The Audio Precision ATS-1DD 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. The ATS-1 Dual Domain features true dual domain architecture. Digital signals are generated and measured purely in the digital domain, resulting in the extremely low distortion and noise residuals necessary for making useful digital audio measurements. ATS-1 Dual Domain provides complete and parallel measurement capabilities for both analog and digital audio signals. Measurements common to both domains include: Amplitude, Noise, Level (2 channels simultaneously), Frequency, Phase, THD+N, SMPTE/DIN, IMD, Crosstalk and Level Ratio. Standard A-weighting, CCIR 468, and LP/HP filters are included in both domains. RMS and quasi-peak (CCIR 468) detectors are available in both domains.
