NOTES: MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS AT IC TERMINALS.
OFF-ISOLATION IS MEASURED BETWEEN X, Y AND "OFF" X_, Y_ TERMINAL ON EACH MUX.
ON-LOSS IS MEASURED BETWEEN X, Y AND "ON" X_, Y_ TERMINAL ON EACH MUX.
CROSSTALK IS MEASURED FROM ONE CHANNEL TO THE OTHER CHANNEL.
SIGNAL DIRECTION THROUGH MUX IS REVERSED; WORST VALUES ARE RECORDED.
