英文摘要：

According to the requirements of electromagnetic compatibility （EMC） standards for the operation condition of equipment under test, two kinds of novel auxiliary equipment, low noise recorder of the information of the operation condition of equipment and integrated EMC electrical parameter test equipment, were introduced. The design principle of the equipment for monitoring and controlling the operation condition were introduced in detail. Since the background noise level is lower enough, the measurement circumstance satisfies the requirement of EMC standards. Application of the new instruments for EMC measurement was analyzed in detail. The results demonstrate that it can be utilized in the measurement of the conducted emission, the disturbed power and harmonic current emission.
