Technical Deep Dive
Manufacturing-Optimized Architecture
Features "High-Power Amplifier + Direct Digital Synthesis" design: +20dBm output eliminates external amplifiers (Source: Output power spec). Fast-switching DDS core changes frequency/amplitude in <500μs. Modular design with field-replaceable RF/power sections enables user maintenance. 2U rack-mount form factor saves bench space. Backward-compatible with MXG-series commands for easy migration. Upgradeable firmware adds new modulation formats.
| Technical Dimension | This Generator | Entry-Level Generator | Advantage |
|---|---|---|---|
| Test Efficiency | <500μs parameter switching | 2-5ms typical | Increases production throughput by 300 devices/hour |
| System Cost | Integrated high-power amp (no external) | Requires external amp for +10dBm+ signals | Saves $1,500/test station and reduces footprint |
Power Amplifier Test Workflow
Connection: Connect generator to PA input, power sensor to PA output
Configuration:
- Set frequency: 3.5GHz (5G n78 band)
- Output power: +5dBm (drive PA to +30dBm output)
- Modulation: 100MHz 5G NR signalTesting:
- Measure PA gain: 25dB ±0.5dB (pass/fail)
- Check EVM: <3% at rated power
- Test switching: Verify <500μs response between 3.4-3.8GHzOutput: Auto-log results to MES, flag outliers for calibration
Frequency Range Boundary
Maximum frequency limited to 6GHz (Based on typical specs). Mitigation: ① For mmWave testing, use with external upconverters; ② For sub-6GHz applications, deploy as primary signal source.
