed the PM that I sent you? Re. The expected License Keys, and use of them (e.g. format, etc.).
Gentlemen,
Try dumping your own 4MB flash memory using the SCPI method:
https://www.eevblog.com/forum/testgear/spectrum-analyzer-rigol-dsa815/msg518691/#msg518691 (https://www.eevblog.com/forum/testgear/spectrum-analyzer-rigol-dsa815/msg518691/#msg518691)
With the dump, we can try something different... ;)
Ultra Sigma only works correctly with the dot as decimal separator. This must be set in the operating system under Region/Country.
But in Firmware 1.19 the format of the trace data was changed from Little to Big Edian. I suspect Ultra Spectrum works correctly with the current firmware.
On my website I have a demo program for the DSA, maybe you can do something with it.
It seems that I have to uninstall Ultra Sigma and National Instruments (500GB) to use you programs with Zadig. Am I missing sometime basic here, or do you have any tips on doing this?
Peter, the version you shared of Ultra Spectrum works great with my DSA on FW .18, thank you! I had to adapt the trial reset (https://www.mediafire.com/file/l4azhfcj8f4m3he/UltraSpectrum.v00.01.00.20-EEVBLOG.zip/file) for x64 systems and I'm now able to evaluate it further.Did you modify Peter's Registry entry for the Trial as it sounds like, or rather the Ultra Spectrum installation file (in your provided link)? Thank you, Ted

Yes - 00.01.19.00.03 is the latest version, and no Rigol for some unknown reason other than incompetence doesn't have it available on their web site. As 'Technix sys' pointed out in https://www.eevblog.com/forum/testgear/spectrum-analyzer-rigol-dsa815/msg2579409/#msg2579409 Re. DSA815 SSC-DSA/Signal Capture (SigCapture) Mode - DSA815 Firmware Update 00.01.19.00.03, 2019-03-25, corrected the SSC-DSA spelling of SigCapture (had been SigCpature).
Good evening everyone is new to the forum I have already had the pleasure of meeting marcopolo who kindly provided me with the filmware of the rigol dsa815 tg. Having never performed the update I would like to know from you if updating the filmware I enable the functions now disabled (swr emy etc.) and possibly what I need to do to enable them and then perform the change by joining pins 7 and 8. I currently have main board 00.04 freq board 00.04 filmware 00.01.05 of boat 00.01.02. kindly can you help me understand step by step what should I do Thanks Silvio
I've got the first 4MB dumped and there is a string like SECRET12345678AAAABB in my hex editor. Providing this key and the serial number to "rigup riglol DSA8XYZ... AAAE 12345678AAAABB" (0.4.2) doesn't seem to result in a valid code. All lowercase, no dashes.
I've been out of action for much of last year but now trying to catch up again, and having some fun with that....
My 815TG has Main Board Version - 00.08, RF Board FPGA Version - 00.05, Firmware Version - 00.01.13, Boot Loader Version - 00.01.04, and the soldered link to keep the trials running.
So far so good, but the firmware is well out of date and I'd like to upgrade that to 1.19.03, which I've got, in order to activate the 10Hz RBW, but reading through the archives I'm not to sure what this will do to the trials. Some posts seem to suggest it will remove them, others that it has but then they returned, or perhaps I'm not reading it right, so would appreciate an update on what to expect if I just go for it.
People said that I should connect pin 7 with 8, but I dont like it, because that means that all the store functions are not working after the mod, this is a big disadvantage of this mod.
System Setups will not work, only user setup-files, that is a big disadvantage. I am also not sure if the self-calibration works. I have to live with this disadvantage because I am not willing to spend 500 Euro for the math option. This is more than 50% of the price that I paid for the whole instrument. Without this option the instrument is very crippled in my opinion.
I used the write protection on the FRAM myself for some time. I did not notice any errors. The self-calibration works, the calibration data are in the flash memory.There are no errors, but you only can setup the instrument temporarily. All new system setups are gone after a reboot, you have the last state before the modification forever. Unfortunately the system setups (like network, usb etc.) are not stored in the user setup files.
I only had problems with the SSC option, firmware 01.19 and write protection.
Hope you remind, that a fan replacement has needs to fit more that just the mechanical dimensions. The noise of the fan is often reasoned by the air pressure and volume of them. I would not replace them, if not required.
The fan noise doesn't bother me because I don't use the device very often. I would only change the fan in the event of a defect.Hope you remind, that a fan replacement has needs to fit more that just the mechanical dimensions. The noise of the fan is often reasoned by the air pressure and volume of them. I would not replace them, if not required.
Normally they are overdimensioned by design. If you are in a cool enviroment (25°C) you can turn safely the noise down.
... tried 1.17...

