Technical Deep Dive
Agile Threat Simulation Architecture
Features "Phase-Coherent Synthesizer + PDW Engine" design: Maintains phase coherence during 100μs frequency hops for realistic threat simulation (Source: Input description). Pulse Descriptor Word control enables individual parameter setting for each pulse (PRI, PW, RF). Ultra-low phase noise (-117dBc/Hz @20kHz offset) ensures signal purity for sensitive receivers. Export license not required (ITAR-free). Includes mmWave adapters (2.4mm/2.9mm) for 40GHz testing.
| Technical Dimension | N5191A UXG | Traditional Solution | Advantage |
|---|---|---|---|
| Threat Realism | Phase-coherent switching at 100μs | Phase breaks during frequency changes | Provides 10x more realistic frequency-hopping threat simulation |
| Pulse Flexibility | Individual PDW control per pulse | Fixed or limited pulse-to-pulse variation | Simulates complex modern radar systems with adaptive waveforms |
Electronic Warfare Test Workflow
Configuration:
- Define threat library: 50+ radar types with PDW parameters
- Set agile frequency pattern: 100 hops between 2-18GHz
- Configure pulse characteristics: PRI agility, PW modulationTesting:
- Emit complex pulse train with 100μs frequency hops
- Verify EW receiver detection/classification accuracy
- Test response time to new threat typesAnalysis:
- Measure probability of intercept (POI) >98%
- Calculate false-alarm rate <0.1%
- Generate compliance report for military standards
Frequency-Dependent Switching Boundary
Switching time increases to 500μs at 40GHz (Based on input description). Mitigation: ① Use ≤31.6GHz for critical 100μs applications; ② For mmWave testing, optimize test sequences to minimize switching frequency.
