R&S SMB100A
Parameters:
<DepthExp>
Example:
Options:
Manual operation:
[:SOURce<hw>]:AM:DEPTh:LINear <DepthLin>
Sets the overall modulation depth of the amplitude modulation in percent.
Note: For high frequency instruments, you can alternatively select exponential ampli-
tude modulation with command [:SOURce<hw>]:AM:TYPE. In this case, the genera-
tor sets modulation depth in dB (logarithmic).
For more details, see also the GUI reference,
(AM)",
Parameters:
<DepthLin>
Example:
Manual operation:
[:SOURce<hw>]:AM:EXTernal:COUPling <Coupling>
Selects the coupling mode for the external amplitude modulation signal.
Parameters:
