Phase-Shift Keying (PSK) Modulation
Phase -shift keying (PSK) is a form of digital modulation in
which the phase of the carrier signal is discretely varied.
You can configure the U2761A to “shift” its output phase
between two preset phases using PSK. The rate at which the
output shifts between the two phases is determined by the
internal rate generator on the signal level. The following
figure shows an example of the PSK modulation waveform.

To Select PSK Modulation
The U2761A allows only one modulation mode to be enabled
at a time. The U2761A does not allow PSK to be enabled at
the same time that sweep is enabled.
