LMS_Calibrate Fails at Low Frequencies


When I try to use the LMS_Calibrate function at lower center frequencies, for instance, in the 40-60MHz, it requires me to set the TX and RX antennas gains to almost their maximum value otherwise the function will fail, indicating me: “MCU error 5 (Loopback signal weak: not connected/insufficient gain?)”. However I can call the same function at much higher center frequencies with much lower gains.

Unfortunately for my application, I would require the use of lower antenna gains in the 40-60MHz range. Can someone explain to me how the LMS_Calibrate function works or maybe explain to me how can I manually perform the same calibrations at the 40-60MHz range so that I can operate with lower antennas gains?

Thanks in advance.
