Keysight MSOX4104A Oscilloscope Repair
The Keysight MSOX4104A is a 1 GHz InfiniiVision 4000 X-Series mixed-signal oscilloscope — 4 analog plus 16 digital channels, a capacitive touchscreen, and a fast update rate for embedded and mixed-signal debug. As a precision acquisition instrument, its faults concentrate in the analog front-end, the trigger system, the display, and the power supply.
June Company repairs and calibrates the Keysight MSOX4104A for embedded and test engineers.

FAQs
My scope won’t trigger reliably — fixable? Yes. Trigger-system faults are repairable and recalibrated, then verified so triggering is stable across modes, with a NIST-traceable certificate.
Are the digital channels repairable? Yes — the MSO logic channels are serviced and verified.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
