Technical Deep Dive
Precision Signal Generation Architecture
Features "Ultra-Stable OCXO + YIG-Tuned Oscillator" design: Double-shielded oven-controlled crystal oscillator (OCXO) provides base reference stability (0.1ppb/day aging), while YIG main oscillator achieves industry-lowest phase noise. High-power amplifier stage delivers +23dBm typical output with <-70dBc harmonic distortion. Integrated pulse modulator supports <10ns rise times for radar pulse simulation.
| Technical Dimension | E8663D | Traditional Signal Generator | Advantage |
|---|---|---|---|
| Phase Noise Performance | Industry-lowest (e.g., -140dBc/Hz @10kHz offset) | -120 to -130dBc/Hz typical | 10-20dB improvement for sensitive measurements |
| Output Power | High power (+23dBm typical at 9GHz) | +10 to +15dBm typical | 8-13dB higher power reduces external amplification needs |
Radar System Test Workflow
Connection: RF output to radar receiver input, pulse modulation input to trigger source
Configuration: Set frequency to 9GHz, output power to +20dBm, enable pulse modulation (1μs width, 1kHz PRF)
Testing:
- Measure receiver sensitivity by stepping power from -100dBm to 0dBm
- Verify Doppler shift tracking with FM modulation (10kHz deviation)
- Characterize false alarm rate with injected phase noiseAnalysis: Generate detection probability curves, calculate radar range equation parameters
Power Output Boundary
Maximum output power decreases to +15dBm at 9GHz (vs +23dBm at 1GHz) (Based on typical RF amplifier characteristics). Mitigation: ① Use external amplifier for high-frequency/high-power requirements; ② Enable power calibration mode to maintain accuracy across frequency range.
