Automatic Test Procedure for RF Characterization of C-band Rotary Field Phase Shifter

This article presents the concept and methodology for the realization of an automatic test procedure based on LabVIEW for RF characterisation of a C-band rotary field phase shifter. Using this software, all the characteristics of a phase shifter intended for phased array application, such as differential phase shift, insertion loss, return loss, rms phase error, insertion phase etc, are measured and displayed graphically.
