Hi,
So I have now played around a bit.
Nothing "strange" has happened in the meantime.
But at first I didn't measure anything, nothing was displayed except ***- "thanks" to the new analysis gate.
Then as specified 20M and 200M, looks normal compared to your measurements.
Interesting though:
This was measured in a cold state, after approx. 10min the now familiar message "Calibration completed" appears - And lo and behold....
Ch4 is now significantly better, has come much closer to CH1.
We should keep this in mind when "serious" measurements are due.
First of all, wait...
