Keysight B2911A Source/Measure Unit Repair and Calibration
The Keysight B2911A is a precision source/measure unit (SMU) — it sources and measures voltage and current simultaneously with high resolution (down to fA/µV levels) for characterizing semiconductors, components, and materials. As a precision source-and-measure instrument, its faults concentrate in the source, the low-level measurement front-end, and the input/output protection.
June Company repairs and calibrates the Keysight B2911A for semiconductor, component, and materials test teams.
Common Keysight B2911A problems we fix
- Source or measure out of spec — source/measure drift, recalibrated against standards so V/I sourcing and low-level measurement are accurate.
- Low-current measurement faults — the sensitive fA/pA front-end damaged (often from an overload), repaired.
- Output won’t reach setpoint or trips — source-stage or protection faults, repaired.
- Won’t communicate — the remote interface, restored.
- Display or control faults.
FAQs
My low-current measurements are off after an overload — fixable? Yes. The sensitive measurement front-end is repairable, then the SMU is recalibrated so source and low-level measurement accuracy are restored, with a NIST-traceable certificate.
Are source and measure both verified? Yes — both 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.
