D8PSK (Digital Demod)

Menu Path: MeasSetup > Digital Demod Properties > Format tab > Format: box 

Differential 8-Phase Shift Keying (D8PSK) is a differential modulation format where the bits for a given symbol are determined by the phase change from the previous symbol.

There are four possible phase state transitions (+/- (pi/6), +/- (pi/3), +/- (2pi/3), and +/- (5pi/6) radians) therefore each symbol represents log₂(8) = 3 bits of data.

The constellation diagram is the same for 8PSK.
