This command sets the operating state of the differential data encoding. For a detailed
explanation of differential data encoding, see “

User I/Q Files

The user-defined FSK modulation and user-defined I/Q modulation SCPI commands
contain the differential encoding information. Before designing a differential encoding
scheme, you must first define the FSK or I/Q modulation to be encoded. The actual
differential encoding-related input appears bolded in the command listing above.
This command line enables you to define the differential encoding criteria.
diff state
Toggle for differential encoding. (ON|OFF|1|0)
num diff
states
The number of differential states (0 through 256)
diff0
Value of first differential state (an integer value from -128 t127)
diff1
Value of second differential state (an integer value from -128 through
+127)
