This unit
The Stanford Research Systems SR510 is a single-phase lock-in amplifier that detects and measures weak AC signals buried in significant noise through precision analog demodulation. Using a sine-wave multiplier, the instrument translates input signals down to DC, enabling subsequent filtering and amplification with exceptional sensitivity across a broad frequency range.

Key Features Precision analog sine-wave multipliers eliminate spurious harmonic responses. Dual notch filters suppress 60 Hz and 120 Hz interference. Selectable stability modes (5 ppm/°C to 500 ppm/°C) accommodate different operating conditions. Single-ended or differential voltage inputs with picoampere-level current sensitivity. Phase-locked detection at fundamental or second harmonic enables flexible measurement configurations.
Typical Applications Phase-sensitive detection of modulated signals. Characterization of low-impedance or high-impedance samples. Noise reduction in spectroscopy and materials analysis. Lock-in measurement of AC parameters in semiconductor and condensed-matter research.

Stanford Research Systems SR510 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Stanford Research Systems SR510. 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 Stanford Research Systems SR510 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.
