ABSTRACT:
A spectrum analyzer for analyzing an input spectrum. The analyzer includes a down converter capable of converting blocks or portions of the input spectrum to a corresponding predetermined output band of frequencies. A stepping device associated with the down converter sequentially selects portions of the input spectrum for conversion by the down converter. An A/D converter converts the output of the block converter into digital signals. A digital filter selects a predetermined frequency band from the predetermined output band of frequencies of the block converter. A processing unit effects FFT operation on data contained within the predetermined frequency band. A memory device sequentially stores the output from the processing unit.
