To Set the Sync Output
The generator provides Sync output through the [Sync] connector on the rear
panel. All standard output functions (except DC and Noise) have a
corresponding Sync signal. For some applications, they can be disabled if
users do not want to use it,
In the default setting, the Sync signal should be connected to the [Sync]
connector (activated). When the Sync Signal is disabled, the output
voltage of the [Sync] connector is level low.
In the Inverse Mode, the Waveform that corresponds to the Sync Signal
does not inverse.
The Sync Signal is a Pulse Signal with fixed positive pulse width, which is
more than 50ns.
For non-modulated waveform, the Sync Signal reference is the carrier.
For internal modulating AM, FM and PM, the Sync signal reference is the
modulated signal (not the carrier signal).
For ASK and FSK, the Sync Signal Reference is the keying Frequency.
For a Sweep, when the sweep starts, the Sync Signal becomes TTL
Level High. The Sync frequency equals the specific Sweep time.
For the Burst, when the burst starts, the Sync Signal is Level High.
For the External Gated Burst, the Sync Signal follows the External Gated
Signal.
