EG&G Princeton 9503 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the EG&G Princeton 9503. Calibration covers full-scale sensitivity accuracy at 1 V and at each decade below the maximum range, time constant accuracy, phase offset and phase noise verification, reference frequency range and accuracy, dynamic reserve verification, and noise floor (V/√Hz) measurement. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common EG&G Princeton 9503 faults: keypad ribbon cable wear (intermittent key response), DSP board failure, reference input circuit failure, trim pot drift on analog models. Stanford Research SR810/830 most common fault is front-panel keypad ribbon cable wear causing intermittent key response. DSP board failure is rare but results in loss of lock and incorrect readings. EG&G 5204/5210 analog demodulator units most commonly develop trim pot drift requiring phase and offset recalibration.
