Phase Modulation - PhiM R&S SMB
1407.0806.32 4.70 E-2
Ext
Selects the external source for analog phase
modulation. The external signal is input via the MOD
EXT connector.
Remote-control command:
SOUR:PM:SOUR EXT
Int + Ext
Selects the internal and external source at the same
time. The external signal is input via the MOD EXT
connector.
Remote-control command:
SOUR:PM:SOUR INT,EXT
PhiM Mode
Selects the mode for the phase modulation..
Normal
The full range for modulation bandwidth and PM
deviation is available.
Remote-control command:
SOUR:PM:MODE NORM
High Deviation
The maximum range for PhiM deviation is available.
Phase noise is improved for low frequencies
compared to Normal mode. The range for
modulation frequency is limited (see data sheet).
This mode is recommended for low modulation
frequencies and high PhiM deviation.
Remote-control command:
SOUR:PM:MODE HDEV
Low Noise
Phase modulation with phase noise and spurious
characteristics close to CW mode. The range for
modulation bandwidth and PM deviation is reduced
(see data sheet).
Remote-control command:
SOUR:PM:MODE LNO
PhiM Deviation
Sets the modulation deviation in RAD.
The maximal deviation depends on the RF frequency set and the
selected modulation mode (see data sheet). It is possible to enter a
deviation that is too high for a certain RF frequency or to vary the RF
frequency to a range in which the deviation can no longer be set. In
this case the maximally possible deviation is set and an error
message is displayed.
Remote-control command:
SOUR:PM:DEV 2.5
SOUR:PM:EXT:DEV 2.5
