General Information
Introduction
This manual contains information required to test, troubleshoot, and repair
the following Agilent relay multiplexers:
• E1343A 16-Channel High Voltage Relay Multiplexer
• E1344A 16-Channel High Voltage & Thermocouple Compensated
Relay Multiplexer
• E1345A 16-Channel Relay Multiplexer
• E1347A 16-Channel Thermocouple Compensated Relay Multiplexer
• E1355A 8-Channel 120-Ohm Relay Multiplexer
• E1356A 8-Channel 350-Ohm Relay Multiplexer.
Refer to the respective module’s User’s Manual for information on
programming and configuring these modules.
Figure 1-1 shows a typical layout for each of the relay multiplexers. Each
multiplexer consists of a component assembly and a terminal module. The
Agilent E1345A, E1347A, E1355A, and E1356A multiplexers use the same
component assembly, but each multiplexer uses a unique terminal module.
The Agilent E1343 and E1344 multiplexers use a different component
assembly.
