MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS AT IC TERMINALS.

OFF-ISOLATION IS MEASURED BETWEEN COM_ AND "OFF" NO_ OR NC TERMINAL ON EACH SWITCH.

-3dB BANDWIDTH IS MEASURED BETWEEN COM_ AND "ON" NO_ OR NC TERMINAL ON EACH SWITCH.

CROSSTALK IS MEASURED FROM ONE CHANNEL TO THE OTHER CHANNEL.

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