Amplitude
If the BNC input is active, the voltage of the MADI carrier is measured. The AES10
spec requires it to be between 300..600mV.

For the SFP input, the RX power measurement of the SFP module is read out and
displayed in the same fashion as for the BNC input. If the SFP module has no DDM
capabilities, the ‘AMPLITUDE’ led blinks to indicate that this parameter cannot be
measured.
