336Operating Manual 1407.0806.32 ─ 13
Parameters:
<Deviation> float
Range: 0 to 20
Increment: See data sheet
*RST: 1
Default unit: RAD
Example:
PM 5
sets the PM modulation deviation to 5 RAD
Manual operation: See "PhiM Deviation" on page 177
[:SOURce<hw>]:PM:EXTernal:COUPling <Coupling>
The command selects the coupling mode for the external modulation input in the case of
phase modulation.
Note: Coupling for external feed via input MOD EXT can be set independently for mod-
ulations FM and PhiM.
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:
PM:EXT:COUP AC
selects the coupling mode AC for external phase modulation.
Manual operation: See "Mod External Coupling" on page 178
[:SOURce<hw>]:PM:EXTernal:DEViation <Deviation>
The command sets the modulation deviation in case of external phase modulation in
RAD. The maximal deviation depends on the RF frequency set and the selected modu-
lation mode (see data sheet).
Parameters:
<Deviation> float
Range: 0 to 20
Increment: See data sheet
*RST: 1
Default unit: RAD
Example:
PM 5
sets the PM modulation deviation for external phase modulation
of 5 RAD.
