摘要： A mixed-domain oscilloscope (MDO) includes a signal generator configured to generate a test signal having a span ranging from a user-configurable start frequency to a user configurable stop frequency, an output channel coupled to the signal generator and configured to transmit the test signal, an RF input channel configured to receive a return signal based on the test signal, an acquisition section configured to acquire and digitize the return signal as an acquisition record, and a ramp busy signal generator configured to substantially time-align the acquisition record with the test signal. The test signal includes a chirp signal that is a linearly swept sine wave that spans between the user-configurable start frequency and the user-configurable stop frequency. Methods include calibrating the chirp signal, connecting the MDO in various test configurations relative to external return loss bridge and DUT equipment, and performing measurements such as S21(db), S11(db), and distance-to-fault type measurements.

摘要： A method of analysis of long record length data using mark duration includes displaying together with a portion of the long record length data each mark that identifies a specified feature of interest together with the mark duration. Associated with the mark may be text identifying the feature of interest, measurement values associated with the duration of the mark, or a combination thereof. Multiple sets of marks may be generated for the long record length data, which sets may be combined to generate new marks with duration. The marks also may be filtered to further refine the marks to be displayed according to user specified criteria. In this way analysis of long record length data representing an acquired signal may be readily automated so a user may move from one interesting event to another without having to pan through the long record length data.

摘要： A test and measurement instrument acquires a signal from a device under test, displays that signal as a source waveform, and makes measurements on that source waveform with regard to a predetermined property or event. The test and measurement instrument employs the method of the subject invention for placing these measurements into a waveform and directly correlating a position in the measurement waveform to the same area on the source waveform where they were measured. Specifically, the subject invention displays the correlation of points on a source waveform and a measurement waveform without requiring the use of a common horizontal time scale. In one embodiment of the invention, the measurement waveform is a histogram and a pointer to a given location in the histogram causes identification of corresponding areas in the source waveform.

摘要： A multifunction testing and measuring device having a probe body with an elongated portion extending outward from a rearward main body portion to a hook-shaped forward end, the hook-shaped end useful for isolating a conductor under test, a slide closure member adapted to slide longitudinally forward from a rearward open position to a forward closed position, the closed position useful to capture the conductor under test within a space encircled by the combination of the hook-shaped end, the closed slide closure member, and the rearward main body, with the space encircled including a current sensing zone, and having test leads integral to and stowable on the main body. The multi tester comprises circuitry adapted for detecting a magnetic flux generated by an electric current passing through the conductor under test positioned within the current sensing zone, for sensing current and inrush current, as well as selectably measuring voltage, continuity, and resistance between the test leads.

摘要： A method for operating a data processing system having a touch enabled display screen that displays a plurality of waveforms to alter the display of one of the waveforms without altering the display of the remaining waveforms is disclosed. The method includes determining a selected waveform in response to a user touching the display screen in a first location thereby defining a touch area that determines the selected waveform. An operation that is to be performed on the selected waveform is then defined by a gesture on the screen. The selected waveform is determined by a touch area that is defined by the user touching the screen. If more than one waveform is defined by the touch area, the possible waveforms are sequentially selected until the correct one is presented to the user in response to the user repeating the touching that defines the touch area.
