Introducing the low cost solution to CD testing.The importance of maintaining high quality standards in all phases of CD production cannot be overstated. Replicators, distributors, CD-ROM publishers, and CD-R users all need to verify the quality of their product to maximize customer satisfaction and avoid problems. Until now, such testing equipment cost tens of thousands of dollars and was out of reach of many potential applications. The QA-101 now provides an easy-to-use, accurate, and repeatable means of measuring disc quality. APPLICATIONSDESCRIPTIONThe QA-101 is an industrial-grade player that measures and displays error rates, dropouts, and tracking loss. It will analyze CD-DA, CD-ROM, Mixed Mode, CD-ROM/XA, CD-I, CD-R, and Photo-CD discs at both 1X and 2X speeds. It has BNC jacks on the back with buffered HF and TRK outputs that allow you to measure pit geometry related signals such as I11, I3, and asymmetry using an oscilloscope. Each occurrence of E22, E32, Dropout, and Track Loss is printed with its location in real time using the built-in printer port. A summary of disc performance including all error statistics and Grade is printed at the conclusion of the test. This allows completely automatic operation without a computer. The built-in grading system gives you an easy to use, instant evaluation of the overall disc quality based on the measured values. Five different categories provide a wide range of performance evaluation. The serial interface allows you to store and graph the data on a PC. A computer is not required however, for basic operation. FEATURES
MEASUREMENTSError rates are the single most useful measurement of disc quality, since all serious disc problems will cause increased error rates. Errors measured are: BLER (Block Error Rate), E11, E21, E31, E12, E22, and E32 (uncorrectable errors). Current, average, and peak values for all errors can be displayed on the built-in Vacuum Florescent display. Total E22, E32 (uncorrectable) errors and dropouts are also displayed. A red LED warns at a glance if an uncorrectable error has occurred. This is especially important for CD-ROM and pre-mastering applications. A track loss indicator warns of excessive tracking error. Buffered HF and TRK signal output jacks on the rear panel provide a simple means of measuring pit geometry using an oscilloscope. You can measure I11, I3, Asymmetry, eccentricity, crosstalk, and reflectivity. The dropout counter also helps decide if errors are caused by local defects, or poor pit geometry. The operator's manual fully explains how to interpret the data, and make measurements related to pit geometry. A thorough analysis of disc performance is possible. The QA-101D provides both analog and digital audio (AES / EBU) outputs.. QA-NetThe optional QA-Net Software is a Windows program that gathers data from up to eight QA-101s in real time. A serial interface allows up to 8 QA-101s to be connected to a computer on one twisted pair using one COM port. Data is uploaded to the PC where it can be displayed graphically, printed, and stored.
