The M9101A is a high-density, 64-channel multiplexer in a single PXI module. This module will route many different channels to a single point. The switches can operate in a break-before-make mode, ensuring no two points are connected at the same time, or, if needed, multiple channels can be connected simultaneously. This module is ideal for routing multiple analog signals to a measurement device in automated test environment (ATE) or data acquisition systems. Each channel switches a high and a low for 2-wire switching. The high-speed, long-life reed relays are capable of switching up to 100Vrms, with up to 10W of power. Connection options include the durable connector block or the standard cable connections.

Software drivers support most common programming environments such as Visual Studio®, C, C++, C#, Visual Basic, MATLAB® and LabVIEW™. The high-quality switches with durable connections ensure trustworthy measurements, and, with the high-speed reed relays, product throughput increases. Installation and configuration are fast and easy With Keysight Connection Expert and soft front panels.
