No recalibration required. I've performed several firmware updates on two different Rigol DP832 units and they have never affected calibration. It's true we don't know exactly what was added/changed/addressed in the most recent firmware update. However, the issue you describe sounds like a firmware issue so I would update the firmware as a troubleshooting step. Just carefully follow the instructions HERE (pdf). Naturally, there are risks anytime you update firmware so you have to make that decision.

I asked this as well as the response I got from RIGOL was:
"We have high confidence in our updates, but there are always risks. We leave it to users to weigh what the update helps them do vs the potential risks. I see no reason it should need calibrated after the fact.

Altough I do not have the DP832 ,
I have found that the Rigol FW updates change the Calibration on the DS2000. And rightly so, as if there is a new feature added in the Software that makes a better/different calculation then there will be a change.
In my experience with changing FW back and forth. I have seen the Calibration change , but once I go back to the FW where the calibation was done , ALL still has the same Calibration.
I change FW to check for FW bugs. Is this a new bug or previously existing Bugs; (back 7 FW updates + x beta)
I assume Chris hopes a FW update happens easy and un-eventful :)

Seems there is new firmware for the DP800 available. Rigol's firmware update request form lists 00.01.14 firmware for the DP800. Anybody got this version already or any information what has been changed?
Macbeth:
I've just got the new firmware 01.14 by automatic email. It includes the existing bootloader 1.09.
Interestingly it also includes an 18 page document mostly in chinese detailing all the firmware releases and their changes to date :-+ :clap:
The changes from 01.13 are:
1. Change the USB Device library. (Mod)
2. Change the LXI and SCPI library. (Mod)
3. Add the Series-parallel help info in the main help. (Enchancement)
So, clear as mud then. I'm yet to install it...
