Description

Digilyzer DL1 Digital Audio Analyzer

 

The Digilyzer DL1 is a powerful digital audio analyzer. Testing, monitoring and troubleshooting digital audio interfaces is straight-forward using this compact tool. The digital audio formats AES3, S/PDIF, TOSLINK and ADAT with sampling frequencies up to 96 kHz are supported.

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 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.
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.
