[:SOURce<hw>]:FM<ch>[:DEViation] <Deviation>
Sets the modulation deviation of the frequency modulation in Hz.
Suffix:
FM<ch>
.
1|2
Modulation signal channel
Parameters:
<Deviation> float
The maximum deviation depends on the RF frequency and the
selected modulation mode (see data sheet).
Range: 0 to max
Increment: 0.01
*RST: 1E3
Example: See Example "Creating a frequency modulated RF signal"
on page 874.
Manual operation: See "Deviation" on page 508
[:SOURce<hw>]:FM:MODE <Mode>
Selects the mode for the frequency modulation.
Parameters:
<Mode> NORMal | LNOise
NORMal
The maximum range for modulation bandwidth and FM deviation
is available.
LNOise
Frequency modulation with phase noise and spurious character-
istics close to CW mode. The range for modulation bandwidth
and FM deviation is reduced (see data sheet).
*RST: NORMal
