When you need to measure advanced S-parameters with a fast, low-cost and easy-to-use test solution, the Digital Interconnect Test System gives you a significant edge. It provides a full 32-port vector network analyzer (VNA) configured within a single PXI chassis – ideal for high-speed cable testing. And lets you test any linear passive interconnect faster and easier, including backplanes, connectors and PCBs. Sharpen your edge with Keysight’s Digital Interconnect Test System that enables signal integrity characterization of multiport interconnect products.

The Keysight Physical Layer Test System (PLTS) Software lets you perform multi-domain analysis. Customized software is included to help you cut your test time in half. To facilitate evaluation and integration in your test environment, you can use the test code examples provided that are designed to increase test throughput with a user-friendly graphical user interface.
