SMBV100A
590 Operating Manual 1176.8016.02 ─ 17
Parameters:
<Depth> float
Range:
0 to 100
Increment: See data sheet
*RST:
30
Example: AM 15PCT
sets the 15% AM modulation depth
Manual operation: See "AM Depth" on page 252
[: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 252
[:SOURce<hw>]:AM:SENSitivity?
Queries the input sensitivity of the externally applied signal for amplitude modulation.
The sensitivity depends on the set modulation
[:SOURce<hw>]:AM[:DEPTh]
.
The returned value reports the sensitivity in %/V. It is assigned to the voltage value for
full modulation of the input.
Return values:
<Sensitivity> float
Range:
0 to 100
Example: AM:DEPT 50
sets a modulation depth of 50 %.
AM:SENS?
queries the input sensitivity at the external modulation input.
Response: 50
since the voltage value for full modulation is 1V, the resulting
sensitivity is precisely 50 %/V.
Usage: Query only
Manual operation: See "AM Sensitivity" on page 252
