Rigol DP832 - Firmware list and bugs

<< < (67/153) > >>

Omikron:
It looks like the DM3068 does not like the *TST command.  I've tried running manually via Ultra Sigma and it also errors out.  Reviewing the DM3000 programming guide does not show that there are any official test commands that are supported for any command-set.  Is this true?

To answer my own question, I downloaded the newest version of the programming guide which for reasons beyond my understanding is not published as a PDF but as a fscking Windows Help File (.chm).

I guess *TST? is a common IEEE 488.2 command.  Still no clue why it's failing.

Omikron:
Just called up to Rigol support and he said he's going to check with a co-worker and get back to me regarding the issue.

Omikron:
Update: They tried the same command with a DM3068 running the same firmware version and it provided the expected +0 response.  We are now trying to figure out if this is a bad unit or if it's a firmware bug.

What is particularly troubling is the fact that the self-test passes when started from the Utility menu, but fails via *TST?.

Edit: I realize that this is now more related to the DM3068 than the DP832, so if a mod wishes to move the posts into the appropriate thread, it would be appreciated.

Omikron:
Apologies for all of the posts, but this is becoming quite a frustrating situation.

I've now been able to get the test to pass and fail intermittently when issuing commands via SCPI.  Sometimes it passes, sometimes it fails.  I can only get failures via SCPI.

That said, the script *also* seems to have an issue in that it doesn't wait long enough for the response from the DM3068.  This is why the response to "*TST?" in the log just shows as ' '.
