Multiplexer Selection Guide

Choose between the broad functionality of the 34901A, the high speed scanning of the 34902A, or the single-ended density of the 34908A. These three modules are the only way to connect to the 34970A internal DMM. They can be used to scan with external instruments as well. All multiplexer modules employ break-beforemake scanning, ensuring only one closed channel (or channel pair) at a time. Multiple channel closures are allowed on the 34901A and 34902A modules when not configured for scanning. The 34908A does not allow multiple channel closures at any time.

Up to three modules, in any combination, can be inserted into a single mainframe. The 34970A?s internal DMM connections are accessible only through the 34901A, 34902A, and 34908A low frequency multiplexers. On-module screw terminals accept wire sizes from 16 gage to 22 gage. Twenty-gage wire is recommended for high channel count applications. The 34905A and 34906A RF Multiplexers use SMB connectors. A standard set of (10) BNC-to-SMB adapter cables is provided with each RF module for convenient BNC connections.
