| Zusammenfassung: | The frequency spectrum measuring system includes successively connected one pre-amplifier for receiving and amplifying input radio signal; one frequency demultiplier for reducing the frequency of the amplified signal to form IF signal; one IF filter for filtering the IF signal in set frequency resolution and IF frequency; one power meter for measuring the power of the IF signal; and one PC for reading the power data the power meter measures, converting the read frequency into practical frequency based on set frequency spectrum signal correcting list, and drawing the frequency spectrum analysis diagram of power vs frequency. |
