As wireless systems become more distributed, software-defined and antenna-intensive, engineers need test architectures that evolve as quickly as the technologies they are validating,&#8221; said Kevin Schultz, NI chief technology officer with Emerson&#8217;s test and measurement business. &#8220;These capabilities reflect our commitment to helping engineers build adaptable test infrastructure that supports system-level validation and future wireless innovation.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The NI PXIe-5633 extends NI&#8217;s existing vector network analysis capabilities to four ports, helping engineers characterise more complex RF devices. As wireless systems increasingly rely on multiple RF paths, synchronised radios and distributed architectures, engineers must characterise interactions across entire systems rather than individual components in isolation. NI PXIe-5860 software enhancements support synchronisation-focused and MIMO workflows for increasingly complex wireless test requirements.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><a href=\"https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2026\/10\/4_port_PXIe-5633_PXIe-5860_VST-LO_product_shot_01-scaled.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2026\/10\/4_port_PXIe-5633_PXIe-5860_VST-LO_product_shot_01-1024x683.png\" alt=\"\" class=\"wp-image-33949\" srcset=\"https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2026\/10\/4_port_PXIe-5633_PXIe-5860_VST-LO_product_shot_01-1024x683.png 1024w, https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2026\/10\/4_port_PXIe-5633_PXIe-5860_VST-LO_product_shot_01-300x200.png 300w, https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2026\/10\/4_port_PXIe-5633_PXIe-5860_VST-LO_product_shot_01-768x512.png 768w, https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2026\/10\/4_port_PXIe-5633_PXIe-5860_VST-LO_product_shot_01-1536x1024.png 1536w, https:\/\/www.engineernewsnetwork.com\/blog\/wp-content\/uploads\/2026\/10\/4_port_PXIe-5633_PXIe-5860_VST-LO_product_shot_01-2048x1365.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\"><em>A unified RF test platform that combines measurements and scales automated workflows from validation to production<\/em><\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">Engineers can also perform S-parameter characterisation alongside modulated RF measurements through a single RF connection.
