Noise generator Ya5Kh-271
Also, this device can be called: Ya5Kh 271, Ya5Kh271, Ya 5Kh-271, Ya-5Kh-271, Ya 5Kh 271.
Ya5Kh-271 noise generator is intended for use as a calibrated noise signal source in the range of17.44 GHz to 25.86 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-271 consists of a discharge lamp and fittings, in which he is placed. Armature generator YA5H-271 contains a segment of the waveguide on which the lamp socket. The cartridge is mounted so that the light passes through the broad wall of the waveguide at an angle of approximately 7° relative to the main axis of the waveguide. This ensures consistency of a discharge lamp in a wide range of frequencies.
