_________________________________Test Circuits/Timing Diagrams (continued)
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. SIGNAL
DIRECTION THROUGH SWITCH IS REVERSED; WORST
VALUES ARE RECORDED.
