As far as I know, you don't. Nice people on this forum tell you how to get it back ;)

@ marmad
I just wonder if the "better" brands i.e. Tek and HP exhibit thermal drift at max sensitivity settings? Maybe Dave can attest to this since he has reviewed them.

@jsykes: I'm just not sure thermal drift is the correct description of what's happening. I always thought of thermal drift as an unintended or unplanned drift away from the normal operating parameters due to temperature. When I turn on my DSO and watch the traces, it appears as if Rigol engineers have calculated the normal operating parameters to match exactly with the stabilized operating temperature of the internal circuitry.
Again, it's no coincidence that DSO makers always want you to warm up the scope 30 minutes before doing a self-calibration (and some of them mention doing it before making delicate measurements). The specifications of the DSO are accurate only for a stabilized ambient temperature.
Galaxyrise:
It's not just DSOs, either. Quoted from the Agilent 34401a calibration procedure:
* Assure that the calibration ambient temperature is stable and
between 18°C and 28°C.
* Assure ambient relative humidity is less than 80%.
* Allow a 2-hour warm-up period before verification or adjustment.

Hi guys!
A quick question, I hope I didn't miss it being already covered in the last 78 (!!! :-+) pages. Having used my scope several times now, I still can't get how to enable or disable measurements from the left-side meu. I find it very hard to see the logic of that. Sometimes new measurements appear on the right side, sometimes it shifts the older measurements and appears somewhere between the already activated ones. Is there any way that Rigol will change that very annoiing behaviour any time soon?Thank god they listened to us about the inverted X-Y mode...
