711 Operating Manual 1403.7458.32 ─ 14
Parameters:
<Mode> NORMal
NORMal
Provides full setting range of modulation bandwidth and FM
deviation.
*RST:
NORM
Example: FM:MODE NORM
selects normal mode for external frequency modulation.
Manual operation: See "FM Mode" on page 247
[: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 247
[:SOURce<hw>]:FM:SOURce <Source>
Selects the modulation signal source for frequency modulation.
You can use both, the internal and an external modulation signal at a time.
