Triggers

Accurate measurement of signals requires that the start points used to acquire data be consistent. These start points are called “triggers.”

“Voltage measurement”—everything from its basic knowledge to advanced techniques is published in this guide!

This guide introduces readily available techniques, ranging from basic measurement methods to sampling cycle selection and trigger setting.

Setting triggers

In actual measurement, it is important to set triggers to collect target waveforms.

In general, the following two types of triggers are used for measurement.

Rising trigger: Measurement is triggered when the voltage changes in the positive direction and exceeds the specified voltage.
Falling trigger: Measurement is triggered when the voltage changes in the negative direction and falls below the specified voltage.

When using triggers, set the number of sampling points so that the target waveforms are included. To check the conditions before and after the target phenomenon, set pre-triggers.
