Rising Edge. Click to trigger on the rising edge of the waveform.

Falling Edge. Click to trigger on the falling edge of the waveform.

Trigger Level. Sets the trigger level. You can also set the trigger

level by dragging the trigger marker up or down on the screen.

Pre-trigger Time (0% to 100%). This parameter controls how

much of the waveform appears before the trigger point. It defaults

to 50%, which puts the trigger marker in the middle of the screen.

You can also control this parameter by dragging the trigger marker

to the left or right.

Post-trigger Delay Enable. Click this button to toggle the Post-

trigger Delay control (see next item).

Post-trigger Delay. The post-trigger delay is the time that

PicoScope waits after the trigger point before sampling. You can

also modify this parameter by dragging the trigger marker while

the Post-trigger Delay button is enabled. As you drag the

marker, you will see the post-trigger arrow displayed briefly. For

this control to have an effect, you must first make sure that the

Post-trigger Delay button is enabled.

See the reference topic "Trigger Timing" for information on how the

Pre-trigger Time and Post-trigger Delay controls interact.

Rapid Captures. In Rapid trigger mode, this is the number of

waveforms to capture in a sequence. They will be captured with the

minimum possible dead time between them.

This toolbar normally resides at the bottom of the program window, but can be moved

to the top using the Move Trigger toolbar to top control in Tools > Preferences >

Options.
