7.12.1 SOURce:AM Subsystem
The AM subsystem contains the commands for checking the amplitude modulation.
The external signal is input at the MOD EXT connector.
The settings for the internal modulation source (LF generator) are made in the
SOURce:LFOutput
subsystem.

[:SOURce<hw>]:AM[:DEPTh]
<Depth>
The command sets the modulation depth of the amplitude modulation in percent. The
modulation depth is limited by the maximum peak envelope power (PEP).
Parameters:
<Depth>
float
Range:
0 to 100
Increment: See data sheet
*RST:
30
Default unit: PCT
Example:
AM 15PCT
sets the AM modulation depth to 15 percent
Usage:
SCPI confirmed
[:SOURce<hw>]:AM:EXTernal:COUPling
<Coupling>
The command selects the coupling mode for the external modulation input in the case of
amplitude modulation.
Parameters:
<Coupling>
AC | DC
AC
The DC voltage component is disconnected from the modulation
signal.
DC
The modulation signal is not changed.
*RST:
AC
Example:
AM:EXT:COUP AC
Selects the coupling mode AC for external amplitude modulation.
Usage:
SCPI confirmed
