Automatic Calorimeter System for the Effective Efficiency Measurement of a Bolometer Mount in 35-GHz Band

An automated calorimetric measurement system using a microcomputer has been developed for determining the effective efficiency of a bolometer mount in the millimeter-wave region. This system consists of a calorimetric measurement part, a bolometric measurement part, and a control/data processing part. The system has been constructed and experimented in 35-GHz band. The accuracy of the system has been estimated within ±0.37 percent.
