Keysight Technologies Pulse Parameter Definitions Application Note Introduction Electrical pulses are used to synchronize, trigger or control multiple electrical devices in a test system. Pulses are also used for clock generation or radar testing. In order to describe a pulse and make its creation repeatable, a set of parameters has been defined. This document describes and illustrates all main pulse parameter definitions. It is a collection of terms used in the test and measurement environment. The information will help the reader to understand the nature of a pulse, and will make instrument specifications comparable amongst each other.

Overview of the pulse parameters Time Reference Point The time reference point is at the median of the amplitude (50% amplitude point on pulse edge). 100% 100% 50% Median 50% Median 0% 0% Figure 2. Time reference at median amplitude Pulse Period The time interval between the leading edge medians of consecutive output pulses. 50% 50% Pulse period Figure 3. Pulse period Pulse period
