Parameters:
<Mode> HDEViation | HBANdwidth
HDEViation
Provides full setting range of PhiM deviation. The range of mod-
ulation frequency is limited (see data sheet). Recommended for
low modulation frequencies and/or high PhiM deviation.
HBANdwidth
Provides maximum range of modulation bandwidth. Recommen-
ded for high modulation frequencies.
*RST:
HBANdwidth
Example: PM:MODE LNO
selects Low Noise mode for external phase modulation.
Manual operation: See "
ɸ
M Mode" on page 250
[:SOURce<hw>]:PM:SENSitivity?
Queries the input sensitivity of the externally applied signal for phase modulation. The
returned value reports the sensitivity in RAD/V. It is assigned to the voltage value for
full modulation of the input.
Return values:
<Sensitivity> float
Example: PM:DEV 1
sets a modulation deviation of 1RAD.
PM:SENS?
queries the input sensitivity at the external modulation input.
Response: 1
since the voltage value for full modulation is 1V, the resulting
sensitivity is precisely 1RAD/V.
Usage: Query only
Manual operation: See "
ɸ
M Sensitivity" on page 251
[:SOURce<hw>]:PM:SOURce <Source>
Selects the modulation signal source for phase modulation.
You can use both, the internal and an external modulation signal at a time.
