Such spectra have been obtained in the widefrequency range between 10MHz and 43.5 GHz, simultaneously covering both the low-frequencynoise and the fundamental oscillation peak at some tens of GHz. This provides valuable informationto better understand how these fluctuations appear and how these are distributed in frequency.For much higher frequency operation, such understanding can be utilized as a simple tool to predictthe presence of Gunn oscillations without requiring a direct detection.
