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. 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 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 even alerts if protocol inconsistencies are detected, which could cause serious troubles. The Digilyzer shows all these important parameter at one glance:
Simple selection of functions, input format and input channel using pull down menus.
Carrier information uncovers inaccurate rates, bad carrier levels and faulty data promptly.
The PPM gives and indication of what's coming in.
Measurement of levels
The "Quick Status shows you the most important values of the received channel status information.
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.
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.
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.
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.
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.
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.
