Transition

In programming

the

PC40,

the

transition values refer

the

end-point

(continued) each delay and

each

duration. Each

end

-point is defined in relation to

the

trigger signal, which is

the

starting point

the entire transition

sequence. Each transition value is a distance measure that

converted

time values.

NOTE:

The

initial

delay

for an application with a leading edge trigger

has to account for the trigger

gun distance (A in Figure 4.3) plus

the

distance from

the

leading edge to the first transition

(Bin

Figure 4.3).

The first transition

(f1) in Figure 4.3 is

700

The

700

ms length

includes the trigger to

gun

interval of 400

plus

the

300

from

the

leading edge

the

substrate

the

first delay interval.

The second transition

(f2) is

1000

ms, which

the

end point

the first

duration

relation

the

trigger

signal. It is important not to confuse

the

length

the duration, 300 ms, with

the

transition, T2,

ich

1000 ms.
