R&S SMC100A Frequency Modulation - FM
1411.4060.32 4.85 E-4
FM Sensitivity
(Source External only)
Displays the input sensitivity of the MOD EXT input in Hz/V. The
display only appears in the case of external modulation.
The modulation depth entered under FM Depth is reached with 1 Volt
modulation of the input.
Note:
The input voltage should not exceed 1.1 V
s
, otherwise modulation
distortions might occur.
Remote-control command:
SOUR:FM:SENS? Response: "1E3"
Adjust FM Offset
Starts the adjustment for the FM/PhiM modulator. The option is
adjusted with respect to DC-offset.
Remote-control command:
CAL:FMOF
CAL:FMOF?
Mod 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.
AC
The d.c. voltage content is separated from the
modulation signal.
Remote-control command:
SOUR:FM:EXT:COUP AC
DC
The modulation signal is dc-coupled.
Remote-control command:
SOUR:FM:EXT:COUP DC
LF Gen Freq - FM
(Source Internal)
Sets the frequency of the LF generator.
Remote-control command:
SOUR:LFO:FREQ 1E3
