  • Abstract
    At present, thermoelectric technique is a popular method to setup national RF power standards. From the measurement, the Lab´s temperature stability has strong affected the thermopile´s output voltage. In this paper, the reason of the influence to calorimeter´s measurement from Lab´s temperature change is analyzed. We use the Average Temperature Block (ATB) to eliminate the affection. The measurement results of before and after ATB used is presented.
