Abstract: A received signal is converted in a frequency converter, an output from which is again frequency converted. The second converted output is detected by a detector and then converted into a digital signal to be stored in a memory. A spectrum display is provided by a display. A frequency sweep of local signals supplied to frequency converter is enabled. While holding the frequency sweep for the earlier stage suspended to receive one of the radio waves in service, a signal to the input of the frequency converter may be branched and demodulated by demodulation means. A vertical sync signal is separated in monitor processing means and the frequency of the local signal generator may be swept only during a no-modulation interval contained in a vertical blanking interval, thus extracting a carrier component and a noise component, the levels of which are determined to provide a measure of C/N.
