State Triggen A

pattern

is

specified

on any two

of the three inputs

with

the third input

used

as clock.

The

user

may

speci$

that a trigger

will

occur

on the

rising

or

falling

edge

of the input

specified as the

clock,

when

the

pattern

is

Setup

time

for

the

pattern

with

respect

to the clock

is 10 ns or less

and hold

Delayed Trigger Event-Delayed

The

trigger

can be

qualilied

by an

edge,

pattern,

time

qualihed pattern,

or state.

The

delay can

be specilied

as a number

of

occurrences of a

rising

or

falling edge

of any of the three inputs.

After

the

delay,

an occurrence

s;3

dsing

or faling

edge of

any of the three

inputs

will generate

the trigger.

The trigger

occurrence

value

is

selectable

from 1

to 16,CX[,000. The maximum edge

counting rate is

70 MHz

Time-Delayed

Mode: The trigger

can be

qualified

by an edge,

pattern,

or

state. The

delay

is

selectable

from

30

{1ftst

the

delay,

an

occurrence

of a

rising or

edge

of any of the three inputs

will

generate

the trigger.

The tri8ger

value

is selectable

from 1

to

16,000,000. The maximum edge counting
