Parameters:
<Time> 0 s to measurement time
*RST: 0 s
Example:
ADEM:PM:RPO 500us
Sets the position where the phase to 0 rad setting to 500 µs.
Usage: SCPI confirmed
Manual operation: See "Zero Phase Reference Position (PM Time Domain only)"
on page 110
[SENSe:]ADEMod:SQUelch[:STATe] <State>
This command activates the squelch function, i.e. if the signal falls below a defined
threshold (see [SENSe:]ADEMod:SQUelch:LEVel on page 256), the demodulated
data is automatically set to 0.
Parameters:
<State> ON | OFF
*RST: OFF
Example:
DEM:SQU ON
Signals below the level threshold are squelched.
Manual operation: See "Squelch State" on page 108
[SENSe:]ADEMod:SQUelch:LEVel <Threshold>
This command defines the level threshold below which the demodulated data is set to
0 if squelching is enabled (see [SENSe:]ADEMod:SQUelch[:STATe] on page 256).
Parameters:
<Threshold> numeric value
The absolute threshold level
Range: -150 dBm to 30 dBm
*RST: -40 dBm
Example:
DEM:SQU:LEV -80
If the signal drops below -80 dBm, the demodulated data is set
to 0.
Manual operation: See "Squelch Level" on page 108
