697User Manual 1178.4460.02 ─ 03
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 694.
Manual operation: See "Deviation" on page 353
[: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 694.
Manual operation: See "Source" on page 353
[:SOURce<hw>]:FM:DEViation:MODE <FmDevMode>
Selects the coupling mode. The coupling mode parameter also determines the mode
for fixing the total deviation.
Parameters:
<FmDevMode> UNCoupled | TOTal | RATio
UNCoupled
Does not couple the LF signals.
The deviation values of both paths are independent.
TOTal
Couples the deviation of both paths.
