This paper investigates practical aspects of measuring antennas operating with pulsed RF signals of very narrow width, down to 0.1 µs or less. The current generation of network analyzers provides very high IFBW, theoretically allowing measurement of very narrow A simple diode-based nonlinear verification device (NVD) design for nonlinear vector network analyzers is presented together with an improved figure of merit (FOM) parameter that is insensitive to impedance match and isolates variation of the devicequoteright s
