MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS AT IC TERMINALS.
DIFFERENTIAL OFF-ISOLATION IS MEASURED BETWEEN COM_ AND “OFF” NO_ OR NC_ TERMINAL ON EACH SWITCH.
DIFFERENTIAL ON-LOSS IS MEASURED BETWEEN COM_ AND “ON” NO_ OR NC_ TERMINAL ON EACH SWITCH.
DIFFERENTIAL CROSSTALK IS MEASURED BETWEEN ANY TWO PAIRS.
