GenRad 1644-A — Repair & Calibration Service

Aumictech offers NIST-traceable calibration and repair for the GenRad 1644-A. 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 GenRad 1644-A 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.

This GenRad 1644-A is listed at $650. Calibration is available separately from $450. Contact us for volume pricing or if you need multiple units.

GenRad 1644-A calibration cost

NIST-traceable calibration for the GenRad 1644-A is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument 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.. Turnaround is 1 to 3 business days after receipt. See full calibration details →
