A broadband noise-signal spectrometer of a millimeter wavelength band

详细

The spectrum recording method for the broadband noise signal of millimeter wavelength band is considered. It is based on using resonance frequency meters of the millimeter wavelength band, removing the part of the power from the base waveguide transmission line at the resonance. This frequency meter with a changed design makes it possible, together with a corresponding recording device, to unambiguously define the spectrum width of a broadband noise signal and make a paper copy. An example of spectrum recording on the S4-60 spectrum analyzer screen and a paper copy made by a two-coordinate self-recording instrument is presented.
