Either. (either rising or falling edge)
(Edge, Delay, Rise & Fall trigger type
only)

Trigger Level
(Edge, Delay)

Level

Adjusts the trigger
manually using the
Trigger LEVEL knob.

LEVEL

Set to TTL
1.4V

Delay
(Delay)

Time

Sets the delay time (10ns ~ 10s)
between the trigger event and the real
trigger timing.
