MEASUREMENTS ARE STANDARDIZED AGAINST SHORT AT SOCKET TERMINALS.

OFF-ISOLATION IS MEASURED BETWEEN COM AND "OFF" NO TERMINAL ON EACH SWITCH.

ON-LOSS IS MEASURED BETWEEN COM AND "ON" NO TERMINAL ON EACH SWITCH.

CROSSTALK (MAX4524) IS MEASURED FROM ONE CHANNEL (A, B) TO OTHER CHANNEL.

SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
