The EMI measurement system consists of an Electro-Metrics Model EMC-30 Mark IV precision RF selective voltmeter and Yokogawa DL1540 digital oscilloscope configured as a calibrated spectrum analyzer. The system is interfaced with a notebook computer via an IEEE 488 General Purpose Interface Bus. All measurements are traceable to the National Institute of Standards and Technology to conform to applicable ANSI and IEEE Standards and the International Electrotechnical Commission’s Special Committee on Radio Interference (CISPR).