If so, pm me and I may be able to help you. ;)
Hello,

Hi All,
my DSA815-TG shows this info:
Version of Main Board: 00.09
Version of Radio Frequency Board FPGA: 00.05
Version of Digital Board FPGA: 00.05
Version of Firmware: 00.01.19
Version of Boot: 00.01.04

1 TG-DSA800 Official Y
2 AMK-DSA800 Trial Y
3 EMI-DSA800 Trial Y
4 VSWR-DSA800 Trial Y
5 SSC-DSA None N
I have crawled through the thread. This is what I have understood:
- Boot 00.01.04 does not allow to downgrade to use riglol to permanently enable AMK, EMI, and VSWR.
- Connecting pin7/8 at u1105 prevents the remaining count-down trial time to be written to FRAM. With a permanent connection between pin7/8, some system settings will also not be written (LAN settings, USB settings, calibration data?).
=> What exactly are the settings, not stored?
- When using a switch between pin7/8 of u1105 the DSA must be switched off, then the switch may be altered, then the DSA can be switched on again. NEVER alter the switch while running the DSA or some data might get corrupted. And: Every time the DSA is started with pin7/8 open to allow changes to be written, a little amount of trial time will get lost again.
- Some guys reported that some other features/functions might not work or some erroneous behaviour might occur when using the dsa while pin7/8 are connected.
=> Right or wrong?
- There shall be an alternative solution using a PIC, that somehow prevents the trial time to be written. I have only read that there is a PIC solution, but nothing further.
=> Please can someone give a link or further information on that point?
=> Besides that, is there any option to enable SSC-DSA?
=> Are there other options I have not read?
Many thanks,

Hey @Kjo -
you may never have used an SCPI command and may want to read in that direction a little further. Hint: You can use Peter Dreisiebner's "Rigol Bildschirmkopie" software for this, Rigol's Ultra Sigma or a direct Telnet access if the DSA is connected to you PC via LAN. Search and read the forum for more clues on that if you don't know how to.
Then again click @tv84's link three messages above and follow the instructions of his very generous offer, it may make much more sense having done some reading before. And you won't need to worry about shorting the WP pin of the FERAM... ;D
Cheers and good luck,
Tom

Just leave the instrument running for some time with the FRAM unlocked. The eval counter will eventually reset and your trial licenses will become active again. After that, you can write protect the FRAM once again.
Hello DSA800 Hackers: I received a couple PMs asking me why I repeat 'Do Not install the Kegen's code for the '10 Hz RBW' and 'Tracking Generator' Options'. It is because some guys want to make sure that they have everything that the Riglol Keygen is capable of providing in the DSA800. Well these two Options are NOT Required, as the 'DSA800-TG' comes with a Tracking Generator (if you don't have a TG unit, you still won't, but it will falsely appear that you do) , and '10 Hz RBW' has been included in the firmware for the last several years. If you install them you will see repeat incidences of them when you view the DSA800s Installed Options, and that is a dead give away that someone played with the Rigol Option Installations, etc. I like to the keep the DSA800 clean and simple without adding miscellaneous un-required (potential corruption) data in the units OS. Although no operational problems have been observed from the dual installation of these two Options.
For the SSC-DSA license I was able to use the AAAH option in the key generator
// AAAR 0x00001 TG
// AAAB 0x00002 AMK
// AAAC 0x00003 RBW10Hz
// AAA3 0x00004 EMI
// AAAF 0x00005 VSWR
// AAAG 0x00006 PA
// AAAH 0x00007 SSC-DSA
a bit confused
I'd like to know if I should install the PA option key and what it's purpose is.
I'd like to know if I should install the PA option key and what it's purpose is.
It should be this.
I have my DSA815 open, and also measure 36 V in the unplugged state.Thanks Peter I just wanted to ask you about this 15V… So, it seems that the voltage regulator is not working correctly indeed at Vin I have 17V and 0 on all other pins.
Edit: At the test point TP1209 I measure 15.00 V.

