SPECTRUM ANALYSER function.
(frequency / amplitude graphical representation of the signals present at the input of the device)
Satellite :
In Satellite mode, remote power control:
On / Off, horizontal / vertical polarization, low / high band
The input attenuator is automatically positioned according to the "Reference Level".
The filter is also automatically positioned according to the "Span".
The value of the filter is indicated at the top of the spectrum
Beware of saturation risks, use the formula:
Input attenuator = Reference level - 60 dBμV.
Example: to correctly display a 110 dBμV signal, you need a 50 dB attenuator
