Technical Deep Dive
Advanced Vector Synthesis Architecture
Features "Direct Digital Synthesis + Ultra-Low-Noise Upconversion" design: Baseband section with 16-bit DAC generates 80MHz bandwidth signals (IQ modulation error <0.5°), upconverted via phase-locked YIG oscillators achieving -143dBc/Hz phase noise at 1GHz (Source: Input specification). Integrated 80MHz AWG enables real-time complex waveform generation. PathWave software supports radar pulse building, multi-tone signals, and standards-compliant waveforms (5G NR, SATCOM).
| Technical Dimension | E8267D PSG | Traditional VSG | Advantage |
|---|---|---|---|
| Phase Noise | -143dBc/Hz @10kHz offset (1GHz) | -120 to -130dBc/Hz | 13-23dB improvement for sensitive receiver testing |
| Signal Complexity | Integrated 80MHz AWG + real-time generator | Requires external arbitrary waveform generator | Single-instrument solution reduces setup complexity |
Radar Warning Receiver Test Workflow
Configuration: PathWave software loads "Pulse-Doppler Radar" template → configures pulse width (1µs), PRF (10kHz), FM chirp (80MHz)
Connection: RF output to receiver under test, sync signal to oscilloscope
Testing:
- Generate threat radar signals across 2-18GHz band
- Measure receiver detection probability at -80dBm input level
- Verify false alarm rate with injected phase noiseAnalysis: Generate PDF report with pulse characteristics, detection statistics, and jitter analysis
Bandwidth Limitation Mitigation
Maximum 80MHz modulation bandwidth restricts ultra-wideband radar simulations (e.g., >100MHz chirp) (Based on input specification). Mitigation: ① Use external AWG for >80MHz signals (requires complex calibration); ② Employ frequency-hopping techniques to simulate wider effective bandwidth.
