The Agilent 34904A module for the 34970A/34972A Data Acquisition/Switch Unit gives you the most flexible connection path between your device under test and your test equipment, allowing different instruments to be connected to multiple points on your DUT at the same time. Rows or columns may be connected between multiple modules to build 8 x 8, 4 x 16 or larger matrices, with up to 96 crosspoints in a single frame.

Modules specifications
The Agilent 34970A accuracy specifications already include the switching offset and reference junction errors shown in the chart. These errors are listed separately for determining system error with external measurement devices. These errors are listed separately for determining system error with external measurement devices.

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.
