NC2 and COM2 are open.

ill Measurements are standardized against shorts at IC terminals. Off-Isolation is

t measured between COM_

and “OFF” NO_ or NC_ terminal on each switch. On-Loss is measured between

G s 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;
