MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS 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 (MAX4559/MAX4560) IS MEASURED FROM ONE CHANNEL X_, Y_, Z_ TO ALL OTHER CHANNELS.

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