Overview

This example demonstrates how to measure the period and frequency in response to different aperture and settling time configurations.

 

Description

Even though there are benchmarked values for certain digits of resolution in the DMM specs, it is possible to set your own aperture time and settling time in order to achieve a particular reading rate. Using the niDMM Get Measurement Period.vi, we can determine the measurement period based on a certain aperture time and settling time that we set with the niDMM Property Node. By taking the inverse of the period, the reading rate can be determined.
