[:SOURce<hw>]:FM[:DEViation] <Deviation>
The command sets the modulation deviation of the frequency modulation in Hz. The
maximal deviation depends on the RF frequency set and the selected modulation mode
(see data sheet).
Parameters:
float
0 Hz to 10 MHz
See data sheet
10 kHz
Hz
<Deviation>
Range:
Increment:
*RST:
Default unit:
FM 5E3
sets the FM modulation deviation to 5 kHz.
Example:
SCPI conformUsage:
[:SOURce<hw>]:FM:EXTernal:COUPling <Coupling>
The command selects the coupling mode for the external modulation input (EXT MOD)
in the case of frequency modulation.
Note: Coupling for external feed via input EXT MOD can be set independently for mod-
ulations AM, FM and PhiM.
Parameters:
AC|DC
AC
The DC voltage component is disconnected from the modulation
signal.
DC
The modulation signal is not changed.
<Coupling>
FM:EXT:COUP AC
selects the coupling mode AC for external frequency modulation.
Example:
SCPI conformUsage:
[:SOURce<hw>]:FM:MODE <Mode>
The command selects the mode for the frequency modulation.
