Automated Measurements Full Waveguide Frequency Band
The CPMXXE series instruments are high precision broadband Calorimetric Sensors operating in millimeter and sub-millimeter wave range on a principle of substitution of microwave power by direct current power, using an autocompensating transistor transducer. Calorimetric Sensor is supplied with Calorimetric Power Meter M1-25M (indicator block), which provides PC connection via RS-232 interface.
Calorimetric Power Meter with Calorimetric Sensor provides accurate absolute power measurements in single mode and multimode waveguides (Metal Dielectric Waveguide) which could be a priority for terahertz physics and technology.
