Noise generator Ya5Kh-269
Also, this device can be called: Ya5Kh 269, Ya5Kh269.
Ya5Kh-269 noise generator is intended for use as a calibrated noise signal source in the range from 3.2 GHz to 12.05 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-269 consists of a discharge lamp and fittings, in which he is placed. Armature generator YA5H-strip line 269 contains a special form, between the strip and the housing is installed discharge lamp. Choice forms the central strip ensures consistency discharge lamp in a wide range of frequencies.
