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: See Example "Performing phase modulation" on page 577.
Usage: Query only
[:SOURce]:PM<ch>[:DEViation] <Deviation>
Sets the modulation deviation of the phase modulation in RAD.
Parameters:
<Deviation> float
The maximal deviation depends on the RF frequency and the
selected modulation mode (see data sheet).
Range: 0 to max
Increment: 1
*RST: 1
Default unit: RAD
Example: See Example "Performing phase modulation" on page 577.
Manual operation: See "Deviation" on page 89

Pulse modulation settings
With the commands described in this section, you can configure the settings for pulse
modulation, select the trigger mode and determine delay times for the pulse modula-
tion signal.
Example: Perform pulse modulation
The example shows a command sequence to perform pulse modulation.
// Reset the instrument to start from an initial state
*RST; *CLS
// Set the RF signal frequency and level
