Case Study: Japanese Medical Equipment Company halves MRI service time and boosts RF shielding detection with Keysight FieldFox

Handheld Analyzer Improves MRI Performance

The Japanese Medical Equipment Company was struggling to service and tune MRI RF coils in hospitals because technicians had to bring a benchtop vector network analyzer into MRI rooms, power it from another room and shuttle back and forth to avoid magnetic interference. To solve this, the company adopted Keysight’s N9918A FieldFox handheld RF and microwave analyzer.

Keysight’s FieldFox provided a portable VNA/spectrum analyzer with real‑time spectrum analysis, large readout, channel scanning and data‑logging features, allowing in‑room tuning and fast site surveys. As a result, Keysight’s solution cut service times by 50%, increased discovery of RF‑shielding issues by 30%, and made accurate on‑site surveys practical, reducing downtime and improving MRI maintenance efficiency.
