    摘要: A test and measurement instrument includes a display having a time domain graticule and a frequency domain graticule. A processor is configured to process an input signal to generate a time domain waveform for display in the time domain graticule, the input signal being correlated to a time base. The processor is also configured to process a second input signal and generate a frequency domain waveform for display in the frequency domain graticule, the second input signal being correlated to the same time base. The frequency domain waveform is correlated to a selected time period of the time base. The processor is also configured to generate a spectrum time indicator configured to graphically illustrate a transform parameter, a location and the selected time period in the time domain graticule with respect to the frequency domain waveform.

The test and measurement instrument can include, for example, one or more input terminals to receive an electrical signal under test, an analog-to-digital converter (ADC) to digitize the signal under test, a digital downconverter to produce I (in-phase) and Q (quadrature) baseband component information from the digitized signal, a memory configured to store the IQ baseband component information, a user interface, and a controller. The controller can be configured to generate an IQ-based time domain waveform using the IQ baseband component information, and present the IQ-based time domain waveform and a second time domain waveform on a common axis through the user interface.

    摘要: Disclosed is a test and measurement instrument that includes a signal input structured to receive a modulated radio frequency (RF) signal under test and a demodulator structured to extract a digital signal from the received modulated RF signal. The extracted digital signal has a measurable parameter. The instrument also includes a display controller structured to display the extracted demodulated signal at one of at least two different intensities based on the measured parameter of the digital signal. In other embodiments the signal need not be an RF signal. Methods of operation are also described.

    摘要: A method of grouping multiple waveforms for a single channel of acquired data on a display area uses a graphic icon with the display area. The graphic icon has a first portion with a symbol indicating the single channel and with an indicator defining a baseline for the display area. The graphic icon also has a second portion with symbols indicating which of the multiple waveforms currently are being displayed. The symbol for the single channel and the symbol for a selected one of the multiple waveforms currently being displayed are highlighted. The highlighting may be via color, where the highlight color corresponds to the color of the waveforms currently being displayed.

    摘要: A user interface for an oscilloscope, or the like, simultaneously displays data in a plurality of selectable formats, such as hexadecimal or binary, and allows a user to edit the data in a selected one of the formats. The data is input by an operator of the oscilloscope and used to trigger the oscilloscope or is used as a search term for searching a received oscilloscope data record for an occurrence of that data. The content of the operator-entered data may be text or numeric data or it may be representative of a memory address. The individual digits of the data or whole blocks of data may be selected for entry or editing.
