The handheld DA795 Digital Audio Analyzer gives you a complete set of tests to troubleshoot and perform utility functions for digital audio analysis in a DSP-powered form.
With the ability to analyze any stereo digital audio signal, this device can generate low noise digital test signals up to 24 bit/96k sample rate resolutions. It features things normally found on bench test equipment, but is still in this small form factor that is compact and extremely easy to use.
Standard on the DA795 is plenty of connections for any scenario. It comes with two sets of AES/EBU and SP/DIF inputs, including Toslink and ADAT, as well as World Clock out. It has analog stereo headphones and unbalanced mono analog outputs in addition to ADAT sync and RS-232 serial for computer connectivity for PC interfacing.
The DigiPro Digital Audio Analyzer has a Transparency Test which will verify that a device passes waveforms without errors using a synchronous and asynchronous test. There is a bitstream analyzer which completely analyzes digital stream characteristics for actual word length and sample rate, bit activity, flag errors, header info, and low voltage.
The Lock Test checks if two digital data or clock signals are locked to <1ppm. Bitscope shows distortion, noise, and/or jitter on an s/d X-Y scope and will apply the result to the internal speaker, line-out, and headphones. Digital Watchdog captures signal errors for a test period which it converts to graphs. Distortion Meter will measure the THD+N and more. Clock/Sample Counter measures the digital sample rate, word clock, and superclock frequencies. Jitter Meter tests RMS interface jitter on a digital signal or clock.
