In modulation OFF, the output generates continuous Carrier
Waveform frequency. The carrier waveform is sinewave and its
frequency can be programmed using the CW Frequency menu. The
value programmed for the CW Frequency parameter, is used for all
other modulation functions.
The (n)PSK function allows shifts through multiple phase and
amplitude positions to form phase shift constellations. There are 6
different types of phase shift keying that the 2074 can generate:
BPSK, QPSK, OQPSK, pi/4DQPSK, 8PSK and 16PSK. The User
PSK can be used for generating non-standard phase shifts.
