7.13.10 SOURce:PM Subsystem
The PM subsystem contains the commands for checking the phase modulation. The
settings for the internal modulation source (LF generator) are made in the
SOURce:LFOutput subsystem.
For information on the required options, see Chapter 5.4.4, "Phase Modulation (PhiM)",
on page 175.

[:SOURce<hw>]:PM[:DEViation] <Deviation>
Sets the deviation of the phase modulation signals in RAD. 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: 1E-6
Example:
PM 2
sets 2 RAD deviation to the phase modulation signal.
Manual operation: See "ɸM Deviation" on page 176
[:SOURce<hw>]:PM:EXTernal:COUPling <Coupling>
Selects the coupling mode for the external phase 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:
PM:EXT:COUP AC
selects the coupling mode AC for the external phase modulation
signal.
Manual operation: See "PhiM Ext Coupling" on page 177
