ATS-1: Audio Precision Quality in a Stand-Alone Package
The ATS-1 family of audio test instruments—at home on the
bench, or in a test rack under GPIB control.
With thousands of units sold, you’ll find the ATS-1 family of audio analyzers in operation
around the world in maintenance, engineering and production facilities. Whether in broad-
cast, communications, bench or production use, ATS-1 offers a complete easy-to-use audio
test set ready for almost any environment. With twelve different measurement functions
selectable at the push of a button, ATS-1 is comprehensive while remaining user-friendly. Its
popularity is no less due to its outstanding performance specifications; yet ATS-1 is as af-
fordable as lower-performing test sets.
The ATS-1
ATS-1 Access includes comprehensive analog generation and measurement, with two outputs
and two inputs. Easy-to-set-up sweep capability produces graphs of frequency response, dis-
tortion vs. frequency and even amplitude sweeps. Non-volatile storage of up to 30 tests
allows easy one-button recall of your favorite test setup. Connect ATS-1 to a compatible
printer and produce reports incorporating high-resolution graphs. If you work with digital
audio, the ATS-1 Dual Domain® model adds AES3/SPDIF audio and interface measurement ca-
pabilities to the comprehensive analog capabilities of the ATS-1 family.
Analog+Digital+AES3/SPDIF: the ATS-1 Dual Domain
ATS-1 Dual Domain® is a comprehensive audio test set for both analog and digital audio, as
well as for generation and measurement of AES3/SPDIF digital interface characteristics such
as jitter. Like our 2700 Series family of instruments, ATS-1 Dual Domain features true dual
domain architecture. Digital signals are generated and measured purely in the digital do-
main, resulting in the extremely low distortion and noise residuals necessary for making
useful digital audio measurements.
