4.8 Sweep Setting and Manipulation
89
WF1973/WF1974
Single-shot shuttle sweep
j) To output the waveform only during sweep execution → Gated single-shot
sweep
Set [SwpMode] (sweep mode) on the 2nd page of the setting screen to [Gated] (gated single-
shot). This operation combines gated oscillation and sweep, with sweep execution in
synchronization with a trigger.
Since a trigger signal is required, set the trigger signal with [Trig] (trigger) on the 2nd page.
For the trigger setting procedure, ) p. 90.
■ Oscillation start/stop phase
The oscillation start/stop phase setting is done with [Phase] (phase) on the 1st page of the
setting screen.
However, during phase sweep, the start phase setting is the oscillation start phase, and the
stop phase setting is the oscillation stop phase.
■ Stop level (normally set to [Off])
To set the level while the oscillation is stopped separately from the phase, set [StpLvl] (stop
level) on the 3rd page of the setting screen to [On] (on) and set the level with a % value using
the amplitude full scale as reference. Normally, [Off] (off) is set. When [Off] is selected, the
signal level while oscillation is stopped is determined by the phase set in [Phase] on the 1st
page of the setting screen. For details on the stop level, ) p. 112.
■ Oscillation stop unit (normally set to [Cycle] (1 cycle))
To stop oscillation in half-cycle units, set [OscStop] (oscillation stop unit) on the 3rd page of
the setting screen to [HalfCycle] (half cycle). Normally, set to [Cycle] (1 cycle). When [Cycle]
(1 cycle) is set, whole integer cycle oscillation results.
When oscillation is stopped, it always stops either in 1-cycle or half-cycle units according to
the [OscStop] (oscillation stop unit) setting, and the oscillation time is usually longer than
the sweep time setting.
