Converter Based

The ATS-2 offers an excellent value in audio analyzers. Its converter-based architecture keeps the cost down while offering a wide range of features at high levels of performance. Converter-based audio analyzers generate and analyze signals in the digital domain and use analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) for analog input and output.

Low Distortion

• Analog THD+N (system measurement), less than –101 dB + 1.6 µV, 20 Hz to 20 kHz.
• Digital THD+N (system measurement), less than –160 dB.

Wide Bandwidth

• Analog signals generated 2 Hz to 61 kHz.
• Digital signals generated 2 Hz to 50% of sample rate (in single-connector mode, 2 Hz to 54 kHz; to 108 kHz in dual-connector mode).
• Analog measurements from 10 Hz to 120 kHz (with Performance Option).
• Digital measurements to 47% of sample rate (in single-connector mode, from 10 Hz to 50.7 kHz; to 108 kHz in dual-connector mode).

Low Noise

• Analog analyzer noise less than 1.2 µV rms, A-weighted.

Flat Response

• Typically ±0.01 dB, 20 Hz to 20 kHz.

Crosstalk

• Less than  –100 dB +3 µV at 20 kHz, analog input. 
• Less than  –100 dB +3 µV 20 Hz to 20 kHz, analog output 

Residual Jitter

• Less than  2 ns in a 700 Hz to 100 kHz measurement bandwidth.

FFT Acquisitions

• Up to 256 k samples.
