Keysight Technologies shares rose Tuesday as investors reacted to a newly disclosed partnership tied to satellite connectivity testing. Keysight teamed up with Skylo to build a certification program for 3GPP 5G Release 17 Non‑Terrestrial Network (NTN) chipsets, modules, and devices intended for use on Skylo’s network, putting Keysight directly in the workflow as device makers push to validate interoperability and performance for NTN deployments.

NTN is moving from standards work into commercialization, and certification is a key gating step for broader adoption across the chipset, module, and device ecosystem. For Keysight, certification programs typically translate into demand for test platforms, automation software, and services used across multiple customers and product cycles, reinforcing its position as a picks-and-shovels supplier to next-generation connectivity buildouts.

Investors will be watching for follow-on announcements that expand the program’s scope—such as additional device partners, lab availability, or operator endorsements—as well as any indications that NTN testing is becoming a measurable contributor to orders alongside broader AI/data-center-driven wireline strength. Near term, the next catalyst risk is whether momentum holds without incremental contract wins or estimate revisions, particularly after the stock’s sharp rerating in recent months.
