7.12.10 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<hw>]:PM[:DEViation]
<Deviation>
The command sets the modulation deviation of the phase modulation in RAD. The max-
imal deviation depends on the RF frequency set and the selected modulation mode (see
data sheet).
The deviation of the internal source must not exceed the deviation of the external source
in case of modulation source "Int+Ext" (
PM:SOURce INT,EXT
).
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
Usage:
SCPI confirmed
[: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.
