History of "BER-PLOT"

In 2004, the graph tool for bit-error-rate performance was sold in only Japan as the name of "Shanghai-crab". At that time, many people made a chart of BER performances on error-rate grid sheet by hand. This application is supplied with many major companies, government research institutes, national universities, etc. The people in the United State requested to create this application for oversea use.

What is import file formats ?

Supported file formats are Comma-Separated Values (*.csv) and Microsoft™ Excel Worksheet (*.xls). However reading speed of Excel files is relatively slow in comparison to that of CSV files. I recommend you use CSV format in terms of reading speed and stability.

How does BER performance draw ?

A BER performance is calculated based on these formula for an intensity modulated direct detection (IM-DD) receiver.
