Configuring the Pre-trigger settings

Pre-trigger

You can record not only

waveforms that appear after a

start trigger has been activated,

but also those that appear before

the trigger is activated.

Also records data before the start trigger.

Start

Specified pre-

trigger length

Recording length or

recording time

The pre-trigger is set in percent (%) of the recording length.

Setting all the trigger sources (analog, interval triggers, etc.) to

[Off]

disables pre-trigger setting.
