The order of tuning should be the same as the order of the sliders e.g. the Tx I DC Offset is
tuned first and Phase difference is tuned last.
Use <= , =>, PgUp or PgDn keys
The tuning is performed by setting each of the sliders to desired value.
Tune LO leak to minimum with TXI/TXQ DC offset control (f0 on spectrum analyzer screen).
Tune the wrong sideband to minimum using Amplitude/Phase difference controls (f0+68kHz
on spectrum analyzer screen).
