"High Deviation"
The maximum range for PhiM deviation is available.
Phase noise is improved for low frequencies compared to the default
mode. The range for modulation frequency is limited (see data sheet).
This mode is suitable for low modulation frequencies and/or high
PhiM deviation.
"Low Noise"
Frequency modulation with phase noise and spurious characteristics
close to CW mode. The range for modulation bandwidth and FM devi-
ation is reduced (see data sheet).
Remote command:
AM settings
The following settings are dedicated to AM.
AM Depth ← AM settings
Determines the depth of the modulation signal in percent.
The depth is limited by the maximum peak envelope power (PEP).
Remote command:
Ratio Path2/Path1 ← AM settings
Sets the deviation ratio (path2 to path1) in per cent.
Remote command:
4.4.3 Pulse Generator
