| Waveform Flexibility | 800MSa memory + MATLAB integration | ≤64MSa typical | Stores 12x more test scenarios for complex devices |
Cellular PA Production Test Workflow
Connection: Connect PA to generator RF output, power sensor to PA output
Configuration:
- Load 5G NR FR1 waveform (100MHz BW, 256QAM)
- Set frequency: 3.5GHz, initial power: -10dBm
- Enable list mode: 10 power levels from -10 to +20dBmTesting:
- Measure gain flatness: ±0.5dB across band
- Verify ACPR: < -45dBc at +23dBm output
- Capture EVM: <3% at P1dB compression pointOutput: Auto-bin devices based on results, generate calibration certificate
Power Output Limitation
Output power decreases to +15dBm at 6GHz (Based on typical RF characteristics). Mitigation: ① For high-power mmWave testing, add external amplifiers; ② Use at ≤4GHz for maximum +23dBm performance.
