Technical Deep Dive
High-Speed Measurement Architecture
Features "Wideband Detector + GPIB-Optimized Interface" design: 5MHz video bandwidth enables accurate measurement of CDMA/W-CDMA signals (Source: Input description). High-speed ADC and dedicated DSP achieve 1000 calibrated readings/sec over GPIB. Precision Type-N connector maintains <1.5:1 VSWR up to 6GHz. EEPROM stores temperature/linearity/bandwidth correction data for ±0.5dB measurement accuracy.
| Technical Dimension | Power Sensor | Traditional Sensor | Advantage |
|---|---|---|---|
| Measurement Speed | 1000 readings/sec | 100-400 readings/sec | 2.5-10x faster throughput |
| Signal Processing | Real-time bandwidth/temperature compensation | Manual correction required | Eliminates post-processing time |
CDMA Power Control Test Workflow
Connection: Sensor connected to CDMA handset RF output via precision Type-N cable
Configuration: Power meter auto-loads EEPROM calibration data (bandwidth/temperature)
Testing:
- Measure power control steps at 1000 samples/sec
- Verify open-loop power control response time
- Capture fast power transients during handoffAnalysis: Generate power vs time plot with 1ms resolution
GPIB Speed Boundary
1000Hz speed requires GPIB interface (RS232/USB limited to 200Hz) (Based on interface specification). Mitigation: ① Use GPIB for high-speed applications; ② For non-GPIB environments, enable averaging mode (reduces speed to 100Hz but improves accuracy).
