GUIDE FOR TESTING THE BASIC FUNCTIONALITY
OF THE INSTRUMENT.
This document provides instructions on how to test the basic functionality of your
Precision Power Analyzer in order to ensure it has a basic level of functionality;
this should be used as a pre cursor to any further fault investigations. Details are
provided of the instrument setup, the required connections between the PPA and
other basic test equipment commonly available in a laboratory. Furthermore,
screen shots of the expected results are displayed on the PPA.
Testing of the external inputs of the PPA is performed by monitoring the output
of a signal generator. To test the internal inputs of the PPA a breakout box with a
load connected is used, the PPA monitoring the AC mains supply with the current
shunts in series with the load and the voltage attenuators in parallel.
