This unit
The Stanford Research Systems CG650 is a synthesized signal generator engineered for waveform generation in precision test and laboratory applications. It delivers accurate sine, square, and triangle waveforms with low distortion and minimal jitter, making it suitable for sensitive measurements and high-speed digital system characterization.
Technical Specifications
Waveform Outputs- Sine
- Square
- Triangle Signal Characteristics
The CG650 provides low-distortion output for signal integrity in demanding applications. Square wave outputs feature fast transition times critical for digital signal testing. Jitter performance is optimized for high-speed digital systems and data acquisition circuits. Output Configuration
Multiple output levels accommodate various system interfaces and load conditions. Standard output connectors enable straightforward integration into test benches and automated systems.
Key Features
- Frequency accuracy specifications support precision timing applications
- Minimal jitter ensures reliable performance in time-sensitive measurements
- Fast square wave transitions for digital signal characterization
- Flexible output levels for diverse interface requirements
Compatibility & Integration The CG650 accepts external timebase references for enhanced frequency stability and system synchronization. Optional internal OCXO (Oven Controlled Crystal Oscillator) and Rubidium timebase upgrades are available to meet stringent stability requirements.
Manufacturer Support Stanford Research Systems backs the CG650 with a one-year warranty against defects in materials and workmanship from shipment date. Authorized SRS service facilities provide warranty service and repair support.
Stanford Research Systems CG650 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Stanford Research Systems CG650. 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 CG650 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.
