To use.

1. Set up the A Event and B Events from their individual tabs.

2. Select the A–>B Seq tab; then click Trig on nth Event.

3. Set the Horizontal Delay Mode button to On. Select the number of B events with the Trig Event control, use the Acquisition

Delay control to delay the acquisition relative to the B event, and adjust the Ref Point and B Trig Level controls as

necessary.

4. Set the B Event Scan button to On. Click Setup button to set the values for B Event Advance mode, Start Event, End Event,

and Advance After.

Behavior. Use this sequence to trigger the instrument on the nth occurrence of the B event after the A event. The instrument

then delays the acquisition for the amount of time specified by the Acquisition Delay control. After the delay time has expired, the

instrument displays the data.

When you enable the B-Event Scan, the instrument automatically advances the B-Event value to capture a different portion of the

signal. The B-Event value is initialized to the Start Event value and is advanced to the End Event value by one of three Advance

Methods namely Sequential, Random, and Toggle.
