289Operating Manual 1411.4060.32 ─ 09
Parameters:
<Deviation> float
Range: 0 to dynamic
Increment: 0.01
*RST: 1000
Example:
FM 2E3
sets a 2 kHz deviation to the modulation signal.
Manual operation: See "FM Deviation" on page 174
[:SOURce<hw>]:FM:EXTernal:COUPling
<Coupling>
Selects the coupling mode for the external frequency 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:
FM:EXT:COUP AC
selects the coupling mode AC for the external frequency modu-
lation signal.
Manual operation: See "FM External Coupling" on page 174
[:SOURce<hw>]:FM:EXTernal:DEViation <Deviation>
Sets the deviation of the external frequency modulation signal in Hz. The maximum
deviation depends on the set RF frequency and the selected modulation mode (see
data sheet).
Parameters:
<Deviation> float
Range: see data sheet
Increment: 0.01
*RST: 1000
Example:
FM:EXT:DEV 3kHz
sets 3 kHz deviation to the frequency modulation signal.
Manual operation: See "FM Deviation" on page 174
[:SOURce<hw>]:FM:INTernal:DEViation <Deviation>
Sets the deviation of the internal frequency modulation signal in Hz.
