[: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:
<Deviation> float
Range: 0 Hz to 10 MHz
Increment: See data sheet
*RST: 10 kHz
Default unit: Hz
Example:
FM 5E3
sets the FM modulation deviation to 5 kHz.
Manual operation: See "FM Deviation" on page 174
[:SOURce<hw>]:FM:EXTernal:COUPling <Coupling>
The command selects the coupling mode for the external modulation input in the case of
frequency modulation.
Parameters:
<Coupling> AC | DC
AC
The DC voltage component is disconnected from the modulation
signal.
DC
The modulation signal is not changed.
*RST: AC
Example:
FM:EXT:COUP AC
selects the coupling mode AC for external frequency modulation.
Manual operation: See "FM External Coupling" on page 175
