Amplitude Modulation - AM R&S SMB
1407.0806.32 4.64 E-2
AM Sensitivity
(Source External only)
Displays the input sensitivity of the MOD EXT input in %/V. The
display only appears in the case of external modulation.
The modulation depth entered under AM Depth is reached with 1 Volt
modulation of the input.
Remote-control command:
SOUR:AM:SENS?
Response: "30"
AM Ext Coupling
(Source External only)
Selects the coupling mode (AC or DC) for external feed.
Note:
Coupling for external feed via input MOD EXT is set for all
modulations with external source.
Remote-control command:
SOUR:AM:EXT:COUP AC
In case of selection Source Int, the settings for the internal modulation sources are offered in the AM
Source = INTernal section of the Amplitude Modulation menu. These settings affect all analog
modulations which use the same modulation sources.
LF Gen Freq - AM
(Source Internal)
Sets the frequency of the LF generator.
Remote-control command:
SOUR:LFO:FREQ 1E3
LF Gen Shape - AM
(Source Internal)
Selects the shape of the LF generator signal.
Remote-control command:
SOUR:LFO:SHAP SIN
