For precise and time-saving compliance testing of the latest generation PCIe 5.0 and 6.0 cables and connectors in line with PCI-SIG specifications, Rohde & Schwarz is developing a new R&S ZNrun vector network analyzer automation suite option. For a fully automated verification of a PCIe x8 cable, for instance, the software controls a setup with R&S ZNB vector network analyzer plus scalable R&S OSP switch matrix configuration, creating a multiport VNA solution with 64 test ports. The solution reduces testing times for PCIe x8 cables to just a few minutes for complete test runs with all Thru and all crosstalk combinations plus corresponding metric calculations for Pass/Fail evaluations. By comparison, manual testing takes several hours and involves major risk of connection errors by test engineers.
