Digilyzer Digirator Exel Line for Digital Audio Signals Integrity Check When receiving incorrect Channel Status information the behavior of a device could be unpredictable. The In- tegrity Check compares measured pa- rameters with the indicated status and warns if any discrepancies are found. Scope The auto trigger and auto ranging scope gives a detailed view of the in- put audio signal in the time domain. DC offset problems and polarity issues are visible. Also ideal for understand- ing sampling peculiarities. Bit Statistics Measuring the audio resolution, finding stuck-bit failures and monitoring the activity of the user data bit are some im- portant applications of the bit statistics function. Basic channel status informa- tion 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. 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. Channel Status The complete channel status informa- tion is displayed in an easy-to-under- stand 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 measure- ment techniques including THD+N and high pass filters, allowing easy verifica- tion and debugging of dual domain devices like AD converters. VU + PPM The combined vu + PPM meter (vu = volume unit) with numerical maximum hold and over indicators helps identi- fying leveling problems and clipping. Reference grade performance with up to 40 screen updates per second. 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. Digital Audio Monitoring Channel Status Analysis Interface Carrier Measurements Dual Domain Functions 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. Analyzing & debugging digital audio interfaces and signals requires look- ing 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. Addi- tionally, the built in integrity check even alerts if protocol inconsistencies, which could cause serious troubles, are detected.

Beside a comprehensive set of audio test signals, the DR2 also supports surround sound test sequences for verification and adjustment of professional Dolby Digital, Dolby E and DTS installations. The internal low jitter clock generator can be synchronized to AES3, DARS, Word Clock and Video signals. Measurement of channel transparency, channel propagation delay and sample frequency is supported. dt 1 0. 00 0 06 .1 0 Digital Audio Signal Generator Sine Wave, Noise, Polarity A full range of digital audio test signals for maintenance, repair and calibra- tion of professional audio equipment is generated. User test signals may be stored as uncompressed WAV-files in the DR2 memory. Channel Status Monitoring Channel status information can be generated in professional and consum- er format and the most important pa- rameters may be manipulated manu- ally. Display of incoming channel status data is also supported. Channel Transparency Check The DR2 tests whether a transmission channel is transparent for non-linear PCM signals and indicates if Dolby E, Dolby Digital and/or DTS bit streams can pass. This test is also suitable for any digital audio recording device. Channel Delay Measurement The propagation delay between any DR2 digital audio output and the XLR sync input (which accepts AES3 signals) may be measured and displayed in sec- onds or video frames. Multi Format SYNC Input The DR2 accepts AES3, DARS, Word Clock and Video Black Burst (PAL and NTSC) synchronization signals. The input impedance of the sync input may be switched between 75 Ohm, 110 Ohm and High Z. Dolby Digital, Dolby E and DTS The DR2 wave file player can play back multi-channel bit stream files. A set of 5.1 test sequences for the verification and optimization of surround sound equipment and installations is stored on the unit’s flash disc.
