Keysight / Agilent / HP 44470A 10-Channel Multiplexer Module

The Keysight/Agilent/HP 44470A is a 10-channel single-ended multiplexer module designed for integration into data acquisition and automated test systems. It routes multiple input signals sequentially to a single measurement instrument, extending test point monitoring capacity without requiring parallel measurement channels. The module connects directly to compatible mainframe systems and operates under remote control via standard instrument interfaces, making it ideal for applications requiring efficient signal switching and continuous system monitoring across distributed test points.
