PSpice User Guide Measurement expressions October 2019 790 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. For power users Creating custom measurement definitions Measurement definitions establish rules to locate interesting points and compute values for a waveform. In order to do this, a measurement definition needs: ■ A measurement definition name ■ A marked point expression These are the calculations that compute the final point on the waveform. ■ One or more search commands These commands specify how to search for the interesting points. Strategy 1. Decide what you want to measure. 2. Examine the waveforms you have and choose which points on the waveform are needed to calculate the measured value. 3. Compose the search commands to find and mark the desired points. 4. Use the marked points in the Marked Point Expressions to calculate the final value for the waveform. 5. Test the search commands and measurements. An easy way to create a new definition is to use the PSpice Trace menu. Select Measurements to open the Measurements dialog box and then do the following: 1. Select the definition most similar to your needs 2. Click Copy and follow the prompts to rename and edit.
