Abstract: A test and measurement instrument, comprising a display and one or more processors configured to display a waveform viewing area, receive a selection of a viewing mode. When an overlay viewing mode is selected, display two or more waveforms overlaid in a single graticule in the waveform viewing area, and when a stacked viewing mode is selected, display a first waveform in a first slice having a first graticule in the waveform viewing area and display a second waveform in a second slice having a second graticule below the first slice in the waveform viewing area.

Abstract: A test and measurement instrument and method are disclosed. The test and measurement instrument includes a display having a time domain graticule and a frequency domain graticule. A processor is configured to sample an input signal to generate a time domain waveform for display in the time domain graticule. The processor is also configured to generate a frequency domain waveform for display in the frequency domain graticule, the frequency domain waveform being correlated to a selected time period of the time domain graticule. The processor is also configured to generate a spectrum time indicator configured to graphically illustrate a location and the selected time period of the time domain graticule with respect to the frequency domain waveform.

Abstract: A test and measurement instrument including a digital down converter configured to receive a bus signal and output in-phase and quadrature-phase baseband component waveform data, a trace generator configured to receive the in-phase and quadrature-phase baseband component waveform data and generate at least one radio frequency versus time trace, a decoder configured to receive the at least one radio frequency versus time trace and decode the bus signal based on the at least one radio frequency versus time trace and a wireless modulation scheme, and a trigger configured to capture at least a portion of the bus signal based on the decoded bus signal.

Abstract: Embodiments of the invention include methods and instruments for performing combinatorial mask triggering. One or more mask triggers can be configured. Combinatorial mask triggering logic can make various determinations about the relationship between a digitized signal and the one or more mask triggers. The various determinations about the relationship can include considerations of both space and time. When the combinatorial trigger criteria have been satisfied, a trigger signal is generated, and the digital data associated with an incoming signal is stored to memory. The combinatorial mask triggering logic can operate on signals in the frequency domain, the time domain, or both.

Abstract: A test and measurement instrument includes a first channel input for accepting a first input signal, a second channel input for accepting a second input signal, a spectrogram processor for producing a first spectrogram from the first input signal and for producing a second spectrogram from the second input signal, and a display for simultaneously showing the first spectrogram and the second spectrogram. Methods are also described.

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.
