While running FM waveform in my picozed sdr 1x1 with osc application, I'm seeing DC offset and IQ imbalance eventhough I enabled the quadrature tracking and DC offset calibration.
If I tried to correct it by using the profiles through shell script:
echo tx_quad 14 > calib_mode
for profile 11 I see minimum imbalance in one time but for the next time(with same setup) I'm witnessing different imbalance, which is not consistent.
I want to know how many profiles are there? Even If I put echo tx_quad 133 > calib_mode, its accepting.
How can I get consistent performance?
Is there any ways of creating my own profiles?
