ASK Depth
Sets the modulation depth m for ASK modulation.
m = (Amplitude
max
-Amplitude
min
) / (Amplitude
max
+Amplitude
min
)
Remote command:
[:SOURce<hw>]:BB:DM:ASK:DEPTh on page 901
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 901
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 901
FSK Type
(Variable FSK only)
Selects the FSK modulation type for selection "Variable FSK".
Available are 4FSK, 8FSK and 16FSK.
Remote command:
[:SOURce<hw>]:BB:DM:FSK:VARiable:TYPE on page 902
Deviation xxxx
(Variable FSK only)
Sets the deviation of the associated symbol. The number of symbols depends on the
selected modulation type. The value of each symbol is indicated in binary format.
Remote command:
[:SOURce<hw>]:BB:DM:FSK:VARiable:SYMBol<ch0>:DEViation on page 902
