AP - The Recognized Standard In Audio Test

2700 Series Audio AnalyzersHOME/PRODUCTS/2700 SERIES

High-Performance, 2-Channel
Audio Analyzers

The Classic Standard - combining simultaneous dual-domain functionality with very low distortion and noise performance.

AP 2722

Windows 8 support

AP2700 v3.30 SP2 now supports both Windows 7 and Windows 8 32- and 64-bit editions using the APIB-USB adaptor. See details in system requirements below.

The 2700 Series is designed for audio engineers who need high performance, low distortion and flexibility in their audio analyzer. With the Programmable Serial Interface Adapter (PSIA), it is a powerful solution for high-end converter and other chip designers.

The 2722’s true dual domain architecture enables extraordinary performance in measuring both analog and digital signals. The analog generator and analyzer performance surpasses that of any purely digital converter-based designs, while digital analysis techniques offer a wide array of precise, high-speed measurement techniques for either domain. Cross-domain work can be accomplished using the best of both worlds.

The typical THD+N of the 2700 Series is ≤ -115 dB at 2.0 Vrms. However, even with AP’s conservatively specified THD+N of -112 dB, the 2700 Series is second only to the APx555 in analog performance.

  • Dedicated analog circuitry for vanishingly low residual noise and THD+N
  • 192 kHz digital input and output capabilities
  • Generates and analyzes a broad palette of stimulus signals such as MLS, white and pink noise and other special purpose waveforms
  • Extensive API automation with AP Basic scripting and “learn mode”, LabVIEW driver and an IEEE.488 GPIB interface
  • User-defined sweeps, switcher support up to 192 channels

Model Options

2700 Series “A” (APIB) instruments have an APIB (Audio Precision Interface Bus) connector and require Windows XP, or later versions, to run the AP Control Software. “G” instruments include the IEEE-488.2 GPIB interface and can also be controlled directly through GPIB.

Dual domain. Two-channel analog input/output, analog analyzer and generator, DSP analyzer and generator, plus 192k digital input/output.

Analog domain only. Two-channel analog input/output, analog analyzer and generator, DSP analyzer and generator.

Analog domain only. Two-channel analog input/output,analog analyzer and generator.



What others are saying

“With its extremely low-distortion analog and digital signal generators, its extraordinarily low noise, high-resolution A/D converters, its ability to directly examine digital datastreams, its ability to perform extensive analysis in both analog and digital domains, and its intuitive software interface, the SYS-2722 is more than equal to the task of accurately assessing the behavior of 21st-century audio components.”
