ASK Depth
Sets the modulation depth m for ASK modulation.
m = (Amplitude
max
-Amplitude
min
) / (Amplitude

)
Remote command:
[:SOURce<hw>]:BB:DM:ASK:DEPTh on page 1000
FSK Deviation
Sets the frequency deviation for FSK modulation. The range of values depends on the
selected Symbol Rate (see data sheet).
Whenever "MSK" is selected, the deviation corresponds to 1/4 of the symbol rate and
cannot be changed.
Remote command:
[:SOURce<hw>]:BB:DM:FSK:DEViation on page 1000
Angle Alpha
For AQPSK modulation, sets the angle alpha between the point (0,0) and the I axis.
Remote command:
[:SOURce<hw>]:BB:DM:AQPSk:ANGLe on page 999
FSK Type
For "Variable FSK", selects the FSK modulation type.
Available are 4FSK, 8FSK and 16FSK.
Remote command:
[:SOURce<hw>]:BB:DM:FSK:VARiable:TYPE on page 1001
Deviation xxxx
For "Variable FSK", sets the deviation of the associated symbol. The number of sym-
bols depends on the selected modulation type. The value of each symbol is indicated
in binary format, i.e. x can be 1 or 0.
