704223 OPTICAL DISK INTER-SYMBOL INTERFERENCE ANALYSIS SOFTWARE
Analysis of inter-symbol interference using the code (pulse width) data is possible on the TA320/TA520, and on the TA720 you can perform the analysis using both pulse width and data-clock phase difference data. This software is an effective tool for evaluating today's ever faster and denser optical disk media characteristics, as well as recording strategies.
Multiple sets of measured data can be added.
Inter-Symbol Interference Analysis of Pulse Width Data and Data-Clock Phase Difference Data
You can specify points before and after a code as conditions which can be used to extract pulse width data and data-clock phase difference data (TA720 only). In the histogram analysis method, data that matches the specified conditions is extracted, and the histogram and a list of statisthics are displayed. In the matrix analysis method, the jitter and deviation analysis results between adjacent data points are displayed using a two-dimensional matrix table. For extraction conditions, you can specify an arbitrary code (nT), specify the code as a range, or specify only ODD or EVEN codes. You can also analyze only long codes having the same recording strategy characteristics.
Analyzes Maximum 2 M Samples of DataMultiple sets of measured data can be loaded from the TA720/TA520/TA320; allows analysis of up to 2 M samples.
Supports Any Modulation Method and SpeedYou can select a modulation method of 8-17 (EFM), 8-16 (EFM+), 1-7, or manual (arbitrarily set from 1T to 14T). You can also set the channel clock period for analysis of 8x speed for DVD or 48x speed for CD (when using the TA720).
Printing FunctionGraphs and data can be printed in black and white or color.
