Millimeter-Wave Measurement Instruments and Waveguide Components

Calorimetric Power Meter

Calorimeter Sensor Calorimeter Indicator Unit

The M1-25M/XXE 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 (measurement and indicator block), which provides PC connection via USB 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.
