[: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 417.
Manual operation: See " Deviation" on page 74
[:SOURce<hw>]:FM<ch>:SOURce <Source>
Selects the modulation source for frequency modulation.
Suffix:
FM<ch>
.
1|2
Modulation signal channel.
Parameters:
<Source> EXT1 | NOISe | LF2 | LF1 | INTernal | EXTernal
LF1|LF2
Uses an internally generated LF signal.
INTernal
Uses the internally generated signal of LF1.
EXTernal
Uses an external LF signal (EXT1).
NOISe
Uses the internally generated noise signal.
*RST: LF1 <FM1>; LF2 <FM2>
Example: See Example"Creating a frequency modulated RF signal"
on page 417.
Manual operation: See "Source" on page 74
