@tv84 do you have any comments on RSA3015E-TG tweaking up to RSA5xyz-TG?  :-/O

I haven't seen one so I don't have any comments. Or the PCB is the same as in some 3030 or i couldn't have seen one because they haven't been out yet...

Certainly that, at least, a BW upgrade can be done. Don't know about a model change.

tv84,

If the bandwidth upgrade and unlocking features can be done, The added realtime aspect would make it a very compelling offering against the Siglent new SSA3000X Plus models.  Because the Rigol spec is better, or equally as good, in most areas, with a $200 price difference.

Is the 1Hz RBW possible on all the RSA3000 models, unlike what is listed on Rigol's website: https://www.rigolna.com/products/spectrum-analyzers/rsa3000/

I suspect the 10Hz mentioned there is the default, with an option able to enable 1Hz resolution, but I don't see a "RBW option" in any of tv84's photos posted.   :-\  Could someone clarify?

Hello, on RSA3000E is standard, on RSA3000 it needs the option RSA3000-BW1

Thanks for pointing that out, Simone!  Can you tell us further about the `E` models?  Did anyone take it apart yet?   :-/O

About RSA3000E, we feel the price is more centered, in fact since the E models are out more and more customers are approaching us for such model. So far the main application is EMI pre compliance. If you like to see anything special just let me know.

So to clarify things, the model 3000E runs a slightly different app than its older brothers 3000/5000.

As such, any "model change" will only be possible between models 3015E and 3030E (same for TG versions).

For 1500€ (+VAT) fully unlocked RT SA and up to 3 GHz still a good deal

That seems perfectly possible.

I'm thinking about getting a 5065-TG. Is anyone else seeing these spurs?

Hi, we had a demo unit for test.
I was surprised to find that internal spurious emission is much worse than on DSA875-TG. e.q. peaks every 10MHz from 0-100MHz, every 100MHz above 1GHz etc.

Or any other problems? Thanks.

Never had any of the issues at all regarding those quoted, we have a R&S 13Ghz SA and its looks pretty clean on the Rigol RSA 3030 as it does on the R&S driven by a HP/ Aglient 4433b SG.

I use the RSA every day I find it easy to fly, and intuitive and accurate, our unit has the OXCO fitted as well, though what i do find extremely useful is the multi domain analysis when coupled with the MSO7000 (hopefully before Xmas a 8000)

To have this kind of facility would cost a lot of $£$£$ that  from other companies it works just fine and it produces reliable accurate results I depend  Debug heaven.

The RSA upgraded really does deliver high quality performance and features plus the hdmi output is a nice bonus as well plus the CISPER emi features are very useful to.

It fashionable to knock Rigol and Siglent, they are but small players however they are some great products these companies produce which not only VFM but performance as well.

We have other test equipment from the big three as well, and a Tek 6 series scope on order for the research lab, but the daily Rigol fliers we have really do cut the mustard. Would also suggest a look at Picoscope some quality products in there at almost realistic prices

I'm sure Martin72 will poo poo the thoughts and say 12 bits are much better than 8, while I agree, it purely depends on what you are using these products for.

We are a SME so small staff company but multi talented personal across a broad spectrum of electronic disciplines not just one or two people just pass testing or finial power analysis. 

Non of the equipment is net connected, they are used in conjunction with lab servers, no pass/fail continuous testing etc

The equipment is used daily and is used a great percentage of their capabilities not just one or two aspects.

Yes, this is one of the things I'm interested in it for, although I'll be planning to use it with a Keysight scope. I presume the IF out is just an analog signal that can be hooked up to any BNC scope probe connector?

Hello srce

Yes that is way I hook up along with a dedicated trigger out/in from each device 50 ohm bnc.

For extra accuracy you can use a Rb or GPSO ref clock.

It does make quite a decent debug package for RF and IoT, I am lucky enough to have the 'mystical' RSA fully opened up, full bandwidth and all options.

Have used the RSA with a new 5 and 6 series Tek scopes even the ref was somewhat surprised lol

Hi Sighound36! thank you very much for sharing your knowledge and experience of the Rigol RSA -- I think you are the only one giving first-hand user experience!!!  :-+

It is awesome to hear possibility of using GPSDO for 10MHz clock input for higher accuracy...especially I recently bought Symmetricon GPSDO and plan for 10MHz distribution to my test equipment.  :D

I am curious to know more about your comments:

I wonder if there is significant improvement to get RSA with OCXO option if one plans to use a GPSDO 10MHz reference for their equipment.  Clearly OSXO is excellent to have without GPSDO, but with the latter time source i suspect it will override the OSXO clock?

