How to Simply Generate a PSK Modulation 

Phase-Shift Keying (PSK) 

is a

 

technique used to transmit data by modifying the phase of a sinusoid carrier 

wave. Tabor Arbitrary Waveform Generators (AWGs) supports PSK modulation according to the following 
variations:  PSK, BPSK, QPSK, OQPSK, pi/4DQPSK, 8PSK, 16PSK, as well as user-defined variations.

 

This 

document will quickly guide you through the definition process as shown on a WW2572A. 

NOTE 

You can also generate 

Quadrature Amplitude Modulation (QAM)

 by following steps similar to those described in this document.  

The (n)PSK and (n)QAM modulations are available

 in the 

WW2572A, WW5064/1074/2074, WS8102 and PM8572A models. 

The front panel of the AWG is depicted below.
