Description

Yokogawa AQ6370C-20 Optical Spectrum Analyzer Repair and Calibration

The Yokogawa AQ6370C is a benchtop optical spectrum analyzer (OSA) — it measures the spectral content of light across the telecom/near-IR range (roughly 600–1700 nm) for testing lasers, DWDM systems, and optical components with high wavelength accuracy and wide dynamic range. As a precision optical instrument, its faults are optics, detector, and wavelength-accuracy faults — not the RF spectrum-analyzer faults its category label implies.

June Company repairs and calibrates the Yokogawa AQ6370C for fiber-optics, photonics, and laser test teams.

Common Yokogawa AQ6370C problems we fix

Dynamic range / noise-floor degradation — optical-path or detector degradation reducing dynamic range, repaired.
Wavelength accuracy off — monochromator/optical-alignment drift, recalibrated against standards.
Low sensitivity or high noise — detector or optical faults, restored.
Optical input / connector faults — damaged input optics or connector, serviced.
Scanning-mechanism or interface faults.

FAQs

My AQ6370C dynamic range or wavelength accuracy dropped — fixable? Yes. Optical-path, detector, and alignment faults are repairable, then the OSA is recalibrated so wavelength and level accuracy are restored, with a NIST-traceable certificate.

Is sensitivity verified? Yes — level accuracy and dynamic range are checked against our 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.
