100 Things #7: Measure Device Characteristics Over Time with the Chart Recorder

Many of the virtual instruments available in SoundCheck have a strip chart recorder option that allow you to plot the instrument’s data over time. In this short video we take a quick look at how it is used with the multimeter, distortion analyzer and frequency counter. This functionality is directly equivalent to connecting a paper chart recorder to a classic, stand-alone hardware instrument.

Video Script: Measure Device Characteristics Over Time

Did you know that many of the virtual instruments available in SoundCheck have a strip chart recorder option that can allow you to plot the instrument’s data over time? Let’s take a look.

The Strip Chart Recorder was introduced in 2017 with the release of SoundCheck 16.  This module provides the multimeter, distortion analyzer and frequency counter the ability to plot measurements over time on a virtual strip chart.

This functionality is directly equivalent to connecting a paper chart recorder to a classic, stand-alone hardware instrument.

The Strip Chart Recorder can plot continuously or for a predefined amount of time with a scrolling or fixed y-axis. It can plot instantaneous results or repeating averages.

Results from the Strip Chart Recorder can be saved to the memory list and used inside a sequence just like any other virtual instrument.

This is an invaluable feature for environmental and reliability testing, as well as for any engineer that needs to characterize the behavior of a device over time.
