| Parameter | Specification | Application Value |
|---|---|---|
| TRX Channels | 4 channels (6GHz bandwidth each) | Simultaneous 4x4 MIMO testing for WiFi 6/5G |
| Port Configuration | 2 full-duplex + 2 half-duplex or 4 full-duplex per TRX | Flexible testing of TDD/FDD devices |
| DUT Capacity | Up to 32 devices with MPA | Massively parallel production testing |
Core Application Scenarios
5G Smartphone Production Lines — Test 32 devices simultaneously with Qualcomm-approved 5G NR measurements (Based on Qualcomm QDART approval)
WiFi 6E Access Point Validation — 4x4 True-MIMO testing with 160MHz bandwidth (Based on 6GHz channel bandwidth)
Leasing Scenario Technical Adaptation
Production Scalability — Start with 1 TRX channel, add channels as volume grows (Reduces initial investment 60%)
Multi-Technology Future-Proofing — Software-upgradable for emerging standards (Reduces equipment refresh costs)
Technical Deep Dive
Scalable Test Architecture
Features "Modular TRX Engine + Distributed Signal Processing" design: Each TRX channel contains independent vector signal generator/analyzer pairs (6GHz instantaneous bandwidth) with <0.1dB amplitude flatness (Source: Industry-proven platform). Multiport adapter (MPA) technology enables 32:1 device multiplexing with <100ns switching time. PathWave automation framework supports single-acquisition multi-measurement sequences (e.g., capture EVM/ACPR/spectral mask in one sweep).
| Technical Dimension | E6640A EXM | Traditional Test Set | Advantage |
|---|---|---|---|
| Parallel Testing Capacity | 32 DUTs via MPA | 4-8 DUTs typical | 400% higher throughput |
| MIMO Testing | 4x4 True-MIMO (160MHz BW) | 2x2 switched-MIMO (80MHz BW) | Full spatial stream analysis for WiFi 6/6E |
5G mmWave Device Production Test Workflow
System Configuration: Connect 8 phased array modules to MPA, configure 4 TRX channels for 28/39GHz bands
Calibration: Run automated beamforming calibration sequence (PathWave software)
Parallel Testing:
- Simultaneous TX power/EVM measurement on 8 DUTs
- Beam steering verification across 120° FoV
- 5G NR FR2 compliance check (ACLR < -30dBc)Output: Auto-generate device-specific performance reports, flag modules with beam anomalies
Frequency Band Boundary
MPA technology supports up to 6GHz (Based on TRX bandwidth). For mmWave testing (>24GHz), external frequency converters required. Mitigation: ① Use integrated mmWave modules (option); ② For FR2 production, deploy EXM with OTA chambers.
