Technical Deep Dive
Dual-Channel Architecture
Features "Independent Channel Processing + Shared Control System" design: Two isolated measurement paths with dedicated ADC/DSP per channel (Source: Power meter architecture standards), enabling true simultaneous measurement without channel crosstalk. Shared control unit manages GPIB/RS232 communication and battery management, while maintaining code compatibility with 438A power meters through emulation firmware.
| Technical Dimension | E4419B | 438A Power Meter | Advantage |
|---|---|---|---|
| Channel Independence | True simultaneous measurement | Multiplexed measurement | 100% concurrency for time-synchronized measurements |
| Measurement Speed | 100Hz/channel (200Hz total) | 50Hz total (both channels) | 300% faster data acquisition |
MIMO Antenna System Test Workflow
Connection: Channel 1 to TX1 antenna port, Channel 2 to TX2 antenna port, GPIB to control PC
Configuration: Set both channels to 100Hz sampling, load "MIMO Power Balance" test template
Execution:
- Simultaneous power measurement during beamforming sequence
- Real-time calculation of power ratio (TX1/TX2) with ±0.5dB tolerance checkAnalysis: Generate correlation graph of dual-channel power over time, flag deviations >1dB
Battery Performance Boundary
Continuous 100Hz dual-channel operation reduces battery life to 2.5 hours (vs 4hr at 50Hz) (Based on power consumption characteristics). Mitigation: ① Reduce sampling rate to 50Hz when full speed isn't required; ② Enable power-saving mode (auto-sleep after 5 minutes idle).
