Abstract :
A spectrum analyzer is designed and constructed on the base of a direct conversion receiver. A millimeter-wave heterodyne receiver is applied to expand input frequency range of the spectrum analyzer. At present the spectrum analyzer operates at frequencies between 149 and 212 MHz, i.e. 64 channels with 1 MHz resolution.
