DL1 Digital Audio Analyser

DL1 Technical Specifications    

The Digilyzer DL1 is a powerful but easy-to-use digital audio analyser. 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. Digital audio becomes transparent and easy to debug with features like the unique integrity check, the integrated speaker, event logging and the audio lens.

The Digilyzer analyses and debugs different parameters within digital audio signals at the same time:

  • Interface carrier parameters like level & sample frequency
  • Channel Status parameters like professional/consumer mode
  • Audio related parameters like audible content and level

The built in integrity check even alerts if protocol inconsistencies are detected, which could cause serious troubles. The Digilyzer shows all these important parameter at one glance.

Digilyzer Features

  • Channel Status

The complete channel status information is displayed in an easy-to-understand plain text format - in accordance with 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 also visible.

  • 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 behaviour of a device can be unpredictable. The Integrity Check compares measured parameters with the indicated status and warns if any discrepancies are found.

  • Audio Monitoring

In addition to all the measurement functionality, 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 analogue input signals.

  • Scope

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

In addition to 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.

  • vu/PPM

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