Audio Precision 2700 Series

Further product information.

The Dual Domain capabilities of 2700 Series provide uncompromised performance in both analog and digital domains. The state-of-the-art analog hardware in 2700 Series reaches an unmatched -112 dB specification for THD+N audio testing outperforming today's best converters.

2700 Series provides a higher performance level with an extremely low residual distortion that testing cutting edge converters requires. The Programmable Serial Interface Adapter option eliminates the need to build your own interface to test those audio products with non-standard or proprietary interfaces. Time previously spent building an interface can be spent getting your product to market faster.

2700 Series includes many of the proven, reliable features found in preceding systems, including:

• Harmonic Distortion Analyzer
• Multitone Analyzer
• Serial Digital Interface Analyzer
• PC-based functionality.

The Harmonic Distortion Analyzer provides insight into a variety of circuit malfunctions, allowing an engineer or technician to isolate circuit problems and fix them quickly. The Multitone Analyzer-an FFT analyzer coupled with an arbitrary waveform generator-performs a variety of performance tests quickly.

The Serial Digital Interface Analyzer has a 30 MHz analyzer as well as an error generator that measures and displays the digital interface signal, and tests a circuit's ability to perform in the presence of jitter and other impairments.

With PC-based functionality, 2700 Series lets you leverage your existing PC investment and gives you a familiar interface to

• Monitor instruments
• Graphically display test data
• Manage files for test setups
• Easily share and archive data
• Generate reports with your preferred word processing application
• Export test data to analysis programs---such as MATLAB ---for extended analysis;
• Deploy with its 'learn mode' feature to create and run test sequences --without extensive programming experience

All of the configurations and results viewing are performed through Audio Precision Control Software installed on a PC. The communication is carried out via either the proprietary APIB interface or USB. When using APIB, following PC interface cards are offered:

• PCI bus APIB PC Interface card
• PCMCIA APIB PC Interface card
• APIB Interface card supporting PCI Express bus slot
