4. BASIC OPERATION
MULTIFUNCTION GENERATOR
■ When [BrstSync] is selected
A TTL level signal synchronized with the gate oscillation is output from the sync/sub-output
terminal. As shown in the following figure, this signal is low during oscillation and high
during oscillation stop. Note that this differs from the gate signal.
When the signal during burst is observed with an oscilloscope, it can be used as the trigger
signal for the oscilloscope.
i) To execute oscillation in half-cycle units → Set oscillation stop unit to half cycle
To stop oscillation in half-cycle units, set [OscStop] (oscillation stop unit) on the 2nd page of
the setting screen to [HalfCycle] (half cycle). Normally [Cycle] (1 cycle) is set. When [Cycle]
(1 cycle) is set, oscillation is done in integer cycles.
The next figure compares oscillation done using 1 cycle and half cycle as the oscillation stop
unit, under the following conditions: oscillation start/stop phase = 30°, stop level = off.
In the case of 1-cycle units, following gate off, oscillation stops once the oscillation start/stop
phase is reached.
In the case of the half-cycle unit, following gate off, the oscillation stops once the oscillation
start/stop phase or [oscillation start/stop phase + 180° (or − 180°)] is reached, and then the
oscillation start/stop phase is transited to.
j) Usage of stop level
The level when oscillation is stopped is normally set with the oscillation start/stop phase,
but it can also be set independently from that with a proportion of the amplitude full scale.
Set [StpLvl] (stop level) on the 2nd page of the setting screen to [On] (on) and set the level
with a % value. ) p. 112
