Sounds like you would be a great candidate for trying v01.16 firmware (see link in first post -- in the list of firmware)!  Hopefully it will solve your reboot problem!  Let us know!

Is it possible to just reinstall v1.14 after upgrading to this semi-official v1.16 beta firmware?

We're using the PSUs in a production environment, therefore I can't install a not really officially released firmware on all units. If downgrades back to v1.14 are possible, I might give it a try on the unit I'm using on a daily basis, though. As I'm unable to reproduce the reboots in any known way and they seem to occur pretty randomly and sometimes not at all for weeks, it might take quite some time to get some results.

I'm not sure about downgrade from 1.16 to 1.14.  As you have some concerns for your production environment, perhaps you can ask Rigol about downgrade option and also to confirm with them that v1.16 is designed to address the reboot issue.  Other people here already confirmed that but you can always check.  Maybe Rigol will eventually release v1.16 if they realize the reboot issue is more widespread.  So, doesn't hurt to check things with them before giving it a shot.

Unfortunately I don't have any contacts at Rigol. Just regular bug-reports via their website and it seems several guys here on the forum tried this already without getting more information?!

I guess I just give the v1.16-beta a shot on my PSU. It is one of our oldest units (about 5 years, now) and if v1.16-beta has some really bad issues and can't be downgraded back to v1.14 I guess it just broke down... ;-)

Due to the random nature of the resets I guess I won't really be able to tell, whether v1.16 fixes the resets or not, unless I still get resets even with the newer firmware. If I don't see resets, it might also be just a lucky run, like I also seem to have with v1.14 some times (sometimes not a single reset in several weeks of daily use).

Ok, some information on the v1.16-beta upgrade:
  • Probably most important: my unit didn't catch fire (your mileage may vary, though)
  • Upgrade to v1.16-beta is done exactly like previous releases; for the mainboard as well as for the two analog boards
  • Downgrade back to v1.14 can be done without problems just the same way
  • Quite a lot of the configuration seems to get reset to factory(?) defaults,
    • e.g. "Display Mode" returns to the "normal" setting, OVP and OCP are disabled, Limits get reset to maximum, Language gets reset to Chinese
    • yes, it feels a little disturbing when you install a mysterious beta-release and immediately after the upgrade you are greeted by a warning dialog, which you can't read because it is in Chinese... - guess it was just the "USB device detected" dialog.
    • Files saved on the internal storage of the PSU didn't get erased during the update, though.
    • Voltage output and current measurements don't seem to have changed after the update either, so I suppose the calibration data seems to have been retained, as well.
    • For DP8xx (non-A) users: no, unfortunately I have no idea if your installed options will be reset or retained.
Version information before update
Code: [Select]
Digital Version : 00.01.14.00.03
Analog Version  : 01.02.04.01.02.04
Boot Version    : 01.09
Keyboard Version: 01.01

Version information after update
Code: [Select]
Digital Version : 00.01.16.00.00
Analog Version  : 01.02.05.01.02.05
Boot Version    : 01.09
Keyboard Version: 01.01

If I still notice any more sudden resets with v1.16-beta, I'll let you know immediately.

My DP811 still resets itself once in a while, even after I updated it to F/W 1.16 beta. AFAIK F/W 1.16 was meant to solve the problem of the frequent network dropoffs.

Since the analog hardware of the DP811 is considerable different from the DP832 (which I've also got but didn't notice a single reset event on that one...), I guess the problem is related only to the front panel board. It's quite interesting to see the problem really appears to be more wide-spread than anticipated. And apparently Rigol hasn't got a solution for it yet.

Thanks for summary!  Unfortunately, though, as TurboTom correctly reminds us the 01.16 firmware was for resolving Ethernet network dropout issues...not random reboots...  Apologies I didn't remember what the firmware addressed.  If you have issues, at least you can downgrade back to 01.14.

Thanks for the reminder, TurboTom.  I'd forgotten that 01.16 was for the Ethernet issue.

DP832/A Firmware 16 version 00.01.16.00.00 was a Beta release, although the current version 00.01.16.00.02 is a official released version.

Edit: Added applicable improvements.
     
    Support for USB-GPIB
    Fixed *OPT? command
    Fixed cursor settings
    Fixed LAN Library (network stability)
    Other. . . .

Funny: the official 16 release seems to have downgraded my analog boards, again:

Version information with v1.14.00.03 official release:
Code: [Select]
Digital Version : 00.01.14.00.03
Analog Version  : 01.02.04.01.02.04
Boot Version    : 01.09
Keyboard Version: 01.01

Version information with v1.16.00.00 beta:
Code: [Select]
Digital Version : 00.01.16.00.00
Analog Version  : 01.02.05.01.02.05
Boot Version    : 01.09
Keyboard Version: 01.01

Version information with v1.16.00.02 official release:
Code: [Select]
Digital Version : 00.01.16.00.02
Analog Version  : 01.02.04.01.02.04
Boot Version    : 01.09
Keyboard Version: 01.01

Does anybody know what was changed in the analog version 01.02.05 version contained in the 16 beta release?

Hello:  I'm not sure what it is your looking for, although this will probably give it to you and much more.

Did not want to necro the "bad design investigation" thread and ask here prior to opening a new thread in case I missed an old topic that already has the answers.

Channel 1 on my DP832 died. It just dropped to 0V and now stays that way. There was no magic smoke etc. and visual inspection does not give me any pointers so far.
1: Are there any schematics available that I missed?
2: Is this an issue that has been addressed and solved? (I found a mention of defective channel 1 in one of the postings, but there was a whole unit replacement without further investigation)

I had the unit working close to the max. voltage of 32V @50mA with a COB LED connected at the time when the channel simply died.

I would gladly take any pointers from you to save me some time poking around on the board!

No shematic that I know of, but it should be fairly easy to trace the signal back to the ouptput transisitors and check if these are ok. Does the unit give any errors itself? Does it show that the ouput is on?

No error message of any kind. I can still configure the channel parameters as usual, only thing missing is output voltage.

This gives you a little idea about the topology used, but it is not much.

For this kind of problem:
- check output transistors
- check power supply voltages
- check all opamps (opamp ok= zero voltage between inverting and non-inverting output). If not the case, start looking more in detai.

Thanks! Will be a couple of days until I can get to this ("long weekend" duties ahead :)), but will keep you posted on my findings.

There are also several fuses soldered on the power boards close to the terminals where the transformer is connected. Did your LED survive the incident (i.e. no momentary overvoltage/current was present at the PSU's output terminals)? In this case, I'ld assume it's not the pass transistor that failed. Maybe a logic/control circuitry supply problem on the related power board?

Short update of the story so far:

All the fuses on both boards check out fine, so do the current sense resistors and diodes on the outputs.
Output 1 can be switched, the relais works and the on/off LED signals an active channel. Display reads 0.000 for all values, which is correct. Everything seems fine apart from the missing voltage on CH1.
Will have to dig a little deeper...

Sandra: 

The link provided above for the firmware looked suspicious to me when I opened it up.
If you are interested, I can email the firmware to you.

Edit: The site recommended by JDub to try for getting your firmware " https://www93.zippyshare.com/v/97R7Ltey/file.html " is definitely in my opinion a site to stay far, far away from.

The v1.16 GEL must have CRC32 = AE86CF4E.

Hi, I've just received a new DP832 unit.

Version information :
Digital Version : 00.01.16.00.02
Analog Version  : 04.02.04.03.02.04
Boot Version    : 01.09
Keyboard Version: 01.01

All the options were activated just fine using riglol.

Thanks for the useful info on this blog !
