Technical Deep Dive
Precision Measurement Architecture
Features "Thermopile Sensor + Digital Compensation Engine" design: Broadband thermocouple elements cover 10MHz-18GHz (Source: Frequency range). Onboard EEPROM stores individual calibration factors (amplitude/linearity/temperature) 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 | Power Sensor | Traditional Sensor | Advantage |
|---|---|---|---|
| Calibration Accuracy | ±0.5% (with EEPROM compensation) | ±3-5% typical | 6-10x better measurement certainty |
| System Compatibility | Works with EPM/EPM-P/P-series meters | Limited to specific meter models | Flexible deployment across test setups |
Pulsed RF Measurement Workflow
Connection: Sensor connected between DUT and power meter via USB/GPIB
Configuration: Power meter auto-loads EEPROM calibration data (linearity/temperature/VSWR)
Measurement:
- Capture pulse envelope at 400 samples/sec
- Measure peak/average power (dynamic range: -60 to +20dBm)
- Analyze rise/fall times with 2.5ms resolutionOutput: Generate pulse profile report with power statistics
High-Frequency Measurement Boundary
Above 15GHz, calibration uncertainty increases by 0.2%/GHz (Based on typical RF sensor characteristics). Mitigation: ① Use frequency-specific calibration points; ② Enable auto-compensation in power meter software (reduces error to <0.5% up to 18GHz).
