High-Precision Measurement Workflow
Connection: Direct connection to DUT with auto-impedance matching
Configuration: Select 28MHz analysis bandwidth, enable digital filtering
Capture: 200Msample memory records transient signals
Analysis: Digital filters achieve ±0.3dB amplitude accuracy
High-Frequency Measurement Boundary
Waveguide conversion loss may cause ±1.2dB measurement error when testing >35GHz (Estimated from mmWave test characteristics). Mitigation: ① Enable loss compensation algorithm (improves accuracy to ±0.3dB); ② Use calibrated waveguide adapters (provided with rental).
