This unit
The Keysight/Agilent/HP 44706A is a 60-channel single-ended relay multiplexer for high-density signal switching in automated test systems. It routes voltage, resistance, thermocouple, and strain gauge signals with low crosstalk and minimal offset error, integrating directly with HP 3852A data acquisition platforms. Each channel operates independently, accommodating field wiring up to 16 AWG and supporting switching rates up to 450 channels/second.

Key Features
Independent per-channel configuration
Low input impedance drift for precision measurement
Dual-module architecture: component module housing switching elements and 60-channel terminal module for field connections
Supports multiple signal types in single instrument
Typical Applications
Multi-channel voltage and resistance measurement
Thermocouple and strain gauge data acquisition
High-speed automated test environments requiring dense signal routing
Compatibility & Integration Designed for operation with the HP 3852A Data Acquisition system and compatible external voltmeters. Signals connect at the terminal module and route internally to the component module's switching matrix.
