Keysight B2902A Source/Measure Unit Repair and Calibration
The Keysight B2902A is a precision source/measure unit (SMU) — a 2-channel instrument that sources and measures voltage and current with high precision and resolution for semiconductor, device, and component characterization. As a precision source-measure instrument, its faults concentrate in the source/measure front-end, the reference, and the input/output protection.
June Company repairs and calibrates the Keysight B2902A for semiconductor, device, and materials test teams.
Common Keysight B2902A problems we fix
- Source/measure out of spec — front-end or reference drift in sourcing or measuring V/I, recalibrated against standards.
- Input front-end damage — a channel reading wrong after an over-range event, repaired.
- Low-current measurement noise — the sensitive low-range front-end, repaired.
- A channel dead — per-channel faults, repaired.
- Communication or display faults.
FAQs
My B2902A reads wrong on one channel — fixable? Yes. Front-end and reference faults are repairable, then recalibrated so sourcing and measurement are accurate and low-noise on both channels, with a NIST-traceable certificate.
Is the low-current range verified? Yes — the sensitive ranges are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
