2. To Set the Invert Waveform
Press Utility → Output Setup → Invert, to set the Inverse Waveform Output.
When the waveform is inverse, no offset will change.
3. 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,
z 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.
z In the Inverse Mode, the Waveform that corresponds to the Sync Signal
does not inverse.
z The Sync Signal is a Pulse Signal with fixed positive pulse width, which is
more than 50ns.
z For non-modulated waveform, the Sync Signal reference is the carrier.
z
For internal modulating AM, FM and PM, the Sync signal reference is the
modulated signal (not the carrier signal).
z For ASK and FSK, the Sync Signal Reference is the keying Frequency.
z
For a Sweep, when the sweep starts, the Sync Signal becomes TTL Level
High. The Sync frequency equals the specific Sweep time.
z For the Burst, when the burst starts, the Sync Signal is Level High.
z
For the External Gated Burst, the Sync Signal follows the External Gated
Signal.
