254Operating Manual 1176.8016.02 ─ 17
State
Activates frequency modulation.
Activation of FM deactivates phase modulation.
Remote command:
[:SOURce<hw>]:FM:STATe on page 734
FM Source
Selects the source for the FM signal.
"Internal"
Uses the internal LF generator as modulation signal source for FM.
"External"
Uses an externally applied modulation signal.
The external signal is input via the EXT MOD connector.
"Internal + External"
Uses both, the internal and externally applied modulation signal, for
example to perform two-tone FM.
Remote command:
[:SOURce<hw>]:FM:SOURce on page 733
FM Mode
Selects the mode for the frequency modulation.
"Normal"
The maximum range for modulation bandwidth and FM deviation is
available.
"Low Noise"
Frequency modulation with phase noise and spurious characteristics
close to CW mode. The ranges of modulation bandwidth and FM
deviation are reduced (see data sheet).
"High Deviation"
Frequency modulation with full setting range for FM deviation. The
range of modulation bandwidth is reduced (see data sheet).
Remote command:
[:SOURce<hw>]:FM:MODE on page 732
