  • Not Applicable for this App


Some of the Measurement Apps included in this bundle combine multiple parameters together, and have separate Apps that measure each of those parameters individually as well. The primary purpose of a combined Measurement App is for use in a Compliance App, where it allows the test to proceed as quickly as possible by minimizing the recalculation that would be required for measuring similar parameters in different Apps. The individual Measurement Apps, on the other hand, are primarily intended for use in a Debug scenario, where having all of the statistics and data for a particular parameter is required.
