Technical Deep Dive
Modular Signal Generation Architecture
Features "Direct Digital Synthesis + Software-Defined Modulation" design: Baseband generator creates signals up to 120MHz bandwidth (Source: Input description). Frequency extension modules cover 9kHz-6GHz via upconverters. Pre-loaded standards library (LTE-M/NB-IoT/Bluetooth® 5.x) with parametric editing (adjust EVM, frequency error). Real-time monitoring captures signal anomalies during receiver testing. Field-replaceable RF/power modules enable user-level maintenance.
| Technical Dimension | This Generator | Traditional VSG | Advantage |
|---|---|---|---|
| Frequency Flexibility | 9kHz-6GHz with modular upconverters | 100kHz-6GHz typical (excludes sub-kHz) | Tests ultra-low-frequency IoT sensors (e.g., 40kHz water meters) |
| Maintenance Cost | User-replaceable modules + 3-year warranty | Factory service required, high repair fees | Reduces downtime by 80% with $200 avg. module replacement |
Bluetooth® Receiver Sensitivity Workflow
Connection: Connect generator RF output to DUT receiver, PC via USB for control
Configuration:
- Select Bluetooth® LE 1M PHY signal
- Set frequency: 2.402GHz (Channel 37)
- Enable error injection: Add 5% random bit errorsTesting:
- Measure PER vs. input power: Sweep from -20dBm to -90dBm
- Determine sensitivity: Power level at PER=30% (e.g., -92dBm)
- Verify robustness: Test with interferer at 2.48GHz (-20dBm)Analysis: Generate bathtub curve report, flag compliance with Bluetooth® spec
Bandwidth Limitation Note
120MHz modulation bandwidth limits testing of ultra-wideband signals (e.g., Wi-Fi 7 320MHz) (Based on spec). Mitigation: ① For UWB applications, use external I/Q inputs; ② Test in segments (e.g., 0-120MHz, 120-240MHz) and combine results.
