Reliable, flexible, and high-performance! A selection guide for PXI chassis and high-speed controllers—unlock new testing possibilities.

A complete PXI system consists of a chassis, a controller, software, and peripheral modules. Among these components, the chassis serves as the core carrier and directly determines the system’s stability and reliability.

Saimai Measurement & Control is deeply engaged in the field of modular testing. Develop a full range of domestically produced, high-performance PXI chassis and a series of embedded controllers. From compact, portable models to high-end, heavy-duty ones, we offer precise solutions tailored to meet the diverse needs of semiconductor testing, consumer electronics R&D, scientific research experiments, and more!
