DA795 Datasheet
The Sencore DA795 DigiPro Digital Audio Analyzer provides a powerful, complete set of test, troubleshooting and utility functions for digital audio analysis, in a hand-held DSP-powered device. With the DA795 Digital Audio Analyzer, you can analyze any stereo digital audio signal, and generate 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, are now available in a portable, easy-to-use and cost-effective package.
Sencore DA795 Features
  • Bitstream Analyzer totally analyzes a digital stream to check actual word length and sample rate, bit activity, header status information, flag errors, byte detail, and low carrier voltage.
  • Bitscope shows distortion, noise, jitter, or phase on an S/D or X-Y scope, and also applies the results to the internal speaker, headphones, and line output.
  • Pass Mode modifies a signal’s status information, performs sample-rate conversion, changes signal formats (AES/SPDIF/ADAT), or adds digital signal gain or attenuation.
  • Clock/Sample Counter measures sample rate/word clock (±0.01Hz) and superclock (±4Hz).
  • 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.
  • LAeq Dialog Level measures "equivalent" average sound level. Helps broadcasters meet FCC Dialog Level (dialnorm) spec.
  • Digital Watchdog captures signal errors for a test period and graphs the errors.
  • Latency Test checks the signal delay through a device with a digital audio input.
  • Cable Tester tests digital audio cables for functional quality with Julian Dunn J-test waveform.
  • Transparency Test verifies that a signal path or recording/storage device passes digital test waveforms without errors, with either synchronous or asynchronous test.
