New Rigol 16-bit function generators DG800/900 series

[rf-loop]

Small question

Is there a way to change the way numbers (and especially thousands) appear on the DG8XX DG 9xx series ?

It's extremely errorprone (for me) to see "90 Hz" written as 90.000,000 Hz

Delimiter: point, comma, space, none
Decimal: point, comma

But there is one bug from long long buglist. If select decimal ,  it still display .
With decimal set , and delimiter none: 90.000000 Hz
With decimal set , and delimiter space: 90.000 000 Hz

So I can not set it for 90,000000 Hz what is perfectly right in my homeland.

[CeD]

Yes, I tried and

DOT : displays 90Hz as 90.0000000 Hz : it's better than nothing ;( I don't get why they insist on displaying useless zeroes
COMMA : displays 90 as 90,0000000 but, but if you hit the keyboard, (like to enter a new frequency by hand) it reverts back to 90.000000 in the keyboard screen so yeah...

So I used "dot" with separator "none" ; as at least : it's the same everywhere.

I'm not complaining too much as this is entry level hardware, but it's a bit sad that such easy to fix bugs remain so long.

Excuse me for parachuting into this topic.
Are you telling me if I buy Rigol DG811 I can hack it into 100MHz/2 channel generator?
I'm looking for my first signal generator. Would this be a better option than UTG962 and FY6900?
I'm into amateur radio beside electronics so I thought it might be a good option to look for something that can do at least 50MHz.

Yes and Yes.

Are these still crackable i.e. if I grab one with the latest firmware, can I roll it back and crack it?

[tv84]

I would say yes.

Ok I got a DG811 and it has unlisted firmware 00.02.05.00.00 on it. hold my beer 

Procedure so far:

1. Downgrading to 02.04.00 at the moment. Did this as the 02.05 firmware is unlisted and unknown ... tested OK
2. Installed GEL file from https://drive.google.com/file/d/16nC-uJ12MXilJElv4Eukvt1IW4RzGdb7/view?usp=sharing (reboot it and whack help) ... tested OK
3. now thinks it's a DG992 but with 01.08. ... party.
4. Install https://www.eevblog.com/forum/testgear/new-rigol-16-bit-function-generators-dg800900-series/msg3119264/#msg3119264 GEL file (finish upgrade 02.04) ... OK
5. doing 02.04 upgrade next... OK went straight in fine.

Ok so I have a DG992 with 02.04. Thanks again tv84 and everyone else who was involved in this 





I would update the serial number but Ultra Sigma is still downloading and I've probably shot the warranty now anyway

v2.05 here.

I think you should have corrected the S/N earlier but I'm not sure.

[bd139]

Ahha. Not really bothered TBH - works which is the important bit.

[SMB784]

Is there a change log for the 2.05 firmware? Does it provide anything useful?

[bd139]

Wasn't that problem already solved in this thread? 

[tv84]

Wasn't that problem already solved in this thread? 

It seems this has became official support.

SO glad they fixed that major issue

Just to make it a bit nicer, if anyone has a Dymo label printer, this label is close enough. Just needs careful cutting out. Monochrome unfortunately, but better than staring at blatantly false information on the instrument's front.

Edit: Works on my LabelManager PnP printer, 12mm / 1/2 inch D1 cartridge, Dymo Label software on MacOS. Might not work on other types of labels and software/hardware.

This script replaces the previous one and also downloads the calibration files so that people can analyse them.

Hi tv84,

After backup the DG811 calibration files, if upgrade firmware broken the calibrate, how to restore the calibration files to the same DG811?

Thanks!

[Wintel]

Thanks for your kindness, but I am only care about Rigol DG811 & related issues now.

With 02.05  first you need do is take cal and memory copy, just for cases something goes really bad. If you do not afraid this can jump over.
There is available method for this backup copy...

https://www.eevblog.com/forum/testgear/new-rigol-16-bit-function-generators-dg800900-series/msg3272174/#msg3272174

Just including .GEL file to USB root and insert USB to running DG and when it ask you want FW update then yes (aftere then it run this small script). It write this data to this USB flash. So you need many USB or take them out and save.

Note, NAND backup takes long time and after it is ready rolling image stops rolling but it do not finish... I wait 5 minutes after rolling image stop  and after then I shot DG off and take USB and read... all was there. I think it can also just pull out without power off.
This backup calib is much faster and after some time it stops and goes out. But  if you do not take USB out then after some time it ask again do you want update... just cancel this.
after this or if you have jumped over this backup...

Hi rf-loop,

After to do the full NAND backup, how can I restore the whole NAND backup file to DG811?

Best Regards,

[Wintel]

Hello everyone!
My DG811 version is 00.02.04.00.00, and I upgraded to 992 according to the method provided by Vtech.
But the output voltage is very different. What is the reason?

Hi jscm2000,

What is the Cal State: in System Info Menu of your DG811 after upgraded to 992?

Calibrated or Uncalibrated?

[tv84]

After backup the DG811 calibration files, if upgrade firmware broken the calibrate, how to restore the calibration files to the same DG811?

How did you broke the calib files? If you didn't mess with the files explicitly I don't think you can break them...

To restore a NAND dump you need to go into bootloader mode (open the device, get yourself a UART connection, etc, etc).

Ok, I will try and do a backup first.

Are you willing to share how you managed to calibrate your unit that you upgraded to a dg992? We have been beating our heads against a wall with no luck for half a year now.

Have you try to upgrade to firmware 2.05 after upgraded to 992?

Got my DG812 last week and have been playing around with it. In general I'm happy with it. Being new to AWG units my only previous experience is based on FY6900 so I guess it's easy to impress me.

Rigol is providing their PerformanceVerificationGuide.pdf on their web I decided to run few tests with my DS1102Z-E scope. I'm puzzled with AC Amplitude Accuracy Test results (attached pic, my measurements are in red)

How it is possible that Peak-to-Peak results are not in correlation with Vrms results. Also anything beyond 500mVpp are out of spec. I cross checked my scope Vrms values against HP34401a DMM and they are in the same ball-bark. So scope is functioning properly. btw RG316 cable is properly terminated with 50 ohm at scope end.

Probably some small spikes or noise confusing the Vpp results. Try turning on averaging, high resolution mode, etc.
