11.4 Setting and Operation Procedure
WF1967/WF1968 11-16
j) Returning to normal oscillation mode
Select other than [Sequence] (such as [Oscillator]) in the top menu and then press the ENTER key.
The dialog to confirm the exit from the sequence oscillation mode is displayed. Select [OK] and
then press the ENTER key. This switches back to the normal oscillation mode.
In the sequence oscillation mode, displaying the other items of the top menu means switching to the
normal oscillation mode.
k) Controlling the start, stop, and pause of the sequence by using an external logic
signal
When the external control [ExtCtrl] in the common setting is set to [Enable], the sequence operation
can be performed by the TTL level logic input to the multi-I/O connector on the rear panel.
☞
P.11-11
It is recommended that this be set to [Disable] when not using an external control signal in order to
avoid malfunctions caused by exogenous noise.
For the multi-I/O connectors and their pin allocation,
☞
P.3-15
During the external trigger input (BNC terminal), only the sequence start operation can be
performed.
☞
P.11-11
The following operations are available:

Starting a sequences
Falling input in the [Rdy] status stars a sequence. This is disabled in the [Run] or [Hold] status.

Stopping a sequences
Falling input in the [Run] or [Hold] status ends the sequence and switches to Step 0.

Holding/resuming sequences
Falling input in the [Run] status pauses the sequence. Rising input during pause, or in the [Hold]
status, resumes the sequence from where it has been paused.

Event branch of the sequence
In the [Run] or [Hold] status and in the step where event branch is set to on, a falling input
generates an event branch. The sequence changes to the specified event branch destination step.

State branch of the sequence
In the [Run] or [Hold] status and in the step where state branch is set to on, a low level input
generates a state branch. The sequence changes to the specified state branch destination step. For
the timing to check the low level input,
☞
P.11-12.
It is not possible to control both the sequence start and the state branch via the multi-I/O connector
(
☞
P.11-11). When using the multi-I/O connector for the state branch, use the external trigger input
(BNC terminal) for the sequence start operation.
Check
• Start, stop, and event branch operations via the multi-I/O
connector causes a delay of approximately 0.2ms to 1.5ms and
fluctuations.
• Start operations by the external trigger input causes a delay of
approximately 15µs and fluctuations upon the waveform output,
and a delay of approximately 18µs and the fluctuations upon the
DC output. The start operation from the external trigger input is
faster than that from the multi-I/O connector.
