Keysight B2983A Picoammeter Repair
The Keysight B2983A is a precision picoammeter / electrometer — it measures extremely small currents (down to the femtoamp/picoamp level) for low-current applications like leakage, sensor, and materials measurement, with a battery-operable design for low-noise work. As an ultra-low-current measurement instrument, its faults concentrate in the sensitive input front-end, the electrometer amplifier, and input protection.
June Company repairs and calibrates the Keysight B2983A for low-current measurement, materials, and research teams.
Common Keysight B2983A problems we fix
- Low-current accuracy out of spec — electrometer/front-end drift that skews fA–pA readings, recalibrated against standards.
- Input front-end damage — the sensitive input damaged (often by an over-range current or voltage), repaired.
- Excess noise / unstable readings — input or shielding faults raising the noise floor, corrected.
- Input protection faults — repaired.
- Display or interface faults.
FAQs
My low-current readings drifted or got noisy — fixable? Yes. The electrometer front-end is repairable and recalibrated, then verified so fA/pA-level measurements are accurate and stable, with a NIST-traceable certificate.
Is it calibrated at low ranges? 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.
