Keysight DSOX4052A Oscilloscope Repair
The Keysight DSOX4052A is a 500 MHz InfiniiVision 4000 X-Series oscilloscope — a 2-channel scope with a capacitive touchscreen, deep memory, and a fast update rate for embedded and general-purpose debug. As a precision acquisition instrument, its faults concentrate in the analog front-end, the acquisition system, the touchscreen, and the power supply.
June Company repairs and calibrates the Keysight DSOX4052A for embedded, design, and test engineers.
Common Keysight DSOX4052A problems we fix
- A channel dead, noisy, or inaccurate — analog front-end / input-amplifier failure, often from an input overload, repaired and recalibrated.
- Bandwidth or vertical accuracy off — front-end drift, recalibrated against standards.
- Touchscreen unresponsive — the capacitive touch panel, repaired.
- Won’t boot or powers off — power-supply or board faults, repaired.
- Trigger or acquisition faults — restored.
FAQs
One channel reads wrong after an overload — fixable? Yes. Front-end damage is the most common scope fault and it’s repairable, then the channel is recalibrated so vertical accuracy and bandwidth are restored, with a NIST-traceable certificate.
Is the touchscreen repairable? Yes — touch panel repair is routine on these.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
