This unit
The Stanford Research Systems SG382 is a 2 GHz analog RF signal generator delivering high-resolution frequency synthesis across DC to 2.025 GHz via dual outputs. Built on Rational Approximation Frequency Synthesis architecture, it achieves 1 µHz frequency resolution, -116 dBc/Hz phase noise at 20 kHz offset (1 GHz carrier), and 1 × 10⁻¹¹ frequency stability. The instrument supports six modulation types
AM, FM, ΦM, PM, Pulse, and Blank - with internal waveform sources and external input capability, making it suitable for precision RF characterization and demanding test environments.

Stanford Research Systems SG382 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Stanford Research Systems SG382. Calibration covers output frequency accuracy, output power level accuracy across the full frequency range, AM/FM/PM/pulse modulation accuracy, harmonic and spurious output levels, and phase noise floor verification. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Stanford Research Systems SG382 faults: YIG oscillator failure (no output or loss of lock), step attenuator wear (output drops or steps at set attenuation), ALC loop failure (uncontrolled output power), I/Q modulator assembly failure. HP/Agilent 836xx series most common faults are YIG oscillator failure and step attenuator contact wear causing output steps or drops at specific attenuation settings. Keysight E4428C/E4438C units most commonly develop ALC loop failure and I/Q modulator assembly faults. YIG oscillator replacement and attenuator service are stocked repairs.
