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.
Burst Sync: A square wave that is a TTL high when the burst begins and a TTL low when burst is completed.
Trigger: Selects the current trigger signal. Useful for synchronizing burst or gated signals.

TWO CHANNEL OPERATION (TG5012A & TG2512A only)

The two channels can be operated independently so as to act as entirely separate generators. Alternatively the channels can interact as follows:
Coupled Operation
Coupled Frequency: Frequencies can be coupled such that if frequency of one channel is changed the frequency of the other channel also changes either by a fixed ratio or fixed offset. A pulse waveforms can only be frequency coupled to another pulse waveform, however sine, square, ramp or Arb waveforms can be coupled to any other waveform of that group.
Coupled Level: -Amplitudes (and DC offsets) of the two channels can be coupled such that changing the amplitude and offset on one channel changes the amplitude and offset of both channels.
Coupled On/Off: Coupling can be set such that switching the output on/off on one channel switches the output on/off of both channels.
Tracking Operation
When in tracking mode both channels behave as one channel. If inverse tracking is selected, both channel still behave as one channel except that the output of channel 2 is inverted.
Relative Phase
Pressing the ‘align’ key phase synchronises the two channels with the specified phase offset.
Phase Range: -360.0 to +360.0 degrees
Resolution: 0.1 degree
Skew (typical): <1ns
Cross Channel Trigger
Either channel can be triggered by the other channel to set up a complex and versatile inter channel trigger scheme.
Each channel can have its trigger output waveform set up independently. Trigger Out may be selected to be carrier waveform referenced, modulation waveform referenced, sweep referenced, burst referenced or the currently selected trigger of the channel.
Crosstalk
Channel Crosstalk: Typically better than 80dB
Control and Display
The control of each channel is selected by the Channel Select key.
The display can be assigned either completely to the selected channel, or the upper section can display the main set-up parameters or waveforms for both channels simultaneously.

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: Sine, Square, Ramp, Pulse, Arb
Phase: Range -360.0 to +360.0 degrees
Resolution 0.1 degree
Accuracy < +/-5ns
