Abstract: Methods and systems are provided for determining the surface electromagnetic impedance of a conductive element and applying the diffuse field reciprocity principle using that surface electromagnetic impedance to determine electric fields induced in the conductive element. An exemplary method involves determining a surface electromagnetic impedance matrix for the conductive element based on its physical dimensions and an excitation frequency for an incident electromagnetic wavefield, applying diffuse field reciprocity to determine a metric indicative of an induced field based on the surface electromagnetic impedance matrix and an energy metric for the incident electromagnetic wavefield, and displaying a graphical representation of the metric on a display device.

Abstract: A system and method for calibrating oscillograph channels assigns the same value to a drawing parameter of each channel. Each channel receives a signal sent by a signal generator. The oscillograph calculates a voltage difference between a standard signal voltage of a standard channel defined by a user and a signal voltage of each of the other channels. A sequence relationship between each of the other channels and the standard channel is determined. The oscillograph adjusts a deskew value of each of the other channels until each voltage difference is in an allowable range according to the sequence relationship.

Abstract: A simple, integrated control for pan and zoom of a display of data represented by a very long data record is in the form of a control knob having an outer ring for controlling pan and an inner knob for controlling a zoom factor. A zoom function is turned ON either by turning the inner knob (setting the zoom factor to a default value) or by (i) pressing an adjacent zoom or pan button or (ii) turning the outer ring (setting the zoom factor to a prior value when the zoom function was turned OFF). The zoom function may be turned OFF by turning the inner knob to set the zoom factor to 1× or by pressing the zoom button. The outer ring has individual positions divided into two groups: one group for controlling pan rate within a zoom window displaying a portion of the very long data record defined by a zoom box within a main window displaying the very long data record; and the other group for controlling pan rate of the zoom box within the main window for rapid movement from one end of the record to another.

Abstract: A method for determining the frequency distribution of the signal level of a measured signal measured respectively in overlapping observation intervals via a time or frequency raster. The method includes determining the incrementation of a memory cell in a first memory to be implemented for each measured signal level of the measured signal at a value of the time or frequency raster, and un-delayed summation of the incrementation determined for every memory cell of the first memory in every measurement cycle. The method also includes delayed summation of the incrementation determined for every memory cell of the first memory in every measurement cycle, and subtracting the result of the delayed summation of the incrementation determined for every memory cell of the first memory in every measurement cycle from the result of the un-delayed summation of the incrementation determined for every memory cell of the first memory in every measurement cycle.

Abstract: A method for improving bandwidth of an oscilloscope involves, in preferred embodiments, the use of frequency up-conversion and down-conversion techniques. In an illustrative embodiment the technique involves separating an input signal into a high frequency content and a low frequency content, down-converting the high frequency content in the analog domain so that it may be processed by the oscilloscope's analog front end, digitizing the low frequency content and the down-converted high frequency content, and forming a digital representation of the received analog signal from the digitized low frequency content and high frequency content.

Abstract: A logic analyzer that performs analog-type measurements on digital data includes circuitry in its acquisition system that is programmable to search through acquired data to detect analog-type signal characteristics. In a first embodiment, the logic analyzer includes a graphical user interface employing a drag-and-drop operation to apply one or more selected analog-type measurements to selected portions of the digital data record. In a second embodiment, a user may designate a particular waveform or data listing by means of a mouse-click. Each of the choices of analog-type measurements can be represented by an icon, or text, or both icon and text. Some of the analog-type measurements, among others, are pulse width, duty cycle, period, frequency, period jitter, and cycle-to-cycle jitter
