Description

Keysight MSOS804A Oscilloscope Repair

The Keysight MSOS804A is an 8 GHz Infiniium S-Series mixed-signal oscilloscope — a 4 analog plus 16 digital channel scope with a high-resolution ADC and deep analysis for high-speed serial, signal-integrity, and mixed-signal work. As a precision high-bandwidth acquisition instrument, its faults concentrate in the analog front-end, the ADC/acquisition system, the trigger, and the logic-acquisition hardware.

June Company repairs and calibrates the Keysight MSOS804A for high-speed design and signal-integrity teams.

Common Keysight MSOS804A problems we fix

FFT / eye-diagram analysis faults — acquisition or trigger faults degrading FFT/eye results, repaired and recalibrated.
A channel dead, noisy, or inaccurate — analog front-end damage from overload, repaired and recalibrated.
Digital (MSO) channels not working — the logic-acquisition hardware, restored.
Trigger-system faults — unstable or wrong triggering, corrected.
Display or power faults.

FAQs

My FFT/eye results or a channel look wrong — fixable? Yes. Front-end, acquisition, and trigger faults are repairable, then the scope is recalibrated so capture and vertical accuracy are restored, with a NIST-traceable certificate.

Do you handle the digital channels? Yes — the logic-acquisition hardware is diagnosed and repaired.

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.
