Command Description R&S SMC100A
1411.4060.32 6.32 E-1
[SOURce:]AM:SENSitivity?
The command queries the input sensitivity of the MOD EXT input in %/V. The command is only effective
if the external modulation source is selected (SOUR:AM:SOUR EXT). The returned value depends on the
modulation depth setting (SOUR:AM:DEPTh). 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:
AM:DEPT 50
'sets a modulation depth of 50 %.
AM:SENS?
'queries the input sensitivity at the MOD EXT input.
Response: 50
'since the voltage value for full modulation is 1V, the resulting sensitivity is
precisely 50%/V.
*RST value Resolution Options SCPI
- - Compliant
[SOURce:]AM:SOURce EXT | INT
The command selects the modulation source for amplitude modulation. INT is the internal
modulation source and is configured in the SOURce:LFOutput subsystem. The external signal is
input at the MOD EXT connector.
Example:
AM:SOUR INT
'selects the internal modulation source.
*RST value Resolution Options SCPI
INTernal - Compliant
[SOURce:]AM:STATe ON | OFF
The command activates/deactivates amplitude modulation.
Example:
AM:STAT ON
'activates AM modulation.
*RST value Resolution Options SCPI
OFF - Compliant
