Technical Deep Dive
Cross-Correlation Signal Processing Architecture
Features "Dual-Reference Receiver + Advanced DSP" design: Two independent measurement paths with cross-correlation algorithm cancel uncorrelated noise (Source: Phase noise measurement principles). Achieves noise floor <-180dBc/Hz at 10kHz offset (40dB lower than traditional analyzers). Real-time transient capture uses 100MS/s ADC with video trigger (1ns resolution) to detect frequency jumps >1µs duration. Jitter analysis integrates phase noise data from 12mHz to 40MHz offset.
| Technical Dimension | E5052B SSA | Traditional Spectrum Analyzer | Advantage |
|---|---|---|---|
| Phase Noise Sensitivity | <-180dBc/Hz @10kHz offset | -140dBc/Hz @10kHz offset | 40dB improvement for low-noise oscillators |
| Transient Capture | Frequency/phase/power simultaneous (100MS/s) | Power-only (1MS/s typical) | 100x higher resolution for fast events |
Radar LO Stability Test Workflow
Connection: E5052B RF input to radar local oscillator output, trigger input to radar pulse sync signal
Configuration: Multi-window setup - Phase noise plot (1-100MHz offset), frequency transient (video trigger on pulse edge), phase/power vs time
Analysis:
- Verify phase noise <-160dBc/Hz @10kHz (meets radar clutter rejection spec)
- Capture frequency settling within 5µs after pulse trigger (0.1ppm stability)Reporting: Auto-generate MIL-STD-461 compliance report with pass/fail markers
Measurement Performance Boundary
Cross-correlation phase noise measurement requires >30sec averaging for offsets <1Hz (Based on signal processing requirements). Mitigation: ① For production testing, use fast mode (5sec average with 3dB sensitivity penalty); ② Enable "Smart Averaging" to dynamically adjust integration time per offset frequency.
