Select Time Error Measurement from the Tools > Calnex Analysis Tool (1588v2) menu.
This will start CAT, which allows the observation and analysis of data captured by the Paragon-X
hardware and application.

When CAT launches, the Select file page is initially displayed and the live capture file pre-selected.
The Select Metrics button presents a list of available clock, packet and time error metrics, with
those appropriate for the current test pre-enabled. for further information on any given metric,

The View Results button will display graphs and statistics for the currently-loaded data. Each type

*Please note that it is expected that idle symbols are transmitted in pairs. If testing using 100M interfaces,
please confirm with the PHY vendor that their implementation uses this technique. At 100M rate, the presence
of odd idle symbols will result in timing measurements being offset by one clock cycle (40ns).
