Technical Deep Dive
High-Density Test Architecture
Features "Modular RF Matrix + Centralized Processing" design: 32 RF ports with direct antenna connectivity eliminate external switches (Source: Input description). Precision VSA modules achieve ±0.5dB power measurement accuracy across 400MHz-6GHz range. Integrated technology modules (LTE/Wi-Fi/BT/GNSS) operate concurrently. Factory Efficiency diagnostics monitor fixture integrity in real-time, reducing downtime by 40%.
| Technical Dimension | IQxstream-M | Traditional Solution | Advantage |
|---|---|---|---|
| Test Station Footprint | 1U chassis with 32 ports | Multiple instruments + external switches (4U+) | Reduces production floor space by 75% |
| Fixture Complexity | Direct antenna connection (no external components) | Requires RF switches/combiners | Eliminates 3dB insertion loss, improves measurement accuracy |
Smartphone Manufacturing Test Workflow
Connection: Connect 8 smartphone antenna ports to 32-port system (4 ports/device), enable LTE/Wi-Fi/BT/GPS licenses
Configuration:
- Load chipset-specific IQfact+™ test plan
- Set frequency bands: LTE B1/B3/B7, Wi-Fi 2.4/5GHz, BT 5.0
- Enable Factory Efficiency monitoringParallel Testing:
- Measure LTE TX power (±0.5dB accuracy) and EVM
- Verify Wi-Fi 6 throughput at 80MHz bandwidth
- Test BT pairing and GPS cold-start TTFF
- Run LPWAN (NB-IoT) sensitivity testOutput: Auto-generate per-device report, route failures to repair station
Port Utilization Boundary
Maximum 32 ports support 8 smartphones (4 ports/DUT) or 16 IoT devices (2 ports/DUT) (Based on port count). Mitigation: ① For >8 smartphones, deploy multiple systems; ② Use port-sharing techniques for low-complexity IoT devices.
