DVX-3

[DVX-3 PDF literature] 

DVX-3^™  is a compact stand-alone turnkey system with built-in touch-screen PC.  No monitor, keyboard, or mouse are required, although provisions for such are included.   It measures error rates and analog signals on DVDs and CDs of all formats.

New QuickScan™ feature will test a full DVD in as little as 38 seconds, or 80 min. CD in 48 seconds

Measures average and peak of PI, PI8, PIF. PO, PO8, POF, BLER, E11, E21, E31, E12, E22, E32

  Measures Reflectivity, I₁₁/Itop, I₃/Itop, Modulation (I₁₄/I_14H), Resolution (I₃/I_14H), Beta, Focus & Tracking error and Jitter

  Performs bit-for-bit verification on all formats including video, audio & Enhanced CD

  Creates & Verifies SHA-1 Disc Signature

  Easy to operate

  Built in Grading system

  Pass / Fail indicator with user defined limits

  Displays full disc information - Disc type, Data Format, TOC, MID, ISRC & UPC codes, Volume Descriptor, and Write Mode (DAO / TAO / SAO).

  Tests DVD-ROM, DVD±R, DVD±RW, DVD±R DL, CD-ROM, CD-DA, CD-R, CD-RW; All formats

DVX 
[DVX PDF literature] 

DVX^™ has all the features of DVX-3, but without the analog measurement capability and the built-in PC.  It consists of a specially modified drive and software that you can install in your own PC.  DVX will measure Beta and Jitter, and additional analog measurements can be added with the optional AMM-1 Analog Measurement Module.

CDX  
[CDX PDF literature]

A high-speed CD Analyzer that performs bit-for-bit data verification and format verification, plus measures error rates at up to 40X. It has an HF output so you can make pit geometry measurements using an oscilloscope. It is a PC based system which can include multiple drives.

   High speed - Tests a 650 MB disc in less than 3 minutes
   Can install two CDX in one PC for double throughput
   Bit-for-bit comparison to disc or image file
   Data format checking
 

QA-101
A compact, easy to use, and affordable means of measuring disc quality. It measures all error rates and provides the ability to make pit geometry measurements using an oscilloscope. The QA-101 can be used all by itself, or with a PC using the included QA-Net software. It can test all disc formats at 1X or 2X speed.
   No computer required
   Rack mountable or portable
   High-performance Holographic pickup

QA-201 
 The QA-201 jitter analyzer measures the average pit and land lengths (effect length), standard deviation (jitter) for each effect length, and the deviation of the average lengths from the ideal values. Information is displayed as bar graphs, histograms and a summary. The QA-201 uses a Philips CDM12 pickup that is the pickup used by Philips and specified in the Red/Yellow/Orange books for measuring jitter. This is the first affordable jitter measurement system to meet these standards. QA-201 also measures errors rates and provides HF oscilloscope outputs.

   1ns resolution
   Excellent correlation to Philips results

QA-301 

The Clover Systems QA-301 CD Analyzer is an easy to use and affordable tool for the evaluation of Compact Discs. It will test CD-DA, CD-ROM, CD-ROM XA, CD-I, CD-Recordable, and Photo-CD's. It was developed in collaboration with a major CD manufacturer, and is designed for factory floor operation by production personnel. It compares favorably with units costing many times more.  This PC-based system measures signals relating to pit geometry and error rates, which are then displayed or printed in graphic form showing performance over the whole disc. The system produces alarms to signal bad discs, or trends of degrading performance. Alarm limits (maximum & minimum) for each parameter can be set by the user. These settings are permanently saved, and password protected.

The QA-301 uses the Philips CDM4 single-beam pickup, as used by CD-CATS and Koch analyzers, thus providing good correlation with these other test systems. We can provide comparison data on request.  The QuickScan feature provides automatic sampling of the data at user-defined intervals, allowing complete characterization of a 60-minute disc in six minutes. Complete software calibration is included.  The system includes a rack-mount industrial Pentium computer, monitor, keyboard, & mouse.

Analog Measurement Option  
[AMM-1 PDF literature]

This option adds automatic measurement of analog parameters related to pit geometry.  Results are integrated into the reports and graphs.  Measures Reflectivity, I₁₁/I_top, Modulation (I₁₄/I_14H), I₃/I_top, Resolution (I₃/I₁₄₎, Beta, and Asymmetry.  Connects to DVX or CDX HF Out and PC's USB port.

The new PowerTower range of manual duplicators have been specifically designed to meet the growing demand for operators wishing to duplicate small to medium quantities of DVDs or CDs by the most cost effective method possible.

The PowerTower is very easy to use:  Just place the master in the reader and a blank disc in the recorder and it automatically starts to copy.  Alternatively, you can copy the master to the built-in hard drive and copy from the hard drive.  The 40 GB drive can store up to 8 DVD masters or 39 CD masters.

No PC is required. Can also verify the results against the master.  Copy from disc or disc image.

8X DVD Duplicators

Make 1, 3, or 7 copies simultaneously at up to 8X speed.  Copies a 4.5 GB disc in 15 minutes.

52X CD-R Duplicators

Make 1, 3, or 7 copies simultaneously at up to 52X speed.
