N2262A 4 X 8 2-Wire Matrix Switch Module - Agilent Technologies Agilent 3499A User Manual

N2262A 4 x 8 2-Wire Matrix Switch Module

The Agilent N2262A 4 x 8 Matrix module contains 32 2-wire nodes
(crosspoints) organized in a 4-row by 8-column configuration. Each node
in the matrix contains a 2-wire latching relay for switching both Hi (H)
and Lo (L) terminals of a signal line. Multiple switches can be closed,
allowing any combination of row-to-column connections.
The parallel switching feature makes it well suited for high speed
switching applications. Up to 8 2-wire node/crosspoint relays in the same
row can be closed all at once (parallel switching).
The N2262A provides a convenient way to connect multiple test
instruments to multiple test points on a device or to multiple devices.
Multiple N2262A modules can be connected together, or used in
conjunction with other modules such as the N2260A 40-Channel MUX to
provide a wide variety of switching combinations.
Specifications for the Agilent N2262A are given on page 307.
N2262A Simplified Schematic
A simplified schematic is shown below. The N2262A contains
32 2-wire crosspoints organized in a 4-row by 8-column configuration.
Each crosspoint relay has a unique two digit channel number mn,
where m = row number (0-3) and n = column number (0-7).
