Keysight DAQM908A 40-Channel Single-Ended Multiplexer

Overview

The Keysight DAQM908A is a 40-channel single-ended multiplexer module providing the highest signal-switching density for common-low applications. Each module switches 40 one-wire inputs with support for all two-wire internal measurements except current. The module's low connection floats up to 300V, enabling testing of devices with elevated common-mode voltages. Scan rates of up to 100 channels per second are supported, making this module ideal for rapid automated test sequences.
