The Agilent 34906A RF multiplexer module for the 34970A/34972A Data Acquisition/Switch Unit offers broadband switching capabilities for high-frequency and pulsed signals. Use it to route test signals between your device under test and your signal generator, oscilloscope, spectrum analyzer, or other instrumentation. The RF multiplexers are arranged as two independent 1 x 4 multiplexers, each with a common shield and a switched center conductor. Connections can be made directly to SMB inputs with 2 GHz usable bandwidth, or to the BNC-to-SMB adapters provided with 1 bandwidth. Multiple banks may be cascaded together for applications requiring even larger topologies--create a stubless 16:1 multiplexer 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.
