Description

Keysight DSOS804A Oscilloscope Repair

The Keysight DSOS804A is an 8 GHz Infiniium S-Series oscilloscope — a high-resolution 4-channel scope (low-noise front-end, 10-bit ADC) for high-speed design, power-integrity, and signal-integrity work. As a precision high-bandwidth acquisition instrument, its faults concentrate in the analog front-end, the ADC/acquisition system, the trigger, and the display.

June Company repairs and calibrates the Keysight DSOS804A for high-speed and signal-integrity engineers.

Common Keysight DSOS804A problems we fix

Bandwidth or vertical accuracy off — front-end drift or damage degrading bandwidth/accuracy, repaired and recalibrated.
A channel dead or noisy — front-end damage from overload, repaired.
ADC / acquisition faults — acquisition errors causing bad waveforms, restored.
Trigger-system faults — unstable triggering, corrected.
Display or power faults.

FAQs

My DSOS804A bandwidth or accuracy dropped — fixable? Yes. Front-end and acquisition faults are repairable, then the scope is recalibrated so bandwidth and vertical accuracy are restored, with a NIST-traceable certificate.

Is a damaged channel repairable? Yes — front-end repair and recalibration restore the channel.

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