Auto audio analyzers provide four channels

Suited for testing automotive audio systems, which typically have two analog inputs and four outputs, the 521 and 526 APx series audio analyzers provide two output and four input channels for efficient testing of typical systems with one analyzer. The 526 also has 192K digital I/O.

Both models have a typical THD+N of -108 dB (at 1 kHz, 2.5 V). and can take up to 14 measurements in 7 s. Users can run tests with one click or define sequences of measurements with multiple signal paths, pass/fail limits, and automatically generated reports. Real-time signal monitors include residual THD+N in scope view and a 1-Mpoint FFT. (From $14,000 — available now.)
