    Sync Out

    Multifunction output user definable or automatically selected to be any of the following:

    Carrier Waveform Sync: Sine/Ramp/Pulse - A square wave with 50% duty cycle at the waveform frequency.

    Square - A square wave with same duty cycle as the main output at the waveform frequency.

    Arbs - A square wave with 50% duty cycle at the waveform frequency. The sync is a TTL high when the first point of the waveform is output. Noise - No sync associated with noise.

    Modulation Sync: AM/FM/PM/PWM A square wave with 50% duty cycle referenced to the internal modulation waveform when modulation source is internal, or a square wave referenced to the carrier waveform when modulation source is external. No sync is associated with noise as the modulation source.

    FSK - A square wave referenced to the trigger rate. The sync is a TTL high when hop frequency is the output frequency and TTL low when carrier frequency is the output frequency for positive slope and vice versa for negative slope.

    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.
