APPENDIX B: FILE NAME CONVENTIONS FOR SAVED WAVEFORM

DATA

When live tests are made, the acquired waveforms are stored using these file names. If there is data

which has been already acquired, to perform tests using this package, the files must be renamed to

conform to these conventions: Please note (at this time) there is no distinction between bit rates, so

please use different folders for results at 12, 6, 3, and 1.5 Gbps.

These files have semi-rigid record length (time duration) requirements for performing the needed tests

(shown in table below)
