For years, when discussing high field-strength electromagnetic compatibility (EMC) radiated susceptibility testing, Traveling Wave Tube Amplifier (TWTA) technology has been the only available option for pulsed field generation. Now, there is a very attractive alternative to this technology.

An efficient computational design optimization method, combining full-wave electromagnetic simulation in COMSOL Multiphysics® software with a space-mapping (SM) algorithm implemented in MATLAB® software. 

VNAs make measurements in the frequency domain and can be used to supplant the information that native time domain instruments, like fast oscilloscopes, Signal Quality Analyzers (BERTs) and Time Domain Reflectometers/Transmission instruments (TDR/TDT’s) already provide.
