[:SOURce<hw>]:FM:EXTernal:DEViation <Deviation>
The command enters the deviation of the external FM signal The deviation of the internal
source must not exceed the deviation of the external source in case of modulation source
Int+Ext.
Parameters:
<Deviation> float
Range: 0 to 40 MHz
*RST: 1kHz
Default unit: Hz
Example:
FM:EXT:DEV 3kHz
sets an external modulation depth of 3 kHz
[:
SOURce<hw>]:FM:INTernal:DEViation <Deviation>
The command selects the deviation for the frequency modulation signals. The sum of the
two values must not exceed the overall modulation deviation set with command
SOURce:FM:DEViation.
Parameters:
<Deviation> float
Range: 0 to max
*RST: 0.5 RAD
Example:
PM:INT1:DEV 10RAD
selects a deviation of 10 RAD for the LF generator.
[:SOURce<hw>]:FM:MODE <Mode>
The command selects the mode for the frequency modulation.
Parameters:
<Mode> NORMal
NORMal
The maximum range for modulation bandwidth and FM deviation
is available.
HDEViation
Frequency modulation with full setting range for FM deviation. The
range for modulation bandwidth is reduced (see data sheet).
*RST: NORMal
Example:
FM:MODE NORM
selects normal mode for external frequency modulation.
Manual operation: See "FM Mode" on page 174
