摘要： Method for processing eye diagram data from a system under test includes mapping channels of a logic analyzer for eye diagram data signal acquisition to DSO inputs, acquiring signals from the channels, determining if there are additional channels for signal acquisition and in response to the completion of acquisition signals, automatically mapping the additional channels to the DSO inputs and acquiring data signals from the additional channels. The steps are repeated until all selected channels are analyzed. An apparatus includes means for selecting a first plurality of channels for eye diagram signal acquisition and mapping the first plurality of channels to DSO inputs, means for acquiring a first plurality of signals from the first plurality of channels, means for sending a completion of acquisition signal and means for automatically mapping a second plurality of channels for eye diagram signal acquisition to the DSO inputs in response to the completion of acquisition signal. The DSO then sends the eye diagram data to the Logic Analyzer for display.

摘要： A position sensor monitors relatively fast moving objects with signal conditioning for reduced power and reduced wiring. A transducer and related circuitry generate a dynamic signal proportional to a position of a moving object and also generate one or more low frequency or static (DC or zero frequency) error signals. The low or zero frequency error signals are removed and a position signal is generated using only two connections to a remote sensor monitor, thus allowing ease in multiplexing and reduced wiring.

摘要： A method and apparatus for analyzing jitter in a signal. The signal is buffered to form a sequence of signal vectors and a time interval error function is calculated for each the signal vector. A time interval error spectrum is then calculated by transforming the time interval error function using a discrete Fourier transform. An average time interval error spectrum and an average power spectral density function are then calculated as averages of the amplitude of the time interval error spectrum and its amplitude squared, respectively. Parameters of the signal jitter are estimated from the average time interval error spectrum and the average power spectral density function.

摘要： Disclosed are a method and system for processing timing information with respect to an electronic device. The method comprises the steps of generating a first set of responses from the device at a first frequency in response to a first timing signal, and generating a second set of responses from the device at a second frequency in response to a second timing signal. The method comprises the further steps of receiving the first and second sets of responses from the device, and processing the received responses to identify responses that are in synchronization with the first timing signal and responses that are in synchronization with the second timing signal. These timing signals may be related to clock signals applied to the electrical device, to clock signals internally generated by the device, or to extraneous noise that affects the electrical device in some fashion.

摘要： The present invention relates to a method for measuring jitter tolerance for diagnosis by instructing a jitter adding circuit disposed precedingly to an intended circuit block to generate jitter with a desired magnitude, monitoring at least one output signal outputted from an LSI to be evaluated for judging on whether or not the characteristic of this output signal satisfies a desired standard. It also relates to a jitter tolerance diagnostic apparatus to which this method is applied. According to the jitter tolerance diagnostic method and apparatus of the present invention, with a simple interface provided, it is possible to measure jitter tolerance of the entire LSI to be evaluated and of an intended circuit block therein.

摘要： An instrument includes a probe providing a single signal path for conveying a signal from a circuit under test to the instrument. A receiver circuit within the instrument divides the path into an analog path and a digital path. The digital path includes a comparator for determining the logic state of the signal and producing a digital representation of the signal under test. The analog path includes a multiplexer to selectively couple one of a plurality of analog input signals to an output terminal for viewing on an oscilloscope. Preferably, the probe head includes a buffer amplifier to reduce loading on the circuit under test and to increase bandwidth of the signals conveyed along the test cable to the instrument. An electrically trimmable resistor is employed to terminate the transmission line of the test cable in its characteristic impedance in order to reduce reflections and maintain transmission bandwidth.

摘要： A handheld computer unit for use by, e.g., a car sales person (seller) prompts the seller with a standard script to be followed at each step in the process after a prospect enters a dealership. The prospect's response to the scripted questions is used to identify the prospect's particular interests of a general nature, e.g., safety, and of a specific nature, e.g., trailer towing capacity. When either a general or specific interest is identified, the seller is prompted to tailor the conversation to address the prospect's interests. Among other things, the handheld unit can perform functions such as (i) permitting the seller to retrieve useful information such as inventory availability from a sales information data store; (ii) displaying option-sensitive prompts to aid the seller in discussing specific vehicles under consideration; (iii) accessing remote communications links to external data sources to obtain information on credit-worthiness of the prospect, financing terms, and availability; (iv) displaying motivational information such as the percentage likelihood of consummating the sale successfully; (v) providing a communications link with management personnel.
