Configuration
The switch consists of eight banks of eight Hi and Lo
switches, each bank having its own eight Hi and Lo common.
There are seven programmable control switches and six sets
of wire jumpers. These wire jumpers allow all bank commons
to produce either eight 1x8 two-wire multiplexers, four 1x8
two-wire multiplexers, and two 1x16 two-wire multiplexers, or
four 1x16 two-wire multiplexers. Other switching topologies
are also possible.
One 2.5-in analog bus cable (E1400-61605) is included to
connect the analog buses of multiple slot-adjacent E1460A
modules or a slot-adjacent E1411B multimeter module. The
analog bus cable, easily installed at the faceplate of the
component card, lets you connect the E1460A with the E1411B
DMM. Using SCPI commands sent to the E1411B, you can
close channels configured as two-wire, three-wire, or
four- wire in the E1460A. It is possible (but less convenient) to
connect the analog bus by attaching your own wiring to the
E1460A and E1411B screw terminals.
The E1460A User Manual contains configuration and
programming examples for one-wire through four-wire
switching modes, cable test, switchbox, scanning, triggering,
and scanning with an external multimeter.
