<strong>Measurement</strong> Techniques that use a VectorNetwork Analyzer• Transmission Line and Free-space• Coaxial Probe• Resonant CavityAt the higher frequencies, a network analyzer is used. The next threetechniques we will discuss use a vector network analyzer.32
Transmission Line SystemComputer(not required for PNA)Network AnalyzerGPIB or LAN8507IE SoftwareSample holderconnected between coax cablesA typical transmission line system consists of a vector network analyzer anda sample holder connected between the two network analyzer ports..Software calculates permittivity from calibrated full 2 port S-parametermeasurements. Agilent offers this software and several varieties oftransmission line sample holders. .33
