Agilent / Keysight E4990A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight E4990A. Calibration covers impedance magnitude accuracy at 100 Hz, 1 kHz, 10 kHz, and 100 kHz, dissipation factor (D) and quality factor (Q) accuracy, phase angle accuracy, open and short compensation verification, and cable length compensation. HP/Keysight 4284A additionally verified at 1 MHz.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight E4990A faults: GPIB interface board failure, display failure, guard terminal switch contact wear, oscillator calibration drift on older analog bridges. HP 4284A and 4285A most common faults are HPIB interface board failure and display contrast loss. The internal oscillator and vector measurement circuits are highly stable and rarely fail. Wayne Kerr and GenRad bridge instruments may develop switch contact wear on decade resistance/capacitance dials.
