4.8 Setting and Operation of Sweep
WF1967/WF1968 4-78
The soft-key [Start] and TRIG key can be used for manual trigger operation.
However, in the case of WF1968, the TRIG key only works on the channel side where the display is
active. For the channel where the display is active,

P.4-20
When only manual trigger operation and remote trigger operation are used for a trigger, set the
trigger source as external [Ext]. Moreover, we recommend that the polarity is set to [Off] to avoid
malfunctions caused by exogenous noise.
l) To start a sweep
In continuous sweep, sweep oscillation mode starts automatically the sweep process. However, if
the sweep setting is not appropriate, the sweep oscillation will not start ([CNFLC] (Conflict) is
displayed in the channel status area). When pressing the soft-key [?] displayed on the left end, the
message concerning an improper setting appears. When that is changed to a proper setting, sweep
oscillation starts.

P.14-8
If sweep is stopped, press the soft-key [Start] to start the sweep. If the soft-key [Start] is not
displayed, press the right end soft-
key [▼2/2] to toggle the soft-key set.
In case of single sweep or gated single sweep, when a trigger is accepted, the sweep is started.
However, if the sweep setting is not appropriate, trigger cannot be received ([CNFLC] (conflict) is
displayed in the channel status area). When pressing the soft-key [?] displayed on the left end, the
message concerning an improper setting appears. When it is changed to the correct setting, a trigger
can be accepted.

P. 14-8
The soft-key [Start] and the manual trigger key on the panel operate as manual trigger operation,
regardless of the trigger source setting.
m) To pause sweep
When the soft-key [Stop] is pressed while sweep is running, the sweep stops and enter the state to
output a sweep starting value (not stop value). If the soft-key [Stop] is not displayed, press the right
end soft-
key [▼2/2] to toggle the soft-key set. However, in case of single sweep or gated single
sweep, when a new trigger is accepted, the sweep is started again.
n) To pause sweep temporarily
When pushing [Hold] soft-key while a sweep is executed, the sweep is paused. Afterwards, when
the soft-key [Resume] is pushed, the sweep is restarted at the point where it is paused. If the
soft-key [Hold] or [Resume] is not displayed, press the right end soft-
key [▼2/2] to toggle the
soft-key set.
However, in case of single sweep or gated single sweep, when a new trigger is accepted during
being held, the sweep is started from the beginning.
The soft-key [Hold] and [Resume] are displayed as [Hold] during sweep, and as [Resume] during
pause, at the same position.
o) To output sweep starting value
When the soft-key [SttState] is pressed, it enters into the status to output the sweep starting value.
You can check the status of tested equipment with sweep starting value.
The soft-key [SttState] is displayed in the status to output the sweep stop value. If the soft-key
[SttState] is not displayed, press the right end soft-key
[▼2/2] to toggle the soft-key set.
In case of gated single sweep, it is in oscillation status with starting value. To stop the oscillation,
press the soft-key [Stop].
