Abstract: A test and measurement instrument converts digital data that represents an input signal into a plurality of bitmaps, and then subtracts one of the bitmaps from another one of the bitmaps to produce a difference bitmap. The difference bitmap does not contain density values that are common to the two bitmaps, but instead only contains the density differences between the two, thereby revealing very small density variations in the presence of large density values. In some embodiments, the difference bitmap is displayed on a display device. In other embodiments, the difference bitmap is used to generate a trigger signal.

Abstract: Measuring wireless network performance from a remote site uses a mobile handset that may include an appropriate world wide network browser. A user connects the mobile handset to the remote site via the wireless network which is coupled to the world wide network. Once the connection is made, application software at the measurement site sends commands to the mobile handset and in response the mobile handset sends measurement data to the application software. The application software processes the data to provide information about the wireless network performance including analyses for predictive and diagnostic purposes, since measurement data from many handsets, many locations and many base stations at many times may be collected at one central location.

Abstract: A test and measurement instrument processes digital data that represents an input signal to produce a target image, and then uses a computer vision technique to recognize a signal depicted within the target image. In some embodiments, the location of the signal within the target image is identified on a display device. In other embodiments, the location of the signal within the target image is used to perform a measurement. In other embodiments, when the signal is recognized, a trigger signal is generated that causes digital data that represents the input signal to be stored in a memory.

Abstract: A “density trace” according to an embodiment of the present invention is formed by measuring the density of each column of a frequency domain bitmap above a user-specified “amplitude threshold.” The density of each column equals the sum of the densities of all of the pixels in the column that are above the amplitude threshold divided by the sum of the densities of all of the pixels in the column. A density trace provides a convenient way to define and represent the occupancy for a large number of columns, and also allows density data to be quickly transmitted from one instrument or computer to another. In some embodiments, a density trace is incorporated into a trigger detector of a test and measurement instrument and used to generate a trigger signal. The trigger detector compares the density trace to a user-specified “density threshold” and generates the trigger signal when the value of any point of the density trace violates the density threshold.

Abstract: An RF test and measurement device, including a front end for receiving a time-varying signal and a real-time engine for generating digital frequency domain spectrums based on the time-varying signal. The device also includes a memory subsystem containing a frequency domain bitmap which is updated through sequential receipt and storage of the digital frequency domain spectrums. The real time engine is further configured to monitor the frequency domain bitmap for occurrence of a signal characteristic, and in response to detection of the signal characteristic, cause a capture of the time-varying signal into a storage location of the RF test and measurement device.

Abstract: A system for providing an easily usable composite legality and component gamut display translates a video input signal into a plurality of component and composite format signals. A user selects from the plurality of component and composite format signals a pair of signals for input to the y-axis and x-axis of a rectangular plot. The resulting rectangular plot includes every pixel within a video frame of the video input signal and, together with prescribed limits, is displayed to provide a visual indication of composite legality and/or component gamut.

Abstract: A test and measurement instrument includes an input for receiving an input test signal and a separator that separates a data array of the input test signal into a number of different data bins. Each data bin includes a number of data points. A selector is included that determines whether the data points within a present bin of the total bins represent signal or noise. When the present bin contains noise, a processor generates a first output for the present bin. Instead, when the present bin contains signal, the processor generates a second output for the present bin. The bin outputs can then be combined to make an output array, such as a waveform display, for the instrument.

Abstract: A display of code power levels and relationships of multiple spreading factor orthogonal codes in a code division multiple access (CDMA) signal has a first code graph of code domain power (CDP) for all the codes at the largest code spreading factor that includes all codes at all spreading factors plotted in a linear code indexing order and a second graph of CDP where the codes are plotted in bit-reversed order to group together the sub-codes of each code of lower spreading factor. Markers on each graph are tied together such that movement of one marker on one graph to a particular code value causes the other marker on the other graph to move to the corresponding code value. The sub-codes related to a particular code bar in the graphs indicated by the markers may be differentiated by using grey scale or color variations. A base code power level indicator, which may be in the form of a horizontal bar on the bit-reversed order graph spanning the group of sub-codes corresponding to a particular spreading factor, provides a power indication for the base code.
