Continuous sweep

When [Off] is selected
The output will be low level. This helps to reduce interference from synchronization output signal.
r) To assign a marker value for a center value, or to assign a center value for a marker
value
When the soft-key [Ctr
⇒ M kr] is presse
d on the second page, a center value is assigned for a marker
value. When the soft-key [Mkr
⇒ Ctr] is pressed, the
center value. If these soft-keys on the second page of the setting screen are not displayed, press the
right end soft-
key [▼1/2] to toggle the soft-key set.
s) To control the sweep start, stop and pause with an external logic signal
Set the external control [ExtCtrl] to enable [Enable] on page two of the setting screen to conduct
sweep operations with a TTL level logic input to the Multi I/O connector on the rear panel. This is
shared by CH1 and CH2.
It is recommended that this be set to disable [Disable] when not using an external control signal in
order to avoid malfunctions caused by exogenous noise. For pin number assignment,

The following operations can be performed.

Sweep start (pin 14)
Falling input to pin 14 starts the sweep. The sweep will restart from the beginning even if it is
already running.
In the case of a single sweep or a gated single sweep, the sweep will start from the beginning when
a trigger is received. The operation is a logical sum with the trigger source that is set.

Sweep stop (pin 13)
Falling input to pin 13 stops the sweep, and the output returns to the sweep start value.
However, in the case of a single sweep or a gated single sweep, the sweep will start from the
beginning when a new trigger is received.

Sweep hold/resume (pin 12)
Falling input to pin 12 holds the sweep if it is running. If the sweep is temporarily stopped, it will
restart from the hold position.
However, if a new trigger is received while a single sweep or gated single sweep is temporarily
