The new PXIe‑5633 adds a fourth RF port to Emerson’s PXI test platform, giving engineers a single piece of hardware to probe up to four antenna channels at once. In practice that translates to a 4‑port S‑parameter sweep that covers the full 2–6 GHz band used by most 5G automotive radios.
A key selling point is the synchronisation‑ready software on the PXIe‑5860, which coordinates the four channels in real time. For a car manufacturer testing a 4×4 MIMO 5G module, that means a single lab bench can deliver both the raw channel‑to‑channel interaction data and the modulated LTE‑5G traffic pattern.
The move cuts down the need for separate VNAs and vector signal generators, a common pain point in production lines. OEMs that have relied on a mix of Keysight and Anritsu gear now can consolidate their test chain, reducing rack space and test cycle time.
Regulators are tightening V2X requirements in India and the EU, pushing for 5G‑capable infotainment and safety‑critical communication. Emerson’s platform lets labs verify compliance with the latest ETSI and ITU‑R standards, easing the certification gap for next‑generation autonomous vehicles.
Emerson will showcase the four‑port VNA at European Microwave Week in Brussels, booth A40B, where a live 4×4 MIMO demo will run on the PXIe‑5860. The hardware is already shipping to test labs worldwide, with full production‑line integration expected by Q3 2025.
For anyone buying a new testing kit, the takeaway is that a 4‑port VNA with built‑in MIMO sync can replace an entire rack of legacy gear, cutting both cost and footprint in the critical V2X validation phase.
