    Noise generator Ya5Kh-272
    Also, this device can be called: Я5Х 272, Я5Х272, Я 5Х-272, Я-5Х-272, Я 5Х 272.
    Ya5Kh-272 noise generator  is intended for use as a calibrated noise signal source in the range of 25.86 GHz to 37.50 GHz.
    Noise generators consist of three main components: the power supply noise generator on a discharge lamp load agreed. Power supply is designed to supply voltage to the discharge lamp noise generator.
    Noise generator Ya5Kh-272 consists of a discharge lamp and fittings, in which he is placed. Armature generator Ya5Kh-272 contains a segment of the waveguide with a cross section of 7.2x3,4 mm, on which the lamp socket. The cartridge is installed so that light passes through the broad wall of the waveguide at an angle of approximately 7° relative to the main axis of the waveguide. This coordination is provided by the lamp to the waveguide over a broad frequency range.
