Basically I'm asking, have others had a good experience with 01.16 or are there any issues with it.

Has less issues than 01.14.

The firmware upgrade instructions are quite dodgy at best.

I even found this which isn't much better.

https://www.bitsammler.de/downloads/Manuals/RIGOL/DP832/How%20to%20update%20DP800.pdf

#1 - Start the unit with the USB stick plugged in or not? or turn it on, press help, THEN plug it in?

#2 - After main update, what does "move USB flash" mean? Remove it? Does the help help m4 m2 m1 update without need of the USB stick?

#3 - What is the warning in the official Rigol instructions about bricking it if you install twice all about? I don't want that.

Is it so hard to have simple clear concise instructions!

alank2 · « **Reply #728 on:** June 25, 2020, 01:29:07 am »

I got it.

It was picky about the USB stick though.

#1 - find a USB stick it likes, plug them in until it recognizes one.
#2 - unplug it and copy GEL file to it.
#3 - turn dp832 off, turn it on, when seeing the rigol graphic press and hold HELP.
#4 - it will prompt to plug in stick, plug it in.
#5 - it will do the update. At the end it says to power cycle, but if you wait, it will reboot itself.
#6 - I had to set mine back to English language.
#6 - now you can press help help and do the power boards. first m4, m2, m1 and then m4, m2, m2.
#7 - reboot the whole thing.

If a DP832 has been told it's a DP832A using the magic USB stick, will applying an official GEL file update result in the PSU staying as a DP832A?

alank2 · « **Reply #730 on:** June 25, 2020, 12:10:49 pm »

I keep seeing this mentioned, do you mean that features are unlocked on the DP832, or do you mean something that makes it think it is a DP832A instead? I'm not familiar with that.

edit : Is it that with a specific usb stick "magic stick" you can use the set model command?

Sure.

Read the thread starting at page 10. You can make a 'magic' USB stick and then issue a SCPI command (while the 'magic' USB stick is plugged in) that tells a DP832 that it's a DP832A; after that, all the features of a DP832A are unlocked and the SysInfo reports that it's a DP832A. It's highly likely that this is how the Rigol factory decides what PSU is what version. You can't change to a model that is not the same hardware e.g you can't change from DP831 to DP832A.

What differences are there if you have a DP832 that is already unlocked?

Just the font and displays?

Are you guys running the 01.16 firmware now? I'm on 01.14 - should I upgrade it?

You should know that there are two firmware 01.16. Early received from support and late officially released. Judging by the forum earlier it was better. But I haven't tested it myself.

Managed to get my hands on a DP832 and calibrated two channels so far and getting -low mV on those. Tried 3 times and getting same results. Not touching/calibrating the remaining one (CH3) as I need this one to work in case the CH1 & CH2 are ruined. Using a DM3058E as ref/source and the SCPI procedures & table found earlier in this thread.

CH1 0V/OFF == -46.3mV after calibration
CH2 0V/OFF == -151.1mV after calibration

CH3 0V/OFF == 0mv (untouched factory calibration)

Used to be all 0mV before calibration. Are those two channels' ADCs fried and do I need to get myself another DP832? Easy repair maybe??

Any advice (help!) welcome

@Mecanix:

You may want to have a look here, the peculiar behaviour of the DP832 when calibrating the low end of the voltage range, is dealt with there to some degree. It should be possible to get the offset sorted with this information, yet, as it seems, only by means of an automated calibration.

Mecanix · « **Reply #740 on:** July 17, 2020, 03:03:47 am »

That's great, thanks. I'll sure have a look and see if I can at least understand what went really wrong at the first place; unlikely I'll have a go at further modification until I've understood first. The unit appears to be destined to go back to factory for repair/re-calibration, from the look of things (-151.1mV... yikes lol).

Quick question, if you know; when I get back into Utility > ManualCal > CallItems: only a handful of them registered (7?) although I was referred to a 35 points table. What went wrong? Tried Board's ADC calibration from the gui and that also fails. What exactly blew up? anyone knows?

EDIT: quick shout out to the folks who've contributed in the thread TurboTom shared (and who've contributed too), that fixed the wicked offset on the CH2. All what's needed now is to attack CH1 with a tighter custom points/set and all good to go, I think, dunno lol

Certainly better than -151.1mV where stuff would have seriously blown-up if left on the PSU, even when the channel are switched to OFF. Scary stuff. Do NOT attempt this 'diy cal' if you can't program/script logic yourself, and/or don't have one (or two) days to waste (I'm almost 7hrs in this and only half done lol). Recommend sending off your unit to the factory and be done with it.

I've just got around to try to "upgrade" firmware on my Rigol DP832 to newest version and it looks like my firmware is bugged out. I can't do it. It starts and then it just rolls between 19.2 and 19.1, whatever that means.
When I reset the power supply it powers up and works fine.
I have:
It was calibrated on 04/18/2013
Digital Version 00.01.03
None of the options are present. But everything works. I've connected it to LAN and it's communicating, responds to inquiries I should say, because when I've tried to send the command to switch it to A model it doesn't accept it.
That's actually how I came around to try to do the the firmware upgrade, thinking that it may solve the problem.

bson · « **Reply #742 on:** October 25, 2020, 07:45:12 pm »

Try a freshly formatted USB stick with only the update on it. Maybe a different one.

Otherwise it sounds like a hardware problem. Either the internal supply for the logic, or the flash itself.

Ordinaryman1971 · « **Reply #743 on:** October 25, 2020, 08:53:28 pm »

I've tried two different ones, and two different updates.... let me make a third attempt.

@Ordinaryman1971

"Digital Version 00.01.03" is a very old firmware and some time after v01.03 Rigol also updated the Bootloader-Firmware - I think even twice (once in v1.09 and once more in v1.10) - which must be done separately (same instructions, just a different file that must be installed first). Did you try this?

The current 01.16 firmware archive file, that I have here, doesn't seem to come with the updated bootloader anymore. Previous versions of the firmware archive file downloaded from Rigol always included the updated bootloader image, as well.

Maybe you have to get an older firmware archive file, first, and use this to update to a newer bootloader version for the v01.16 update to work?

JDubU · « **Reply #745 on:** October 26, 2020, 06:48:47 pm »

Here is firmware version 1.14 that includes the 1.09 bootloader.

Ordinaryman1971 · « **Reply #746 on:** November 04, 2020, 05:07:30 am »

Thank you very much. That was a problem. Old firmware and bootloader. It was tricky though. After updating to ver. 00.01.14 I've started getting overtemperature errors, couldn't enable either channel.
I've also got an error on analog board, failure to pass selftest.... But I've loaded ver. 00.01.16 and all went back to normal.
The "upgrade" went through without problems afterwards.
So, the 00.01.16 is the newest firmware published?
But I think I have another problem on hand... look at the bottom unit and the current leakage.
And the power switch so dirty.. I swear I've got it like this.

JDubU · « **Reply #747 on:** November 04, 2020, 05:28:54 am »

Latest firmware version is: 00.01.16.00.02

Could be a false readout due to calibration being off.

Hi,
I want to calibrate my DP832 through the manual process with a Brymen BM789. I know it's not perfect for this, but for me it's enough.

Is there anything I have to consider before doing this?
Do I have to send a clear calibration scpi command before trying?
Firmware version 1.16 is installed.
