If the "coding" that is set is not possible with the chosen modulation type, "coding" is set
to "Off".
For selection "Variable FSK", the deviation of each symbol can be set in the "More..."
submenu.
SCPI command:
[:SOURce<hw>]:BB:DM:FORMat on page 567
Load User Mapping - Digital Modulation
Selects user defined mapping table. This opens the "Select List File User Mapping" win-
dow in which the mapping table can be selected (see "User Mapping" on page 286). The
button is only available if modulation type "USER" is selected.
The button "File Manager" calls the "File Manager" menu. The "File" "Manager" menu is
used to display and delete files.
SCPI command:
[:SOURce<hw>]:BB:DM:MLISt:SELect on page 581
[:SOURce<hw>]:BB:DM:MLISt:CATalog on page 573
[:SOURce<hw>]:BB:DM:MLISt:DELete on page 580
ASK Depth - Digital Modulation
Sets the modulation depth m for ASK modulation.
m = (Amplitude
max
-Amplitude
min
) / (Amplitude
max
+Amplitude
min
)
SCPI command:
[:SOURce<hw>]:BB:DM:ASK:DEPTh on page 566
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 568
Angle Alpha
For AQPSK modulation, sets the angle alpha between the point (0,0) and the I axis.
