Core Application Scenarios

• IoT Module Validation — Test Cat-M1/NB-IoT RF performance with 3GPP auto-PASS/FAIL (Based on measurement capability)

• Smartphone Power Optimization — Conducted + OTA power consumption testing during VoLTE calls (Based on functional testing)

Unified Test Architecture

Features "Modular RF Engine + Integrated Windows PC + Smart GUI" design: Built-in RF front-end handles up to 4x4 MIMO without external combiners (Source: Input description). Windows 7 PC core enables standalone IP throughput/VoLTE testing. Next-gen touch GUI with swipe controls and parameter bookmarking reduces setup time 70%. Backward-compatible remote commands (GPIB/Ethernet) allow reuse of MT8820C automation scripts. ATS sample tool automates 3GPP test cases with one-click execution.

IoT Module RF Validation Workflow

1. Connection: Connect NB-IoT module to RF port, enable conducted mode

2. Configuration:
   - Select "3GPP NB-IoT" test profile from one-touch menu
   - Bookmark key parameters (e.g., 23dBm output power)
   - Enable auto PASS/FAIL with ±3dB tolerance

3. Testing:
   - Run TRX measurements: Output power, EVM, frequency error
   - Verify power consumption in PSM mode (<5μA)
   - Execute end-to-end IP throughput test via built-in Windows PC

4. Output: Generate compliance report with flagged outliers

Frequency Scalability Limit

Maximum 6CC requires 3 synchronized units (Based on MIMO configuration). Mitigation: ① For cost-sensitive projects, start with single-box 2CC 4x4 MIMO; ② Use modular upgrade path to add units as needed.
