The Agilent E1351A FET Multiplexer is a B-size 1-slot
register-based VXI module that switches 16 channels each
of high low and guard. The FET multiplexer module consists
of a B-size component card (labeled E1351-66201 on each one)
and a screw terminal block that plugs onto the component
card. The E1351A is functionally similar to the E1352A and
E1353A.
