摘要： Method and modular system for generating, capturing and re-displaying SDI video signals. When generating a video signal, data blocks are arranged in a line parameter memory, each corresponding to a complete video line and containing pointers to specific entries for lines of the video signal in a primary image memory holding a main bit-mapped image, and a video line construct memory holding data enable and blanking patterns before being serialized into a output data stream. On the capture side, a de-serializer/equalizer accepts an input data stream extracts Y (luminance), CB (blue-difference chroma) and CR (red-difference chroma) data along with clock/sync information which can be used for re-display. Optional support of HDMI, DVI and analog formats, such as composite video, raster video and stroke video, allows a single instrument to generate, acquire and process virtually all known video interfaces, using standard or custom image/formats.

摘要： A mixed signal testing system capable of testing differently configured units under test (UUT) includes a controller, a test station and an interface system that support multiple UUTs. The test station includes independent sets of channels configured to send signals to and receive signals from each UUT being tested and signal processing subsystems that direct stimulus signals to a respective set of channels and receive signals in response thereto. The signal processing subsystems enable simultaneous and independent directing of stimulus signals through the sets of channels to each UUT and reception of signals from each UUT in response to the stimulus signals. Received signals responsive to stimulus signals provided to a fully functional UUT (with and without induced faults) are used to assess presence or absence of faults in the UUT being tested which may be determined to include one or more faults or be fault-free, i.e., fully functional.

摘要： Method for generating a model of the effect of phase noise during use of a Doppler radar system including calculating, using a processor, an initial signal-to-clutter ratio (SCR) representing a ratio of power received from echoes from a target by the radar system to power resulting from clutter reflection received by the radar system. The initially calculated SCR is modified as a function of a range ambiguity and range resolution. A Doppler frequency of interest is calculated based on velocity of a target, target heading and radar frequency, along with a Doppler filter bandwidth, frequency components and a measure of clutter signal passing through the Doppler filter of interest by summing products of the phase noise for each frequency by the Doppler filter bandwidth. This measure indicates effectiveness of target detection by the Doppler radar system as a function of distance.

摘要： Method and system for testing any type of video display, video monitor or other device that produces a video signal, and that is capable of providing information about the video and optionally audio specifications and/or capabilities of the output signal to an external device when coupled thereto. The external device obtains the information about the specifications and/or capabilities and based thereon, assembles one or more pre-defined tests from a test database/repository containing tests to enable testing of compliance of the video signal producing device to those specifications and/or capabilities. This compliance testing may entail generating video or audio content at a source generator, providing it to the video signal producing device, and determining the accuracy of the output of the video signal producing device to the input content. A determination of the results of this test may be provided to an operator of the testing apparatus.
