Abstract

We propose a verification device to validate the calibration of a nonlinear vector measurement instruments such as Nonlinear Vector Network Analyzer (NVNA). The verification device is a two-port device that has two operating modes, namely linear and nonlinear. The designed circuit’s response is almost insensitive to small harmonic mismatches of the instrument ports (|G| < 0:1). Since neither an amplifier nor a circulator is used, the traceability procedure of the device to Electro-Optical Sampling (EOS) is less complicated compared to earlier prototypes.
