Overview

The Digilyzer analyzes 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 alerts if protocol inconsistencies, which could cause serious troubles, are detected. Digital audio becomes transparent and easy to debug with the integrated speaker, event logging and the audio lens. The Digilyzer shows all these important parameters at one glance.


Features

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 all main screens.

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.

Scope

The auto trigger and auto ranging scope gives a detailed view of the input audio signal in the time domain. The scope visualizes DC offset problems, polarity issues and is 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.

vu/PPM
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.
