➢

You can use three different kinds of triggers in this program as mentioned in

this

chapter.

Start Trigger

and

Reference Trigger

can be set by

Trigger Mode

. For

Re-

Trigger

can be used by changing the numbers in

Retrigger Count

◼

Now the

Trigger Mode

is “

Reference

”

, and the PreTrigger Samples is 10.

Click

Start

to begin the data acquisition, the result is shown below:

Figure 23 Retrigger in Reference Trigger Mode

➢

Because the measured waveform is a straight line, the effect of reference trigger

can not be seen clearly.

◼

Now change the mode of trigger to

Retrigger

through giving

Retrigger Count

the

number 5 and click

Start

. A message will appear in the lower left corner:

“

Samples

acquired: 400/500

”.

Figure 24 Retrigger Complete State

➢

It shows the acquisition process through every trigger signal.
