Common GenRad 1650B 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.

GenRad 1650B calibration cost

NIST-traceable calibration for the GenRad 1650B 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 →
