Analog Input Ranges in APx500 Audio Analyzers – What you Should Know  
Using version 5.0.1 of APx500 software (released April 2, 2019), users can configure the analog generator to stay in a fixed output range. This is especially useful for testing acoustic devices, and  
Why Are Chirps Always Swept from Low to High?  
If you look at any APx measurement using a log-swept sine stimulus (a chirp), you might notice that the signal is always swept from low to high frequency. Learn more about why chirps are always swept  
Technote 116: Testing Smartphones and Tablets  
…Smartphones and tablets provide many ways to route audio. This technote shows you how to make connections and test the sound quality for a variety of these signal paths. Where possible, we will use file-based test…
