The Spectrum Analyzer now shows a plot like this:
The purpose of this tuning is to tune the carrier signal and the +67kHz signal to a mini-
mum level (Marker 2 and 3).
Use the variables 'TX I DC offset' and 'TX Q DC offset' to adjust the carrier signal to a
minimum level (Marker 2).
After tuning to the minimum the level difference between the peak levels at marker 1
and 2 must exceed 40dB.
Tuning is possible by using arrow keys on the keyboard. Pushing the sliders by using the
mouse is less sensitive but even possible.
