Keysight MSOX4022A Oscilloscope Repair
The Keysight MSOX4022A is a 200 MHz InfiniiVision 4000 X-Series mixed-signal oscilloscope — 2 analog plus 16 digital channels with a capacitive touchscreen and fast update rate for embedded and mixed-signal debug. As a precision acquisition instrument, its faults concentrate in the analog front-end, the acquisition system, the trigger, and the touchscreen.
June Company repairs and calibrates the Keysight MSOX4022A for embedded and test engineers.
Common Keysight MSOX4022A problems we fix

FAQs
My MSOX4022A bandwidth or a channel is off — 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 the touchscreen repairable? Yes — touch panel repair is routine.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
