Automated field uniformity measurements to meet requirements of IEC 61000-4-3

As per international regulatory bodies on electromagnetic compatibility (EMC) every electrical / electronic product need to be tested for electromagnetic compliance. There are several emission / immunity standards set up to meet these requirements. Among IEC61000-4-3 is a EMC standard which looks after the radiated immunity (RI) compliance. This standard specifies the calibration / test procedures for RI test, the test procedures mentioned in this standard cannot be executed perfectly by a test engineer manually since the standard specifies the dwell time to be maintained during the test for each and every spot frequency. Hence there arises the need to have an automated setup for radiated immunity test as per IEC61000-4-3.
