Abstract: R.F. characterization of C-band dual mode ferrite phase shifter cannot be done manually due to enormous and huge amount of data. So this paper provides the solution in term of automated procedure for testing of C-band DMPS in LabVIEW(Laboratory Virtual Instrument Engineering Workbench) software. Dual mode phase shifter is currently being used in phased array Radar and WLR (Weapon Locating Radar). The DMPS is in production to realize the exorbitant demand of these radars. The desirable characteristic of phase shifter for phased array radar as differential phase shift, insertion loss, return loss, Hi-low phase difference, insertion phase, Rx-Tx phase can be measured with high accuracy. The output can be presented in any desirable form such as concluded summary form, graphical form and in excel sheet for future reference purposes.
