Measurements are standardized against
OFF isolation = 20 log V_O/V_I
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 ⁽¹⁾_{Add 50-W termination for}
direction through switch is reversed; worst
OFF isolation
values are recorded.
