CD Analyzers

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.

Duplication Systems

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.
