ATS-1 Series

Audio Analysers

Rack Mount and GPIB

The ATS-1 series of analyzers complements the Portable One series. Designed for rack mount and production applications, they offer the same measurement functionality as equivalent Portable One models, but include an IEEE-488 interface
as standard.

The ATS-1 series of analyzers complements the Portable One series. Designed for rack mount and production applications, they offer the same measurement functionality as equivalent Portable One models, but include an IEEE-488 interface as standard. 

They are housed in a fan-cooled metal case, designed for front or rear modular connector placement and rack mounting. The instruments include both the Audio Precision two-channel IEE-488.2 command set and a single channel HP8903B emulation mode. 

Automated testing is simplified with the industry-standard IEEE-488 interfaces on both models. ASCII commands are easy to use, and on-board intelligence simplifies sweeps and settled readings measurements.

ATS-1 Access is a comprehensive analog audio test set. Twelve different measurement functions are easily selected from the front panel.
Measures amplitude, signal-to-noise, distortion (THD+N) , SINAD, IMD (option), frequency, wow & flutter, input impedance plus AC mains check.
True 2-channel (stereo) modes measure two channel level, phase, amplitude ratio and crosstalk.

ATS-1 Dual Domain® is a comprehensive audio test set for both analog and digital audio, as well as for generation and measurement of AES/EBU/IEC digital characteristics such as jitter. Like our System One and System Two products, ATS-1 Dual Domain features true Dual Domain architecture.

Digital signals are generated and measured purely in the digital domain, resulting in the -140 dB distortion and -140 dB noise residuals necessary for making useful digital audio measurements.

True Dual Domain instrument, with independent analog and digital generators and analyzers.

Include all the functionality of the analog ATS-1 above.

Digital Audio – Generate signals and measure level & ratio, THD+N, frequency, phase, noise & crosstalk, IMD.

Digital interface – measure key interface parameters, including jitter, sample rate, AES signal voltage, frame delay, delay relative to house sync.

Major Options

IMD – Internal Intermodulation Distortion measurement and generation option; may also be retrofitted.
ATS-1 Dual Domain 96k Option – ATS-1 Dual Domain may be ordered with a 96kHz digital audio sampling rate option.
GPIB Interface – An IEEE Std 488.2 GPIB port is provided as a standard feature of the ATS-1 and ATS-1 Dual Domain versions to control all settings, and to acquire measurements and sweep data. Visual Basic sample code and utility programs for Windows 95/98/NT are provided on the CD-ROM. Analog features are supported with GPIB instrument software drivers for current versions of National Instruments LabWindows/CVI and LabView. The ATS-1 provides an additional HP8903B compatible command set that supports single channel measurement capabilities.
