Description

Rohde & Schwarz FSW43 Spectrum Analyzer Repair

The Rohde & Schwarz FSW43 is a high-end signal and spectrum analyzer covering up to 43.5 GHz — a top-tier bench analyzer with wide analysis bandwidth and very low phase noise for demanding microwave, radar, and wideband signal work. As a precision microwave receiver, its faults concentrate in the RF front-end (mixer, attenuator, YIG/LO), the synthesizer, the IF/ADC path, and the display.

June Company repairs and calibrates the R&S FSW43 for microwave, radar, and advanced-signal test teams.

Common R&S FSW43 problems we fix

Mixer replacement — front-end mixer damage (often from overload) degrading sensitivity and accuracy, replaced.
YIG-oscillator recalibration — the tuned oscillator drifting or failing, repaired and recalibrated.
Attenuator faults — the input step attenuator not switching correctly, repaired.
Amplitude or frequency accuracy off — front-end or synthesizer drift, recalibrated against standards.
Display or interface faults.

FAQs

My FSW43 sensitivity dropped — fixable? Yes. Mixer, YIG, and attenuator faults are repairable and recalibrated, then verified so amplitude and frequency accuracy are restored across the range, with a NIST-traceable certificate.

Is it calibrated across its range? Yes — verified against our reference standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.

Shipping & Returns

Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.

Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.

Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.

Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.

Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
