Measurements are standardized against
short at socket terminals. OFF isolation is
measured between COM and OFF terminals
on each switch. Bandwidth is measured between
COM and ON terminals on each switch. Signal
direction through switch is reversed; worst
values are recorded.
OFF isolation = 20 log V_O/V_I
