Audio Precision SYS-2720A

Audio Precision SYS-2720A (Digital domain only) DSP analyzer and generator with 192k digital input/output.

The 2700 Series is designed for audio engineers who need the highest performance, lowest distortion and greatest flexibility possible in their audio analyzer.

The 2722's true dual domain architecture enables uncompromised measurement of both analog and digital signals: the analog generator and analyzer performance surpasses that of any digital converter-based design, 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 the industry's undisputed performance leader.

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

When ordering a SYS-2702, 2712 or 2722 (“A” or “G”), you MUST specify (as a separate line item) one of the following low pass filter selections (included in price of instrument)

- S-AES17 Special lowpass filter satisfies AES17 for measurements in the presence of out-of-band noise. Includes 20 kHz and 40 kHz brick wall filters (FLP-B20K and FLP-B40K). This filter requires two filter slots.

- OPT-2020 Pre-analyzer lowpass filter

Available Options:
IMD = Adds IMD generator and analyzer to SYS-2702, SYS-2712, or SYS-2722
W&F = Adds wow and flutter analyzer to SYS-2702, SYS-2712, or SYS-2722
BUR = Adds tone burst, square wave and noise generator to SYS-2702, SYS-2712,
or SYS-2722
EURZ = Changes analog generator source impedance to be 40, 200, or 600 ohms in SYS-2702, SYS-2712, or SYS-2722
2711 = Adds the Dolby Digital Generator option to a new SYS-2722 or SYS-2720, 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)
