Sync Output Signal

A Sync Output is provided on the front-panel Sync output connector on most function generators. All of the standard output functions (except dc and noise) have an associated Sync signal. For certain applications where you may not want to output the Sync signal, you can disable the Sync connector.

Note: Parameter choices vary by instrument. Some of the parameters listed below might not be available on your particular instrument. The bench application will list only those parameters, and parameter ranges, available for your particular instrument.

By default, the Sync signal is routed to the Sync connector (enabled). When the Sync signal is disabled, the output level on the Sync connector is at a logic "low" level.
When a waveform is inverted (see Waveform Polarity), the Sync signal associated with the waveform is not inverted.
For sine, pulse, ramp, square, and triangle waves, the Sync signal is a square wave that is "high" in the first half of the cycle and "low" in the last half. The Sync signal's voltages are TTL-compatible when its load impedance exceeds 1 kΩ.
For arbitrary waveforms, the Sync signal rises at the beginning of the waveform and falls at the middle of the arbitrary waveform.
