MEASUREMENTS ARE STANDARDIZED AGAINST SHORT AT SOCKET TERMINALS.
OFF ISOLATION IS MEASURED BETWEEN COM AND “OFF” TERMINAL ON EACH SWITCH.
ON LOSS IS MEASURED BETWEEN COM AND “ON” TERMINAL ON EACH SWITCH.
CROSSTALK IS MEASURED BETWEEN COMA AND COMB
TERMINALS ON EACH DEVICE.
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
