Carrier Sync:
A square wave at the same frequency and duty as the carrier waveform.
Available for all waveforms except noise.
Modulation Sync:
A square-wave at the same frequency as the internal modulation waveform
with a duty of 50%. Not available for external modulation.
Sweep Sync:
Outputs the sweep trigger and sweep marker signals.
Burst Sync:
A square wave coincident with a burst output.
Trigger:
A buffered version of the Trigger signal.

Inversion is also possible using the +/– key as described in the Continuous Carrier Waveform
Operation section.
