This paper presents some theoretical considerations on the effect of using heater wires whose length is comparable with the wavelength of the radiation, and describes methods of using them to measure the output of local oscillators and of signal generators at Wavelengths of 10 and 3 cm. The theoretical treatment is limited to the case of very small power inputs (< 10¿4 watt) where the differential equations involved have simple solutions. Its interest lies chiefly in the use of lamps for the calibration of signal generators and the measurement of noise factor of a receiver.
