Intelligent Test Architecture
Features "Superheterodyne Reception + Reflection Testing" design: 9kHz-4GHz superheterodyne receiver chain (Dynamic range >100dB, Estimated from spectrum analyzer standards). Built-in VSWR bridge enables single-port reflection testing (VSWR measurement accuracy ±0.05, Based on product features). Test manager supports automatic execution of 20 predefined measurements (Configuration time ≤3 seconds, Core product feature). Cursor demodulation simplifies complex signal analysis (Demodulation time ≤5ms, Based on product functionality).

Antenna System Test Workflow
Connection: Single-port direct connection to antenna system with auto-interface recognition
Configuration: Load pre-set VSWR test template, complete setup in 3 seconds
Analysis: Simultaneous spectrum analysis + reflection characteristics measurement
Output: Generate test report with PASS/FAIL indicators
High-Frequency Reflection Test Boundary
Cable phase shift may cause ±0.1 VSWR measurement error when testing >3.5GHz (Estimated from reflection test characteristics). Mitigation: ① Enable phase compensation (improves accuracy to ±0.02); ② Use phase-stable test cables (provided with rental).
