CHAPTER 4: Operation
Amplitude
If the BNC input is selected, the voltage of the MADI carrier is measured. Using
the SFP input the module’s DDM* signalling is utilized. The analysis results are
indicated by ‘traffi c light’ leds.

NOTE!
The AES10 spec requires the voltage of the carrier to be between 300..600 mV.
NOTE
It is advised to perform the calibration of the BNC I/O at periodic intervals - see
page 33.
