SCPI command:
[:SOURce<hw>]:BB:DM:ASK:DEPTh on page 639
FSK Deviation - Digital Modulation
Sets the frequency deviation for FSK modulation. The range of values depends on the
chosen symbol rate (see data sheet).
Whenever "MSK" is selected, the deviation corresponds to 1/4 of the symbol rate and
cannot be set.
SCPI command:
[:SOURce<hw>]:BB:DM:FSK:DEViation on page 641
Angle Alpha
For AQPSK modulation, sets the angle alpha between the point (0,0) and the I axis.
SCPI command:

More - Modulation Type - Digital Modulation
Calls the submenu which displays the mapping of the currently selected modulation type
and the digital modulation delay in the case of an external data source.
The "Modulation - CW Switching" section can be used to enable switching of the signal
between modulated and unmodulated.
