Phase Shift Keying (PSK)
What the settings
are for
Phase shift keying is a phase modulation ( 6-122) for digital signals. With
this method the signal has a constant frequency and a constant amplitude.
The phase position of the output signal changes abruptly in step with the
digital modulation signal. In this method the digital value "0" is assigned to
one phase position, e.g. 0 degrees, and digital "1" is assigned to the other
phase position, e.g. 180 degrees.
You can use the FSK MOD submenu to set the PSK modulation signal,
modulation frequency and phase shift.
