Technical Deep Dive
Precision Measurement Architecture
Features "Thermocouple Sensor + Digital Compensation" design: Broadband thermocouple elements cover 10MHz-6GHz (Source: Frequency range). Onboard EEPROM stores calibration factors (linearity/temperature/VSWR) enabling ±0.5% accuracy. Low-VSWR RF path (<1.5:1) minimizes measurement errors in mismatched systems. High-speed ADC enables 400Hz sampling for transient capture (Based on measurement speed).
| Technical Dimension | E9301A | Traditional Sensor | Advantage |
|---|---|---|---|
| Calibration Accuracy | ±0.5% (with EEPROM compensation) | ±3-5% typical | 6-10x better measurement certainty |
| Measurement Speed | 400 readings/sec | 50-100 readings/sec | 4-8x faster for production testing |
Cellular Base Station Test Workflow
Connection: Sensor connected to base station RF output via coaxial cable
Configuration: Power meter auto-loads EEPROM calibration data (linearity/temperature)
Testing:
- Measure average power during 5G NR transmission (400 samples/sec)
- Verify power control accuracy across -40dBm to +20dBm range
- Capture power ramp-up/down characteristicsAnalysis: Generate pass/fail report with power vs time graph
High-Power Measurement Boundary
Continuous exposure to >+20dBm signals may cause sensor damage (Based on power range specification). Mitigation: ① Use external attenuator for >+20dBm measurements; ② Enable auto-power-down feature when exceeding +23dBm.
