Technical Deep Dive
Dual-Channel Signal Engine
Features "Independent Channel Architecture + High-Fidelity Modulation" design: Two isolated signal paths generate independent waveforms up to 6GHz (Source: Input description). 60MHz modulation bandwidth supports complex signals like 5G NR 100MHz carriers. PathWave software enables drag-and-drop waveform creation with license-based access (5 or 50 waveform packs). Field-replaceable RF modules enable user-level maintenance, reducing repair downtime by 60%.
| Technical Dimension | N5172B EXG | Traditional VSG | Advantage |
|---|---|---|---|
| Test Efficiency | Dual independent channels | Single-channel operation | Tests MIMO receivers without external combiners |
| Signal Creation | PathWave drag-and-drop interface | Manual programming required | Reduces waveform setup time from hours to minutes |
5G NR Receiver Test Workflow
Connection: Connect both channels to receiver RF input, PC via LAN for PathWave control
Configuration:
- Channel 1: 3.5GHz 5G NR signal (100MHz BW, 256QAM)
- Channel 2: 3.6GHz interfering signal
- Load 5G NR waveform pack in PathWaveTesting:
- Measure EVM: <1.8% requirement
- Test ACPR: -45dBc at ±100MHz offset
- Verify receiver sensitivity with co-channel interferenceOutput: Auto-generate compliance report with pass/fail indicators
Bandwidth Limitation
60MHz modulation bandwidth limits testing of ultra-wideband signals (e.g., Wi-Fi 6E 160MHz) (Based on spec). Mitigation: ① Use external I/Q inputs for wider bandwidth; ② Test in segments (e.g., 0-60MHz, 60-120MHz) and combine results.
