R&S SMC100A Command Description
1411.4060.32 6.31 E-1
SOURce Subsystem
The SOURce subsystem contains the commands for configuring the generated signals. The keyword
SOURce is optional and can be ommitted.
SOURce:AM Subsystem
The AM subsystem contains the commands for checking the amplitude modulation. The AM-specific
characteristics of the internal modulation source are defined with commands SOURce:AM:INTernal:...
Characteristics which are valid for all modulations and the LF Output are configured in the
SOURce:LFOutput subsystem. The external signal is input at the MOD EXT connector.
The keyword SOURce is optional with commands and can be omitted.
Command Parameters Default unit Remark
[SOURce:]AM[:DEPTh] 0...100 PCT PCT
[SOURce:]AM:EXTernal:COUPling AC | DC
[SOURce:]AM:SENSitivity? Query only
[SOURce:]AM:SOURce EXT | INT
[SOURce:]AM:STATe ON | OFF
[SOURce:]AM[:DEPTh] 0 ... 100 PCT
The command sets the overall modulation depth of the amplitude modulation in percent.
Example:
AM 15PCT
'sets the AM modulation depth to 15 percent.
*RST value Resolution Options SCPI
30 PCT See data sheet Compliant
[SOURce:]AM:EXTernal:COUPling AC | DC
The command selects the coupling mode for the external modulation input (MOD EXT) in the case of
amplitude modulation.
Parameters: AC
The DC voltage component is disconnected from the modulation signal.
DC
The modulation signal is not changed.
Example:
AM:EXT:COUP AC
'selects the coupling mode AC for external amplitude modulation
*RST value Resolution Options SCPI
AC - Compliant
