326 Operating Manual 1407.0806.32 ─ 21
Parameters:
<DepthExp> float
Range:
-40 to 40
Increment: 0.01
*RST:
10
Example: AM:DEPT:LIN 15PCT
sets the AM modulation depth to 15 percent.
Options: (exponential): R&S SMB-B112/-B112L/-B120/-B120L/-B140/-
B140L
Manual operation: See "AM Depth" on page 200
[: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, Chapter 5.4.2, "Amplitude Modulation
(AM)" , on page 198.
Parameters:
<DepthLin> float
Range:
0 to 100
Increment: 0.1
*RST:
30
Example: AM:DEPT:LIN 15
sets the AM modulation depth to 15 dB.
Manual operation: See "AM Depth" on page 200
[:SOURce<hw>]:AM:EXTernal:COUPling <Coupling>
Selects the coupling mode for the external amplitude modulation signal.
Parameters:
<Coupling> AC | DC
AC
Uses only the AC signal component of the modulation signal.
DC
Uses the modulation signal as it is, with AC and DC.
*RST:
AC
Example: AM:EXT:COUP AC
selects the coupling mode AC for external amplitude modulation.
Manual operation: See "AM External Coupling" on page 201
