Keysight 34908A 40 Channel Single-Ended Multiplexer Module

• 40 Channel Single-Ended Multiplexer
• Single-wire switching for common-low applications
• 60 ch/s scanning
• Built-in thermocouple reference junction

Use the Keysight 34908A module for the 34970A or 34972A Data Acquisition/Switch Unit for the greatest density in common-low applications, such as battery test, component characterization, and benchtop testing. Each module switches 40 one-wire inputs. All two-wire internal measurements except current are supported. The module low connection is isolated from earth and can float up to 300 V.

346A/100 includes APC 3.5 (male) connector

• Frequency range: 10 MHz to 18 GHz
• Nominal ENR 6 dB
• VSWR: < 1.3:1
• Connectors: BNC (f) input bias / 3.5 mm (m)
• Low SWR for reducing noise figure measurement uncertainty
• Individually calibrated ENR values at specific frequencies

Keysight 346A noise source is the ideal companion to Keysight’s noise figure solutions. Since it is broadband (10 MHz to 18 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source reduces a major source of measurement uncertainty; reflections of test signals. The very small change in reflection coefficient (<0.01) from ON to OFF is designed especially for accurate characterization of input-impedance-sensitive devices (like GaAsFETs and many UHF amplifiers).
