289Operating Manual 1407.0806.32 ─ 13
Example:
AM:DEPT:LIN 15PCT
sets the AM modulation depth to 15 percent.
Options: (exponential): R&S SMB-B112/112L/120/120L/140/140L
Manual operation: See "AM Depth" on page 170
[: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 amplitude
modulation with command [:SOURce<hw>]:AM:TYPE. In this case, the generator sets
modulation depth in dB (logarithmic).
For more details, see also the GUI reference, chapter 5.4.2, "Amplitude Modulation
(AM)", on page 169.
Parameters:
<DepthLin> float
Range: 0 to 100
Increment: 0.01
*RST: 30
Example:
AM:DEPT:LIN 15
sets the AM modulation depth to 15 dB.
Manual operation: See "AM Depth" on page 170
[: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.
Manual operation: See "AM External Coupling" on page 172
