Digilyzer - Portable Digital Audio Analyzer with MiniLINK USB Interface


The Digilyzer DL1 is a powerful but easy to use digital audio analyzer. Testing, monitoring and troubleshooting digital audio interfaces is fast and straight forward using this compact tool. Virtually all digital audio formats including ADAT and sampling frequencies up to 96 kHz are supported.

With features like the DL1 unique integrity check, the integrated speaker, event & data logging, audio lens and many more digital audio becomes transparent and easy to debug.

Analyzing & debugging digital audio interfaces and signals requires looking at completely different parameters at the same time:

  • Interface carrier related parameters like level & sample frequency

  • Channel Status - related parameters like professional/consumer mode

  • Audio related parameters like audible content and level

The Digilyzer shows all these important parameter at one glance.

Additionally, the built in integrity check even alerts if protocol inconsistencies, which could cause serious troubles, are detected.

MiniLINK - the optional USB interface and PC Software for the Minilyzer ML1 and Digilyzer DL1 puts the Minstruments into a new league of affordable measurement tools. MiniLINK is pre-installed in all Acoustilyzer AL1.

MiniLINK allows documentation and data acquisition of all ML1/AL1/DL1 functions. In conjunction with the new firmware for Minilyzer (release 3.xx) and Digilyzer (release 2.xx) the instruments are able to store and transfer screen shots and measurement data for post processing.

MiniLINK is an upgradeable kit for all existing and new Minilyzers and Digilyzers. It consists of a small plug-in USB interface board that can be easily installed without any tools.

Channel Status
The complete channel status information is displayed in an easy-to-understand plain text format - according to the latest standards. Carrier frequency and level is available on nearly every screen.

Bit Statistics
Measuring the audio resolution, finding stuck-bit failures and monitoring the activity of the user data bit are some important applications of the bit statistics function. Basic channel status information is visible on the bottom line.

Event Logger
Intermittent faults are usually hard to find. The event logger tracks every change of the input signal (carrier, channel status or audio related) and allows long term checking and highlighting of possible problems.

Integrity Check
When receiving incorrect Channel Status information the behavior of a device could be unpredictable. The Integrity Check compares measured parameters with the indicated status and warns if any discrepancies are found.

Audio Monitoring
Beyond all the measurement power, the built in converter & speaker is one of the most important tools of the DL1. Featuring high quality headphone output, automatic gain control and monitoring of analog input signals.

The auto trigger and auto ranging scope gives a detailed view of the input audio signal in the time domain. DC offset problems and polarity issues are visible. Also ideal for understanding sampling peculiarities.

THD+N, Level, Frequency
Beside Level Peak measurements, the DL1 is equipped with RMS measurement techniques including THD+N and high pass filters, allowing easy verification and debugging of dual domain devices like AD converters.

Frequency Sweep
The DL1 automatically triggers to a sweep sequence with any step width and records the frequency response. Any stepped sweep may be used as signal source. After capture all sweep data is available.

The combined vu + PPM meter (vu = volume unit) with numerical maximum hold and over indicators helps identifying leveling problems and clipping. Reference grade performance with up to 40 screen updates per second.
