Command Description R&S SMC100A
1411.4060.32 6.60 E-1
[SOURce:]PM:EXTernal[:DEViation] 0 ... 160 RAD
The command sets the modulation deviation in case of external phase modulation in RAD. The
maximal deviation depends on the RF frequency set and the selected modulation mode (see data
sheet).
Example:
PM 5E3
'sets the PM modulation deviation for external phase modulation of 5 RAD.
*RST value Resolution Options SCPI
1 RAD See data sheet Compliant
[SOURce:]PM:SENSitivity?
The command queries the input sensitivity of the MOD EXT input in RAD/V. The command is only
effective if the external modulation source is selected (SOUR:PM:SOUR EXT). The returned value
depends on the modulation deviation setting (SOUR:PM:DEViation). This value is assigned to the
voltage value for full modulation of the input.
The command is a query command and therefore has no *RST value.
Example:
PM:DEV 1
'sets a modulation deviation of 1RAD.
PM:SENS?
'queries the input sensitivity at the EXT MOD input.
Response: 1
'since the voltage value for full modulation is 1V, the resulting sensitivity is
precisely 1RAD/V.
*RST value Resolution Options SCPI
- - Compliant
[SOURce:]PM:SOURce EXT | INT
The command selects the modulation source for phase modulation. INT is the internal modulation
source which is configured in the SOURce:LFOutput subsystem. The external analog signal is input
at the MOD EXT connector."
Example:
PM:SOUR INT
'selects the internal modulation source.
*RST value Resolution Options SCPI
INTernal - Compliant
[SOURce:]PM:STATe ON | OFF
The command activates/deactivates phase modulation.
Activation of phase modulation deactivates frequency modulation.
Example:
PM:STAT ON
'activates PM modulation.
*RST value Resolution Options Correlation SCPI
OFF -
PM:STATe ON deactivates frequency
modulation.
Compliant
