DA795 DigiPro Digital Audio Analyzer


Overview

The DigiPro Digital Audio Analyzer analyzes any stereo PCM digital audio signal, and generates low-noise digital test signals, all at up to 24 bit/96k sample rate resolution. Digital audio analysis features and functionality normally found only on expensive bench test equipment, now available in a portable, easy-to-use and cost-effective package.

The DigiPro has All the connections you'll need - two sets of AES/EBU and SP/DIF inputs, including Toslink and ADAT, plus Word Clock in. Digital outputs, including AES/EBU, SP/DIF, and Toslink/ADAT, and Word Clock out. Analog stereo headphone and unbalanced mono analog outputs. ADAT sync and RS-232 serial for computer interfacing.

Features

The DA795 DigiPro Features:

check Transparency Test verifies that a device passes digital test waveforms without errors, using either synchronous or asynchronous test.
check Bitstream Analyzer totally analyzes digital stream characteristics to check actual word length and sample rate, bit activity, header information, flag errors, and low voltage.
check Lock Test tests whether two digital data or clock signals are locked (to <1ppm).
check Bitscope shows distortion, noise or jitter on an s/d or X-Y scope, and also applies the results to the internal speaker, headphones, and line output.
check Latency Test checks the signal delay through a device with a digital device input, and either digital or analog device output.
check Digital Watchdog captures signal errors for a test period and graphs the errors.
check Jitter Meter tests RMS interface jitter on a digital signal (to 150ps) or clock (to 35ps), as referenced to an internal crystal or external master clock.
check Clock/Sample Counter measures actual digital sample rate, word clock, and superclock frequencies.
check Distortion Meter measures THD+N (Total Harmonic Distortion & Noise) and more!
