Description
The Agilent E1345A General-Purpose Reed Relay Multiplexer
is a B-size, 1-slot, register-based VXI module that
switches 16 channels of high, low, and guard each. The
multiplexer has low thermal offset performance. This module
consists of a B-size component card (labeled E1345-66201)
and a screw terminal block that plugs onto the component
card. The E1345A is functionally similar to the E1347A.
Configuration
One analog bus cable is shipped with each module, making it
easy to connect common outputs together for slot-adjacent
modules. If you are using a B-size mainframe, Agilent E1300B
or E1301B, use the analog bus cable shipped with the E1326B
DMM to connect it to the multiplexer(s).
The E1345A multiplexer is arranged into two banks of eight
switches, each having its own common high, low, and guard
screw terminals accessible on the terminal block. Tree-
switched common high, low, and guard screw terminals and
analog bus connections provide access to all 16 channels. The
module may be programmed as either a single 1x16 three-wire
multiplexer, two independent 1x8 three-wire multiplexers (for
four-wire Ω), or a 1x8 six-wire multiplexer.
C-size Adapter
For installing the E1345A in a C-size mainframe, the E1403C
active adapter is recommended.
