Abstract: A test and measurement instrument includes an input port for accepting an input signal for measurement, a display having a first window for showing measurements of the input signal in a time domain, and having a second window for showing measurements of the input signal in a frequency domain, where the time domain of the first window and the frequency domain of the second window are related through a transform having a pre-determined resolution bandwidth, a cursor generator structured to generate a cursor at a specific location in time in the first window, a spectral generator to produce a spectral display of a portion of the input signal that is centered around the cursor and has the pre-determined resolution bandwidth, and an image generator configured to present the generated spectral display in the second window. Methods of generating spectral displays based on user-defined cursor locations are also described.

Abstract: A test and measurement instrument includes a spectrogram generator for producing a first spectrogram image from an input signal, a display for showing the spectrogram image, and a user interface operating in conjunction with the display, the user interface including one or more user controllable inputs and the user interface configured to detect a user action, where the spectrogram generator is structured to produce a second spectrogram image, different from the first spectrogram image, based on the detected user action by the user interface. Methods of automatically generating spectrograms based on user actions are also described.
