This unit
The Stanford Research CG647 is a clock and signal generator that produces CML (Current Mode Logic) and NIM (Nuclear Instrumentation Module) outputs spanning frequencies up to 2050 MHz. Built for demanding scientific, research, and industrial applications, it delivers exceptional frequency accuracy and stability required in precision timing systems.
Technical Specifications
Output Signal Characteristics- Signal Type: CML / NIM
- Frequency Range: Up to 2050 MHz
- Frequency Accuracy: Exceptional
- Frequency Stability: Exceptional Input Interface
- Line Receiver Input: LVDS clocks via RJ-45 connector
Key Features
- Direct CML and NIM output generation for nuclear and high-frequency instrumentation
- LVDS clock input acceptance enables flexible system architecture
- RJ-45 input connector for standardized connectivity
Typical Applications
- Nuclear instrumentation and detection systems
- High-frequency timing and synchronization in research environments
- Precision clock distribution in scientific instruments
- Industrial timing applications requiring stable signals to 2050 MHz
Compatibility & Integration The CG647 integrates with CG646-CG647 line receivers, which accept differential LVDS clock inputs and convert them to CML or NIM outputs delivered on SMA connectors. This architecture allows flexible system design where the CG647 is a signal source feeding downstream CML/NIM-compatible instrumentation.

Stanford Research CG647 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Stanford Research CG647. 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 CG647 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.
