Setting the APx Generator Level for Arbitrary Waveforms  
In this post, we describe the relationship between the Generator Level setting and the measured level for arbitrary waveforms, as well as a procedure to help choose an appropriate Generator Level  
FFT Spectrum and Spectral Densities – Same Data, Different Scaling  
Fast Fourier Transform (FFT) analysis, which converts signals from the time domain to their frequency domain equivalent, is incredibly useful in audio test.  
New Feature in APx500 v5.0.1: Fixed Analog Output Range  
Using APx500 software version 5.0.1, users can configure the analog generator to stay in a fixed output range. This is useful for testing acoustic devices and electronic devices with sensitive input  
2700 Series Analog Performance  
… of the 2700 Series. THD+N Our conservatively spec’d system residual THD+N is less than –112 dB, as shown in the graph below. This represents an advantage of about 9 dB over converter-based analyzer systems.…  
Hearing Aids are Truly Unique—from an Audio Test Perspective  
Hearing aids are truly unique from an audio test perspective being one of the few audio devices that has both acoustic input and output.
