MPX
The MPX page shows the baseband MPX deviation as a function of deviation in kHz over the
observation period. The graph immediately shows modulation density.
There is also a rolling 60-minute graph of the MPX power with average indicator, measured in
dBr. The MPX Power is calculated continuously with an integration window of 60 seconds and
a new sample every 20 seconds. Therefore, the first sample is available 60 seconds after tuning.
The rule of MPX Power provides to measure the modulation power which is seen equal to
modulate signal electric power, for one minute time period and to compare it to a sinusoidal
modulating signal one which deviates ±19kHz. The result, expressed in dB, must be lower or equal
to zero to comply with the rule.
