The automatized measuring system (AMS) designed by State Research Institute on Radar Systems "Kvant-Radiolokatsiya" is described in this report. It allows with high accuracy to perform automatic adjustment and selection of code combinations, which provide the optimal control of multi-bit phase shifters in phased array antenna (PAA) that ensure the minimal phase error and practically constant insertion loss at all working frequencies. Special attention is devoted to problems of the reduction of measurement errors, calibration procedures, time costs reduction and increasing productivity.
