Technical Deep Dive
High-Speed Architecture
Features "Dual-Path Signal Processing + Optimized Range Switching" architecture: Dedicated DSP for E-series sensors minimizes range switching to single point (Source: Input description), parallel ADC channels enable 200Hz sampling over GPIB. 8480 series sensors bypass range switching entirely through analog autoranging, achieving 2x speed improvement over 437B meters (Based on performance comparison).
| Technical Dimension | E4418B | 437B Power Meter | Advantage |
|---|---|---|---|
| Measurement Speed | 200 readings/sec (GPIB) | 100 readings/sec | 100% faster data acquisition |
| Range Switching | No delay (8480 sensors), 1 switch point (E-series) | Multi-point switching (delays) | Eliminates 90% of range-switching latency |
Automated Test System Integration Workflow
Connection: GPIB interface to ATE controller, E-series sensor to DUT RF output
Configuration: Send SCPI commands "CONF:POW:AC" → set averaging (10ms window)
Execution: Continuous power measurement at 200Hz during DUT TX burst (captures power ramps/transients)
Analysis: Real-time power compliance check (e.g., ±0.5dB tolerance), auto-log outliers
Speed Performance Boundary
Maximum 200Hz speed requires GPIB interface + E-series sensors (RS232 interface limits to 50Hz). Mitigation: ① Use GPIB for high-speed applications; ② For RS232 environments, enable "Fast Mode" in settings (reduces accuracy by 0.5% but increases speed to 100Hz).
