Horizontal trigger position
Horizontal position is an adjustable feature that defines where the trigger occurs on the waveform record. It lets you choose how
much the instrument acquires before and after the trigger event. The part of the record that occurs before the trigger is the
pretrigger portion. The part that occurs after the trigger is the posttrigger portion. A longer posttrigger period may be useful when
you want to see the effects an event has on your system under test.
Pretrigger data can be valuable when troubleshooting. For example, if you are trying to find the cause of an unwanted glitch in
your test circuit, you can trigger on the glitch and make the pretrigger period large enough to capture data before the glitch. By
analyzing what happens before the glitch, you may uncover information that helps you find the source of the glitch.

Delayed trigger system
You can trigger with the A (Main) trigger system alone or you can combine the A (Main) trigger with the B (Delayed) trigger to
trigger on sequential events. When using sequential triggering, the A trigger event arms the trigger system, and the B trigger
event triggers the instrument when the B trigger conditions are met.
A and B triggers can (and typically do) have separate sources. The B trigger condition can be based on a time delay or a
specified number of counted events.

Advanced triggering
You can check the advanced trigger status in the readout. The readout indicates the trigger type and then shows sources, levels,
or any other parameters that are important for the particular trigger type.
