2700 Series

2700 Series High-Performance, Two-Channel Audio Analyzer

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

SYS-2722_hires
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.

• SYS-2722: Dual domain. Two-channel analog input/output, analog analyzer and generator, DSP analyzer and generator, plus 192k digital input/output.
• SYS-2712: Analog domain only. Two-channel analog input/output, analog analyzer and generator, DSP analyzer and generator.
• SYS-2702: Analog domain only. Two-channel analog input/output, analog analyzer and generator.

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.

The 2700 Series has five filter slots to accommodate analog filters in nearly any configuration. Standard configurations already include the S-AES17 or OPT-2020 filter. See below for other filters, or contact your local AP sales partner if you have more custom needs. For more information about filters, visit the Option Filter page.

2700 Series standard configurations also include tone burst, square wave and noise generation (formerly option S2-BUR).

Analog options

• OPT-2020: Pre-analyzer lowpass filter
• S2-IMD:     Adds IMD generator and analyzer to SYS-2702, SYS-2712, or SYS-2722
• S2-W&F:     Adds wow and flutter analyzer to SYS-2702, SYS-2712, or SYS-2722
• S2-BUR:     Adds tone burst, square wave and noise generator to SYS-2702, SYS-2712, or SYS-2722 (now included standard with all 2700 Series)
• S2-EURZ: Changes analog generator source impedance to be 40, 200, or 600 ohms in SYS-2702, SYS-2712, or SYS-2722
• OPT-2711: Adds the Dolby Digital Generator option to a new SYS-2722, allowing the encoding of stimulus tones in Dolby Digital (AC-3) before digital output. Includes IEC61937 and licensed Dolby Digital encoding software, and proprietary Audio Precision streaming interface (APSI) hardware installed in the instrument. (Not compatible with GPIB systems, not compatible with 64-bit versions of Windows. See AP Software Windows Version Compatibility for details.)
