Product Overview

RENT AUDIO PRECISION APX555B Audio Analyzer (Call for Availability)

With a typical residual THD+N of -120 dB and over 1 MHz bandwidth, the Audio Precision APx555B surpasses the analog performance of all other audio analyzers, including a 5 dB improvement compared to our 2700 Series analyzer. Add to this FFTs of 1.2 million points and full 24-bit resolution, and you have performance unmatched by any other instrument. With the introduction of the B Series, the APx555 further lowers analog system residual distortion at sinewave frequencies above 50 kHz over the full 1 MHz bandwidth. 

The APx500 measurement software allows the B Series APx555 to adapt to the needs and preferences of audio designers, engineers and technicians. Sequence Mode provides complete, code-free automation of pre-defined measurement sequences to enable fast and reliable results. Bench Mode provides a real-time interface, with waveforms, FFTs and meters for virtually any parameter enabling the identification of important device interactions. The ADC Test Mode option provides an adjustable common mode VBias DC offset voltage on the balanced analog outputs. A Pin Voltage Protection mode, when enabled, prevents overvoltage damage to your direct-coupled ADC device’s input during performance tests.
