摘要： Analysis systems can include both a test and measurement tool for generating measurement data representative of at least one parameter of a device under test and an imaging tool for generating image data representative of a target scene. An electrical isolation mechanism can electrically isolate a user operating the analysis tool from the test and measurement circuit through the imaging tool. The electrical isolation mechanism can include an insulating coating surrounding a part of the imaging tool having an opening proximate the imaging tool so that electromagnetic radiation can enter through the opening and reach the imaging tool. The opening can be sized so that a standard finger cannot penetrate the opening to within a predetermined distance of the imaging tool. Additionally or alternatively, a window positioned over the opening can prevent access to the imaging tool via the opening.

摘要： A connector has a housing with an aperture formed therein having one portion larger than the other portion. The housing is mounted on the device under test with the housing positioned over a plurality of electrical contacts. An electrical load is positioned within the larger aperture of the housing and has a plurality of resistors disposed adjacent to an electrical contact assembly. A resilient member is positioned between the electrical load and the device under test such that a force directed on the electrical load compresses the resilient member to allow contact between a plurality of electrical contacts of the electrical contact assembly and the plurality of the electrical contacts on the device under test. Removing the force decompresses the resilient member and disconnects the plurality of contacts of the electrical contact assembly from the plurality of electrical contacts of the device under test.

摘要： Embodiments of the present invention provide an improved cable assembly for connecting an electrical test and measurement probe to a device under test. One end of the probe is connected to a device under test ("DUT"), while the other end is connected to the instrument through one or more cables. To prevent mechanical stresses to the probe-DUT interface caused by the cables' resistance to bending and twisting, embodiments of the improved cable assembly use one or more pliable spines to hold the cable assembly in position after it has been bent or twisted. This provides a more secure connection to the DUT and prevents damage to the probe-DUT interface. Each spine is anchored to the tip of the probe, and may be further secured by an outer housing or additional anchors. A flexible boot may surround the cable assembly and/or outer housing, further protecting the cables from damage. Alternatively, one or more spines may be placed inside the boot.

摘要： A video noise analyzer for detecting residual point noise in a video generates a list of candidate defective pixels by joining results of a temporal invariance detector and a spatial outlier detector. A data store is structured to contain data describing the candidate defective pixels and/or the blocks from which the pixels were selected. In other embodiments, a video noise analyzer includes a first salient analyzer structured to compare pixels within a block to a mean value of other pixels within the same block, a first threshold processor to generate a first pixel candidate list including pixels that differ significantly from their neighboring pixels, a second salient analyzer structured to generate a difference value between a subject pixel, its neighboring pixels, and neighbors of the neighboring pixels, and an identifier to label as a candidate dead pixel those pixels having a frequency occurrence of visual saliency greater than a predefined frequency threshold.

摘要： A system for dynamically calibrating operational parameters of a Device Under Test (DUT) includes a signal generator for generating a data pattern, a DUT structured to generate a clock signal, an oscilloscope structured to measure margins of the generated clock signal compared to an eye-diagram produced on the oscilloscope from the data pattern, and a calibration unit. The calibration unit can produce a candidate jitter value for the signal generator, receive a determination from the oscilloscope whether the data pattern generated with the candidate jitter value causes the DUT to produce the generated clock signal within a pre-determined tolerance level, and modify the jitter value accordingly. The calibration unit may also be further structured to generate voltage swing values.

摘要： Embodiments of the present invention provide improved techniques for recovering clock information from data signals. In one embodiment, a general purpose device such as a real-time oscilloscope acquires a data signal. The device takes a derivative of the data signal, then computes the square or absolute of the derivative before applying a bandpass filter. The bandpass filter is a windowing function with a spectrum that is wider than the clock, and has a flat top and smooth transitions on both sides. In one embodiment, at Tukey window may be used. The device finds edge crossing times of the filtered result, and applies a phase-locked loop or lowpass filter to the edge crossing times in order to recover a stable clock signal. When the improved techniques are implemented in software, they may be used with any number of different equalizers that are required by various high-speed serial data link systems.
