Description

technical field

[0001] The invention relates to a control and acquisition device, in particular to a control and acquisition device for a microwave power calorimeter. Background technique

[0002] Microwave power is one of the most basic parameters in the microwave field. When establishing microwave low power standards, the calorimeter method is often used. The microwave power calorimeter is an instrument that measures the temperature change after the load absorbs power, and obtains the value of the measured microwave power according to the temperature change caused by the DC power and the microwave power. The advantages of microwave power calorimeter are high measurement accuracy, strong overload capacity, large dynamic range, and good impedance matching; the disadvantages are complex structure, large time constant, long measurement time, and high requirements for the stability of ambient temperature and supporting measurement equipment. .

[0003] Due to the complex stru...
