Digital Audio Analyzer

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.

Digital Audio Monitoring
Channel Status Analysis
Interface Carrier Measurements

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

Up to 96 kHz, 24 Bit
AES3, S/PDIF, TOSLINK & ADAT

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.

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.

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

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.

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.

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.

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.

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.

Interface Carrier
Measurements:
Uncovers inaccurate
sample rates, bad carrier levels and faulty
data promptly!

The PPM gives an indication of what’s coming in
Measurement - in this
example the peak level
of channel A and B.

The “Quick Status” shows you the
most important vaules of the received channel status information.

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

USB Interface for Digilyzer DL1
The MiniLINK USB interface transforms the Digilyzer DL1 into
an affordable measurement instrument with PC connection.
MiniLINK is available as upgrade kit for all existing Digilyzers.
MiniLINK supports documentation and data acquisition of the entire
analyzer functionality in conjunction with the MiniLINK PC software.
Communication and power supply is enabled as soon as the supplied
Mini-USB cable is connected to the PC. Alternatively to store data and
bitmaps into the analyzers memory, MiniLINK supports online data
logging for most measurement functions. MAC compatibility cannot
be guaranteed.
