S-PARAMETERS TEST METHOD PROCEDURE

In order to calculate the cable parameters as defined in SFF-8431 table 37, following test procedure is required:
•Measure S-parameters for MCB-HCB from point B” to B, see 3.1.1
•Measure the s4p for through S-parameters for cable end 1 to cable end 2, see 3.1.2
•Measure the s4p for crosstalk S-parameters for cable end under test, see 3.1.3
S-Parameter Test Method Matlab code, Appendix A, reads the three S-parameters s4p files in order to calculate the cable parameters dWDP, VMA loss, and VCR.
