between carrier phase and modulation phase is determined by the specified PSK
frequency.
When the external modulation is selected, PSK frequency cannot be adjusted and is
determined by the signal level on the rear-panel [Ext Trig] connector. When a logic high
level is present, the carrier phase is output. With a logic low level, the modulation phase
is output.
The carrier wave for PSK modulation can be set with the function keys
of
on the front panel.
