Calibration problems at rev 0.0.4 #7

Open derfunker opened 4 years ago

derfunker commented 4 years ago

Something is wrong with the CAL routines... When doing S11 and S21 Calibration the errror terms are displayed on screen as described. But when the correction is activated only the S11 trace is corrected! Only when I have one trace (S21) on screen the correction works. In some cases the S11 sweep only works when the marker is set e.g. to center. I think here are some minor software bugs to find. In principle the device works fine! Thank you!

I found it. The bug was sitting in front of the device :-) Now I was successful with the Cal.

Thanks! One question: what is the maximum rf input level at port 2 (in case of measure of an active DUT) I would apriciate to know about any new software updates. Best regards, Klaus
