you mean average for FFT?

Yes.

Hello,
now I have tried the 100 MHz license. BW is about 120 MHz.
Rigol 20 MHz with 50 Ohm termination:
1 mV/div: noise is about 21 uVrms
1 V/div: noise is about 4 mVrms
Rigol 120 MHz 50 Ohm termination:
1 mV/div: noise is about 58 uVrms
1 V/div: noise is about 8.5 mVrms
Best regards

egonotto:
Hello,
However, the calculations of DHO1000 are not trustworthy. You can also get a noise of 4 mVrms at 1 V/div instead of 8.5 mVrms as in the first measurement.
Best regards

Could the test setup (moving probes or lights/appliances) influence the measurement?
I live close to military training grounds, and sometimes I get AM interference.
egonotto:
Hello,
I don't think so, because you can often bring about this change in the measurement results by different operations (switch on the second channel, add measurement, switch off the second channel, delete the measurement), can bring about this change in the measurement results.
