MEASUREMENTS ARE STANDARDIZED AGAINST SHORT AT SOCKET TERMINALS.

OFF ISOLATION IS MEASURED BETWEEN A, B AND "OFF" X, Y TERMINAL.

ON LOSS IS MEASURED BETWEEN A, B AND "ON" X, Y TERMINAL.

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

V- IS CONNECTED TO GND (0V) FOR SINGLE-SUPPLY OPERATION.
