Spectrum Analyzer - Rigol DSA815

[Kjo]

Just acquired a DSA815TG supposedly new on ebay. Looks to work ok.Here are the pertinent numbers:
factory cal date: 2018/9/23
Main board 00.09
RF FPGA 00.05
Digital FPGA 00.05
Boot 00.01.04
Firmware 00.01.19

After reviewing this thread I see I have the first version of FW release 19. That means I cannot downgrade.
I have the AMK, EMI & VSWR trials active with ~ 35H-18M left.

First big question is how do I determine if this unit is still in the 3Y warranty period?
I have the factory papers with a blank warranty card. (No date of purchase or dealer stamp)
I have a conundrum in that I want to preserve the option timers, but may also be eligible for warranty coverage.

Appreciate any advice before I start using the SA.

Hi tv84,
Im a newbe to these DSAs and protocols for preserving option time on the various versions.
Im not sure what to with the pointer back into this thread. If you mean I should just apply the pin 7-8
shout that is ok. But I was hoping someone could confirm a method of determinind warranty coverage as well.

[Kjo]

I just called Regol NA Tech Support and gave them the serial #.
The unit was purchased in 2018 and is out of warranty. So on to the
switch patch of pin 7 & 8.

I wonder if someone has a list of the settings/features that do not get stored
when the pins are shorted?

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... 

Cheers and good luck,
Tom

Can you obtain this information?

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

You've got a PM, tx.

Thanks, SCPI works just like old 488 bus commands!
Sent tv84 PM and waiting now...

Hi
I purchased a DSA815-TG. After turning on the unit, the "AUTO" and "TG" buttons blink and the image is dark. I read here on the forum that it is a software problem - I tried the method by uploading the file FW 01.06, 01.07 and 01.19 to the pendrive and running with the PRESET button pressed. I formatted the pendrive to FAT32 and FAT - it did not help. I used a 512MB and 1GB flash drive. The diodes on the pendrive are off.
I don't know what the BOOT version is, inside the device on the motherboard is DSA815_V02.04 04-06-2014.

What am I doing wrong? I also read about the .04 boot version - booting the U1105 chip with pins 7 and 8 shorted. But that didn't help either.
Greetings

Hi,
I have boot version 1.03 and fw 1.17, all options (without ssc) on trail 0h and parallel all official on forever.
Years ago I used the key generator to get all options. Meanwhile I lost anything about from my head.

Questions:
- Is it save to update to fw 1.18 or is there a risk to loss the official option status?
- Is the boot version permanent or does I have to take care not to lose boot version 1.03?
- Could someone send me fw 1.18 - please?

Thx

Upgraded my DSA-815-tg to the latest Firmware 00.01.19 and lost all my Trial-Time.
now all Trials are gone...

Any way to bring them back ?

[Kartika]

Why you upgrade firmware  before you made hack on time chip?

[TurboTom]

After some time running, the eval licenses will miraculously become active again. This is, as far as I could find out, the result of the power-on time format in the FRAM chip having been changed between the versions. It may take some ten hours of operating time to reset itself, so be sure to check often as not to lose too much of the precious eval time. After it's active again, the WP pin mod may be a decent move, though this also inhibits storage of the instrument's last setup, network configuration and a few more "convenience" functions.

Reading back in this thread a few pages may give you hints to another approach to solve your problem, but that's nothing anyone can take for granted, while the aforementioned method works on any DSA... 

[Terefere]

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.

It's really true that counter will back?. Abyone else can confirm this?. How many time it must keep my DS815 in On state?.

Is any other way to turn on EMC in Boot 1.04 and FW 1.19. If I read good, then... no ;/


--------edit
I try to find info how to get read public key. If I understand good then I must made dupm of FRAM and I can do this by ethernet. Maybe somebody have link how to do it?

New owner of a new DAS815-TG. This appears to be a thread with a wealth of information. Looking forward to diving in and joining the convo.

Hi all,
please I need your help for an apparently bricked DSA815TG. (boot 1.0.4)

I performed the U1105 mod shorting with a solder blob pin7 and pin8 together.
Then I reconnected the power supply "on the fly (without closing all the chassy, and booted the instrument to see if all was good. And it was!

So I switched it off, disconnected the mains, and closed the chassy witj all the screws.
Then I switched the instrument on again and no display at all!!!
It seems that the backlight is turning on a little bit, but the instrument is irresponsive (the fan is ON).

I disassembled the instrument again and checked for cable anomalies but all is good; so I removed the solder blob and cleaned, but with no luck . The DSA seems to be near dead!

I am thinking to buy a new FRAM (even it will be empty then.....) to try if this helps...

Any help please ?

[swanawood]

hello, some updates:

changed FRAM, still no go.

I connected Olimex Jtag (with imx28.cpu config) , and this is the result:

adapter speed: 6000 kHz

dcc downloads are enabled

Warn : JTAG tap: imx28.cpu       UNEXPECTED: 0x227e40cb (mfg: 0x065 (Analog Devices), part: 0x27e4, ver: 0x2)
Error: JTAG tap: imx28.cpu  expected 1 of 1: 0x079264f3 (mfg: 0x279 (SigmaTel), part: 0x7926, ver: 0x0)

Error: IR capture error at bit 4, saw 0x21 not 0x...3
Warn : Bypassing JTAG setup events due to errors
Error: unknown EmbeddedICE version (comms ctrl: 0x00000000)


The fact it seems not to recognise the CPU, it means that the DSA stops at what stage ?

Would the trials return if the FRAM U166 is replaced?

[reha]

Hi,
I have a new DSA815 and still have trial time.. for the firmware 1.04, is there any "recent" information on extending the Trial period? is it secure to short circuit the IC shown at the video? many thanks in advance

[reha]

so, do we know if this "short circuit of pins 7&8" still works without bricking the device?

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.

If someone one wanted is there a SCPI command or way to remove  an installed key or remove all keys.

Used only a few times and after two years it was turned off, here's what happens.

Sometimes it ramains stuck at "Device initializing" with the RIGOL logo, other times the screen is completely black with no lights lit and you only listen the fan. Of course warranty is expired, the warranty seal is still intact and I don't know what to do. Do you have some experience with this kind of fault?
