This Data Analyzer Module is a 3 slot VXI module.

A 43.26Gb/s signal will be demultiplexed in a cyclical way into 16x 2.7Gb/s signals (D/15).

The data processing (individual Ber analysis) is performed with the 16 2.7Gb/s channels.

The system software summarizes the measurements of each subrate channel and displays the result for the serial channel.

The output timing of the demux module data channels is automatically adjusted with the synchronization capability of the 2.7Gb/s analyzer channels.

This unit can operate in CDR (clock data recovery) mode or with an external clock.

In CDR mode the alignment for 50% criteria within the eye of the incoming signal is done automatically.

In external clock mode a delay adjustment between clock and data has to be performed externally.

In both clock modes there are three subrate clock outputs providing a 20/10GHz clock signal and a 2.5GHz clock signal.
