Case Study: Leading Semiconductor Automated Test Equipment Service Provider achieves 5G readiness and improved test consistency with Keysight's M9421A VXT PXIe vector transceiver

Semiconductor ATE Vendor Prepares for 5G

Leading Semiconductor Automated Test Equipment Service Provider needed a next‑generation RF ATE solution to address 5G NR challenges—mmWave, OTA, MIMO, wider bandwidths, evolving standards—while remaining backward‑compatible with 2G/3G/4G and delivering tight consistency and reliability across high‑volume OSAT systems. The vendor evaluated Keysight and its M9421A VXT PXIe vector transceiver as a potential fit for these requirements.

Keysight supplied the M9421A VXT (four‑slot PXIe vector transceiver, 60 MHz–6 GHz, up to 160 MHz modulation/analysis bandwidth) plus software and direct R&D support; the unit passed two validation rounds (lab and high‑volume prototype installation). As a result, Keysight’s solution improved measurement quality and consistency, enabled real‑world production use, expanded the customer base for the Leading Semiconductor Automated Test Equipment Service Provider, and helped increase its market share and leadership position in compact ATE for 5G.
