<strong>Measurement</strong> with NRL Arch andoption 200 of 85071EA typical reflectivity measurement with PNA network analyzer, 85071Esoftware with option 200 and NRL arch. For this measurement (option 200)a PNA or 8510 network analyzer with time domain option is required. Themeasurement shows distinct minimum of reflectivity for lower frequencies.76
Transmission Free-Space Technique SummaryFrequency Range: Banded 5 to 325GHzInstrument: Network AnalyzerAccuracy: typically ±2-5% for ε r’ and ± 10 -2 for tanδNon-Contacting!Sample must be flat and uniformthickness. Thickness must beknown.Best for flat sheet and othermaterials that can be shaped.Needs large samples for lowfrequenciesWorks for magnetic materials77