The LM317 series of voltage regulators is short circuit / overload protected. So I wouldn't expect it to be broken in your DSA. Please check resistance from TP1209 to ground with a multimeter -- I'ld predict you will find a dead short. Now comes the difficult part: finding the damaged component that shorts this rail. The easiest approach is feeding a low voltage (sub 1V) at considerable current (>0.5A) into that rail by an external laboratory power supply and observing the PCB with a thermal camera -- you will find the culprit to get warm. If you haven't got a TC, you may spray some IPA (isopropanol) on the PCB and observe where it evaporates first.
If you don't find a short on the 15V rail, U1211 may have failed after all, just replace it.
I'm pretty positive that this DSA can be fixed without too much hassle.
Edit: Btw, what's that ugly stuff on the PCB near TP1201?
I wonder if you can identify the manfacturer of the capacitor in question ? It would be interesting to know.
Hi all , can someone please send me in the correct direction ?. Just bought a 815 tg , and the past couple of days reading this forum, but my old brain is not taking it in.
815 DETALS
MAINBOARD 00.09
RF BOARD 00.05
DIGI BOARD 00.05
FIRMWARE 00.01.19
BOOT 00.01.04
Can someone tell me if this one can be done and if so by software or short ?.
Any info would be greatly appreciated . thanks in advance..
Noob question, is there a way to mirror the DSA screen onto a pc WITHOUT taking control of it ???
If you control the DSA815 via SCPI, the local operation is automatically locked. You can unlock the operation via SCPI command. But if you want to read and display e.g. a trace all the time, this does not work with simultaneous local operation.
Peter
I tried sending the "ESC" key that did not work for me:
With every firmware version the SCPI command should work:
:KEYB:KEYV ESC
From version 01.12 there is a separate one for local operation:
:SYST:COMM:BRMT 0
Peter
Sorry, the commands are for DSA815, I didn't add that.
Peter
Here is an updated zip of the exe. Updated with two buttons one with the :KEYB:KEYV ESC and the :SYST:COMM:BRMT 0.
I hope they work, as I do not have the DSA815 near me.
Someone please let me know if one or both work.

While I wasn't able to grab a screenshot for some reason from my DSA815-TG over TCPIP (maybe a problem with my VISA install?), those two buttons both worked to release the remote connection (remote mode entered separately via Tekbox EMCview software).
The program was not written for TCP. I wrote it for USB control. I have not tried to connect my unit via the network port.
Does the top box fill in if you click the Find and Connect button?

OK. No the Find and Connect button didn't work. I typed in TCPIP0::192.168.xxx.yyy::INSTR and then clicked the buttons.
As I use EMCview for a lot of my measurements, I don't often need a screen grabber but it might be useful occasionally.
hi @ll
Noob question, is there a way to mirror the DSA screen onto a pc WITHOUT taking control of it ???
I have Ultra Spectrum and Ultra Sigma installed, tried some other pieces of softwares no luck, some of them relies on Libusb drivers, and don't detect the DSA ??
Kean if the code won't load for you I can pull the Win-sock, and re-post for you. Thank you for the feedback, and making me learn new things.
I hope you have time to try this again. You are the only one giving feed back and I appreciate it.
I added at text box with some debuging. It should show where in the program it's not getting to.
Thank you again.
Did you also get a message " No VISA resource was opened!" or
For future reference: The TG License Key should NOT be entered, as it is already active in all of the DSA800-TGs. So far it hasn't caused any known issues other than often showing up twice in unit's License Info list, and probably as expired, or similar for the one just added. And if you don't have a DSA800-TG it won't do anything for you, except that is to blog up your units firmware.
and the undocumented commands:
:SYSTem:LKEY:DELete
:SYSTem:LKEY:TDELete (new since 00.01.19.00.02 - "Delete all Trial version option license key")
I have never tried the DEL command.
I have been reading through this thread but I could not find an answer to this question:
-Is the DSA815(-TG) field-upgradable to DSA832?
-Is this purely software or (also) hardware? If so, is there -hypthetically- a hack?
IRB, Wolfgang: thanks for the insights. I supposed it would be this way but it was worth acking.
I wil investigate how to optimise the state of the firmware and options.
