With the Spectrum Analyzer mode the user is freed from the need to translate scope sample rate, memory, and acquisition length settings into frequency domain relevant units. Other settings for reference level and scale may also be made. Then, select an operational mode (Normal, Average, or Max Hold) for the spectrum display.

Settings for normal or averaged FFTs as well as reference levels and scales are also available. Setup is simple - select a center frequency, span, and resolution bandwidth and the necessary sample rate and time-domain acquisition length of the oscilloscope are automatically determined behind the scenes. It allows users who are familiar with RF spectrum analyzers to start using the FFT with little or no concern about the details of setting up an FFT. Now, a spectrum analyzer like capability is available to simplify setup and use of the oscilloscope for analyzing frequency-dependent effects. Fast Fourier Transforms (FFTs) have long been part of oscilloscope toolboxes. Spectrum Analyzer Mode in HDO Oscilloscopes Simplifies Frequency AnalysisĪn oscilloscope provides powerful capability to debug frequency-related effects.
