Abstract: | A method of checking a broadband self-compensation power converter for the 118–180 GHz frequency band in an isothermal microcalorimeter with a cooling thermoelectric element is considered. The results of a comparison of the check in a microcalorimeter with that of the State Standard of the unit of power are presented. It is concluded that it is possible to reduce the uneliminated systematic error of highly accurate methods of measuring power.Translated from Izmeritel'naya Tekhnika, No. 2, pp. 43–45, February, 1994. |
