Custom APSK (Digital Demod)
The 89600 provides a format in addition to the standard APSK formats. A unique measurement can be set up using by specifying the quanity and relative magnitude of each ring and the quantity and phase offset of the states on each ring. These configuration parameters are provided in the Custom APSK tab.
The Custom APSK demodulator can be configured to accommodate most APSK signals. It also supports a variety of signals whose constellations are not quite APSK but still described by the four APSK configuration parameters: number of rings, relative magnitude of the rings, number of phase states per ring, and the phase offset of these states.
