1 Answer

Answer :

A trigger is an external signal or input signal condition that initiates one or more instrument functions. Trigger settings include digital edges, software functions, and analog levels. This tutorial describes different trigger types that can be used with NI oscilloscopes.

You can use several kinds of triggering with NI high-speed digitizers, including immediate, software , hysteresis , edge, window, digital , and video triggering. Each kind of triggering uses a different NI-SCOPE Configure Trigger function


Edge Triggers

An edge trigger occurs when a signal crosses a trigger threshold that you specify. You can specify the slope as either positive (on the rising edge) or negative (on the falling edge) to the trigger. Edge triggering is possible on all analog trigger channels, such as 0, 1, or on the external trigger channel. The following figure shows edge triggering.

Window Triggers 

A window trigger occurs when a signal either enters or leaves a window you specify with the window mode parameters in the Configure Trigger Window function. Window triggering is possible on all analog trigger channels, such as 0, 1, or the external trigger input.

The following figure shows an entering window trigger.