Do you think OCXO option is worth paying for?

Thanks for your comments! :)

Hello Sparky

I am sure they are one or two other RSA users on here as well, so their contribution would also come in handy to  8)

We are lucky to have a couple of reference clocks in the lab, one Rb one GPSO.

The OXCO upgrade on the Rigol RSA does make an appreciable difference especially as well the unit 'off site' at customers as well.

Taking a master clock along is not a viable proposition! Yes you do notice a positive difference with the clock upgrade, you may not have to take your RSA out on 'missions' so you may find for the cost outlay just constructing a decent ultra low noise power supply for the GPSO will work absolutely great for you.

The way I have viewed this is simple most of the labs (professional) we deal or have dealt with, all use some form of master/slave reference clocking system, and pretty much all their scopes/SA/VNA's have the OXCO upgrade as well.

I feel personally it makes a difference others may not, however one issue when considering this method quality cabling or the correct length.

Nice to see a fellow RSA owner stepping out of limelight!

I do feel that having the upgrade internal clock  is worthwhile, however for the outlay you can built a really top notch GPSO and have enough left for a good time away on a Rugby weekend outing!

I will also state definitively that tv84 is the man.

As for the RSA3015E, I'll sing its praises all day long. My daily driver at work is an old Agilent E44xx series, and I vastly prefer the RSA. It performs better (going to be even better for low-level signals now with the PA), the UI is more responsive, and the way the menu options operate is more intuitive.

I didn't get the OCXO option because I haven't needed it. For most of my use cases the internal oscillator is good enough (I've watched digital clock drift on the real-time spectrum analyzer). In almost everything I build I create a 10MHz output, and the RSA locks to that without issue. I can see how you might want a ppb clock if you don't have that option.

The only negative I can think of for the RSA is that I haven't had great luck with the remote control software (UltraSpectrum). I basically just wanted to use it to make screenshots easier to grab, but the application doesn't display properly. Of course, the USB works just fine and captures images to bmp, jpg, or png... unlike the old Agilent E44xx I use at work that has a floppy disk...

I would say for $2k, if you need a spectrum analyzer, don't hesitate.

Thanks for visual confirmation!  Amazing tv84! :D

This is gonna be really great news for tons of ppl out there!   This seems incredible possibility of RSA instrument at very relatively cheap price.   :-+

I compared some specs difference between RSA3000E and RSA3000 -- it seems the majority of difference, after options are added, is the real-time analysis bandwidth and parameters related to that.  It's also $2k vs $5.8k which is a huge step. 

I'm thinking this `E` model could suit my needs best.  I'm only doing BLE stuff, so not needing above 3GHz.  I think the lower phase noise, DANL, and higher bandwidths that are possible with non-E version is "nice to have", but beyond my needs...hard to justify the +$4k for that.

Thank you very much for the continued updates!!!  :-+  :-/O

I decided to read up on the OCXO option, which seems user-upgrade option.  A few findings from the user guide to share if anyone is interested:

- During the start-up process, the spectrum analyzer recognizes the OCXO module automatically and synchronizes with the OCXO module. Note that at this point, no external sync signal is allowed to be connected to the spectrum analyzer.

If you're working in an environment where you have GPSDO and distribution for all equipment, then you're more likely to be using that so OCXO is no use.

- After the OCXO module is installed on the spectrum analyzer, the OCXO module will still be working if you only turn off the Power key on the front panel without cutting off the AC power supply on the rear panel. Therefore, please cut off the AC power if you do not use the spectrum analyzer for a long period of time.

I can understand that warm-up time of OCXO and stability is best if left on, so this makes sense.  Probably want to be using the RSA daily though.

Since I'm not taking the RSA elsewhere and therefore don't need portability of build-in high accuracy clock, I would not get the OCXO option.  And...it's available as separate module if needed at a later time.

I have no hesitation in recommending the RSA for this task, the EMI package is very good, takes a bit of getting used to, however we use this function regularly, and especially with the 40Mhz RT bandwidth examination of any spurious artifacts are easily observed. Lots of options with the EMI app that will make life easier for this task.

Does anyone know if these contain ARM CPUs or x86? Datasheet doesn't mention it, just that it runs Linux. Can you ssh in? I'm just wondering if it's possible to develop and run your own apps on it.

Has anyone tried external HDMI monitor?

The main display has resolution 1024x600 (Datasheet), and the HDMI resolution is configurable up to 1280x720 @ 60Hz (Users guide).
 - I wonder if using HDMI impacts any system performance?
 - Does the increased resolution and use of external monitor (say 1080p capable 22") help with usage?
