AP 2700 Series Audio Analyzers

PRODUCT DESCRIPTION

2700 Series High-Performance, Two-Channel Audio Analyzer
The Classic Standard - simultaneous dual-domain functionality with very low distortion and noise performance

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 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.

Analog Performance
Combining dual-domain functionality with very low distortion and noise performance, the 2700 Series is the classic standard for audio analysis, perfect for audio engineers who need high performance, low distortion and high reliability.
Flexible Control
AP2700.exe is the control software for 2700 Series instruments. Running on the controlling PC, AP2700 is a powerful and sophisticated real-time interface, with hardware and software system modules and functions controlled using settings on virtual panels, and measurement results displayed in virtual meter and graph readings.
Measurement Speed
The 2700 Series offers an array of powerful, time-saving analysis tools to speed your testing procedures including, but not limited to: multitoned testing, harmonic distortion analysis, filter creation and more.
Digital Analysis
The 2700 Series offers both AES3 and IEC60958 serial digital interfaces, with fully configurable serial data and clock ports available via the auxiliary PSIA-2722 Programmable Serial Interface Adapter.

SYSTEM REQUIREMENTS
• IBM-compatible PC with the minimum processor type and memory required by Microsoft for the installed operating system.
• Supports Microsoft Windows XP Professional SP2 and SP3 (32-bit), Windows Vista Business and Ultimate Editions (32-bit), Windows 7 Professional and Ultimate Editions SP1 (32- and 64-bit), Windows 8 Pro and Enterprise Editions (32- and 64-bit).
• The AP2700 64-bit driver only supports AP’s APIB-USB adapter, and is not compatible with APIB add-in cards (ISA, PCI, PCIe, and PCMCIA buses).
• The AP2700 64-bit driver does not support the OPT-2711 Dolby Digital generator option. Instruments with OPT-2711 installed will function correctly on a 64-bit PC, but the Dolby Digital generator will not be available.
