   Noise generator Ya5Kh-270
    Also, this device can be called: Ya5Kh 270 Ya5Kh270, Ya 5Kh-270, Ya-5Kh-270, Ya 5Kh 270.
 
    Ya5Kh-270 noise generator is intended for use as a calibrated noise signal source in the range of 12.05 GHz to 17.44 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 GSH. With the help of gas discharge lamp can be operated in two modes: a) continuous combustion mode, and b) the modulated mode.
    Noise generator Ya5Kh-270 consists of a discharge lamp and fittings, in which he is placed. Armature generator Ya5Kh-270 contains a segment of the waveguide with a cross section 19h8 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.
