| Popis: | UDC 535.8:535.124.4 A radiometer is described in which the mean power of the reference signal is controlled by varying the open state duration of the pin modulator at constant effective temperature of the reference noise generator. The method ensures an almost linear calibration curve over a wide range of temperatures. Test results of the radiometer are reported. |
