Note: Coupling for external feed via input FM/PM EXT can be set independently for
modulations PM 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.
Usage: SCPI confirmed
[:SOURce<hw>]:PM:MODE <Mode>
The command selects the mode for the phase modulation.
Parameters:
<Mode> HBANdwidth | HDEViation | LNOise
HBANdwidth
The maximum range for modulation bandwidth is available. How-
ever, phase noise is increased for low frequencies. The range for
PhiM deviation is limited. This mode is recommended for high
modulation frequencies.
HDEViation
The maximum range for PhiM deviation is available. Phase noise
is improved for low frequencies. The range for modulation fre-
quency is limited (see data sheet). This mode is recommended for
low modulation frequencies and/or high PhiM deviation.
LNOise
Phase modulation with phase noise and spurious characteristics
close to CW mode. The range for modulation bandwidth and PM
deviation is limited (see data sheet)
*RST:
HBANdwidth
Example:
PM:MODE LNO
selects Low Noise mode for external phase modulation.
Usage: SCPI confirmed
