Runt trigger

A runt trigger occurs when the instrument detects a short pulse that crosses one threshold but fails to cross a second threshold

before recrossing the first.

■

You can set the instrument to detect any positive or negative runt pulse, or only those wider than a specified minimum width.

■

Runt pulses can also be qualified by the logical state of other channels.

Setup and hold trigger

A setup/hold trigger occurs when a data signal changes state inside of the user specified setup and hold times relative to the

clock. When you use setup/hold triggering, you define:

■

The channel containing the logic input (the data source) and the channel containing the clock (the clock source)

■

The direction of the clock edge to use

■

The clocking level and data level that the instrument uses to determine if a clock or data transition has occurred

■

The setup and hold times that together define a time range relative to the clock

Data that changes state within the setup/hold violation zone triggers the instrument. The next figure shows how the setup and

hold times that you choose position the violation zone relative to the clock.
