Electromagnetic Shielding Architecture
Features "Multi-Layer RF Enclosure + Optimized Waveguide Design": Conductive gaskets and double-wall construction achieve >80dB attenuation (Source: Product specifications). Broadband spiral antenna with impedance-matching network maintains VSWR <1.5:1 across 0-6GHz (Based on coupling characteristics description). Ergonomic cam-lock mechanism ensures consistent seal pressure for repeatable performance.
| Performance Metric | CMW-Z10 | Standard Shield Box | Advantage |
|---|---|---|---|
| Shielding Effectiveness | >80dB @4GHz | 60-70dB @4GHz | 20dB+ better isolation |
| Frequency Coverage | 0-6GHz (full performance) | 0-3GHz (optimized) | 100% wider bandwidth |
Wireless Receiver Sensitivity Test Workflow
Preparation: Place DUT inside chamber, connect spiral antenna to test equipment via SMA bulkhead
Sealing: Engage ergonomic latch with single hand (closing force <5N), verify RF gasket compression
Testing: Measure receiver sensitivity at -110dBm level, spiral antenna maintains consistent coupling (±0.5dB)
Analysis: Compare results with/without shielding, quantify ambient noise rejection
High-Frequency Performance Boundary
At frequencies >4GHz, shielding effectiveness gradually decreases to 60dB at 6GHz (Based on shielding physics principles). Mitigation: ① For critical >4GHz tests, add absorber material to interior surfaces; ② Position DUT at chamber center to minimize near-field effects.
