LF1|LF2
Uses an internally generated LF signal.
INTernal = LF1
Works like LF1
EXTernal
Works like EXT1
EXT1|EXT2
Uses an externally supplied LF signal.
NOISe
Uses the internally generated noise signal.
*RST:
LF1 <FM1>; LF2 <FM2>
Example: See Example "Creating a frequency modulated RF signal"
on page 572.
Manual operation: See "Source" on page 87
[: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.
RATio
Couples the deviation ratio of both paths
*RST: UNCoupled
Example: See Example "Using combined LF signals" on page 572.
Manual operation: See " Deviation Mode" on page 88
[:SOURce<hw>]:FM:DEViation:SUM <FmDevSum>
Sets the total deviation of the LF signal when using combined signal sources in fre-
quency modulation.
Parameters:
<FmDevSum> float
Range: 0 to 40E6
Increment: 0.01
*RST: 1E3
Example: See Example "Using combined LF signals" on page 572.
