Audio Precision’s APx Active LoadBox Utility integrates APx with Audio Graph’s Active LoadBox for automated and comprehensive power amplifier load measurements.
Using your AP System with Active LoadBox
A great example of APx’s interactive capabilities being put to good use. Using the APx API and its ability to call third-party applications, Audio Precision has written a utility that allows APx to control the Active LoadBox dynamic load tester. The Active LoadBox is developed by AudioGraph and it’s a very useful instrument if you want a real-world view of your power amplifier designs.
The importance of making reactive load measurements
Measuring a power amplifier under both resistive and reactive load conditions is an essential part of the design process. Resistive load testing is commonly done by designers, and involves hooking a power amplifier up to non-inductive load resistors. It’s used to derive the power output ratings seen on specification sheets.
