Technical Deep Dive
Measurement System Architecture
Features "High-Speed Acquisition + Digital Signal Processing" architecture: E9320 sensors capture RF power with 20MS/s sampling (Source: Input specs), E4416A meter performs real-time peak/average/PAR calculations, time-gating enables precise burst power measurements (e.g., TDMA slots). Free Analyzer Software provides pulse parameter extraction and statistical analysis (rise/fall time, duty cycle, CCDF).
| Capability | E4416A + E9320 | Basic Power Meter | Advantage |
|---|---|---|---|
| Pulsed Signal Analysis | Time-gated measurements with 20MS/s resolution | Average power only | Captures transient power events accurately |
| Standard-Specific Testing | 8 wireless presets (auto-configuration) | Manual configuration required | 70% faster setup for compliance testing |
GSM Burst Power Measurement Workflow
Configuration: Select "GSM" preset → auto-sets time-gating parameters (577μs slot duration), PAR measurement mode
Connection: E9320 sensor to DUT RF output, USB/LAN to control PC running Analyzer Software
Analysis:
- Time-gated power measurement captures burst power (30dB dynamic range)
- Analyzer Software computes rise/fall time (≤28μs), power vs time template complianceReporting: Generates PDF report with pulse profile, CCDF curve, and pass/fail status
Measurement System Limitations
When measuring signals >6GHz, E9320 sensor sensitivity decreases by 0.5dB (Based on typical power sensor frequency response). Mitigation: ① Use E9321A sensor for higher frequencies; ② Apply correction factors in Analyzer Software for frequencies >6GHz.
