Hi, I'm going to test the performance of an antenna, but unfortunately the antenna is connected to the receiver front-end and ADC on the board and cannot be separated from the board. So the only way I can read out the signal is to read the data from ADC. Is it possible to convert voltage samples into power(in dBm)? I've seen that some ADCs are able to plot the spectrum(in dBm) using the software interface. I have very poor knowledge about ADC. What does the ADC calibration usually do? (I just heard about this function)
