290Operating Manual 1411.4060.32 ─ 09
Parameters:
<Deviation> float
Range: 0 to dynamic
Increment: 0.01
*RST: 1E3
Example:
FM:INT1:DEV 2E3
sets 2 kHz deviation for the freqeuncy modulation signal.
Manual operation: See "FM Deviation" on page 174
[:SOURce<hw>]:FM:SENSitivity?
Queries the input sensitivity of the externally applied signal for frequency modulation.
The returned value reports the sensitivity in Hz/V. It is assigned to the voltage value for
full modulation of the input signal.
The sensitivity depends on the set [:SOURce<hw>]:FM[:DEViation].
Return values:
<Sensitivity> float
Range: 0 to max
Increment: 0.01
Example:
FM:DEV 5E3
sets a modulation deviation of 5 kHz.
FM:SENS
queries the input sensitivity at the external modulation input.
Response: 5E3
since the voltage value for full modulation is 1V, the resulting
sensitivity is precisely 5000 Hz/V.
Usage: Query only
Manual operation: See "FM Sensitivity" on page 174
[:SOURce<hw>]:FM:SOURce <Source>
Selects the modulation signal source for frequency modulation.
Parameters:
<Source> INTernal | EXTernal
INT
Uses the internally generated signal for modulation. To configure
the frequency, use the commands of the Chapter 7.13.6,
"SOURce:LFOutput Subsystem", on page 299 subsystem.
EXT
Uses an externally applied modulation signal.
The external signal is input at the MOD EXT connector.
