TX Calibration - When?


#1

Now that the transmit side of my software is working well, it’s time to get the tx calibration perfected.

If the drive level set with LMS_SetNormalizedGain changes then I have to run the calibration again, is this expected?

If the user changes the tx frequency with LMS_SetLOFrequency when should I perform a calibration again? the input bandwidth is 3.072 MHz (16 x 192kHz), is there a logic / algorithm I can apply to let the user know that the calibration should run again?

FWIW I am watching the output signal with another SDR, the Lime’s 0Hz carrier is now > 60dB down, the signal is clean enough for now :slight_smile: .
