Measurements are standardized against short at socket terminals.
Off isolation is measured between COM_ and OFF NO_ terminal on each switch.
On loss is measured between COM_ and ON terminal on each switch.
Crosstalk (PS4531/PS4532) is measured from one channel (A,B,C) to all other channels.
Signal direction through switch is reversed; worst values are recorded.
