Rohde & Schwarz NRX Power Meter Repair
The Rohde & Schwarz NRX is an RF/microwave power meter — a benchtop base unit that, with a connected power sensor, measures RF and microwave power precisely for component, transmitter, and system test. As a precision RF power-measurement instrument, its faults concentrate in the sensor interface, the measurement electronics, the reference, and the display — not the multi-channel mains-power-analyzer faults its category label implies.
June Company repairs and calibrates the R&S NRX for RF/microwave engineering and test teams.
Common R&S NRX problems we fix
- Sensor-interface / input faults — the power-sensor connection not reading correctly, repaired.
- Measurement drift — the measurement electronics or reference drifting, recalibrated against standards.
- Reference-source faults — the internal power reference used to zero/cal sensors, repaired.
- Display or interface faults — repaired.
- Won’t boot or power faults.
FAQs
My NRX power readings are off — fixable? Yes. Sensor-interface and reference faults are repairable, then recalibrated so RF power measurements are accurate, with a NIST-traceable certificate.
Do you calibrate the reference? Yes — the power reference is checked against our standards. (Send the sensor with the base unit if the issue may be sensor-side.)
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
