Phase Synchronising Two Generators
Two generators can be synchronised together to provide outputs at the same frequency (or
harmonics) and with a phase difference. The amplitude and phase of these outputs can also be
modulated providing the capability to perform QAM and QPSK respectively. It is also possible to
synchronise more than two generators but results are not guaranteed.
Carrier Waveforms:
Phase:
(except Pulse
& PRBS)
Marker Off
A square wave that is a TTL high from the beginning of the
sweep and a TTL low from the midpoint of the sweep
Marker On
A square wave that is a TTL high from the beginning of the
sweep and a TTL low from the marker frequency

Nominally 3V logic level from 50
