摘要:
A method calibrates a second oscilloscope according to setting values of a first oscilloscope. The setting value of the first oscilloscope is stored into a first file which is readable by any oscilloscope, and also into a second file. Test data obtained from testing an electronic signal using the first oscilloscope is stored into a third file, and waveform data obtained from testing the electronic signal are stored into a fourth file. The second oscilloscope acquires the first file, the second file, the third file, and the fourth file to reset the setting value of the second oscilloscope to the same as the setting value of the first value, for reproducing the test data of the third file and the waveform data of the fourth file.

A clamp apparatus includes a mounting base, a rotation actuator mounted to the mounting base, a beveled active gear driven by the rotation actuator, and at least two clamp jaws rotatably connected to the mounting base. Each clamp jaw includes a beveled driven gear engaging the beveled active gear of the clamp apparatus and a clamp body connected to the beveled driven gear. When the clamp jaws are rotated together with the beveled driven gear, the clamp bodies are moved toward or away from each other to clamp or release a workpiece, respectively.

An exemplary manipulator of a robot includes a fastening seat defining two guiding grooves, a driving mechanism disposed on the fastening seat, two transmitting plates respectively received in the two guiding grooves and cooperating with the driving mechanism, and two detecting bars each fixedly connecting with a corresponding transmitting plate. A detecting pin is fixed on each of the detecting bars. Under a driving action of the driving mechanism on the transmitting plates, the transmitting plates are activated to slide in the guiding grooves to cause the detecting bars to move close to or apart from each other, whereby a distance between the two detecting pins is automatically regulated.

A system and method for measuring performance of an electronic product using a measurement control device that connects to a measuring machine and a display device. A component of the electronic product is determined according to a coordinate array, and a physical factor of the component to measured is determined according to performance specifications of the electronic product. A sensor corresponding to the physical factor of the component is selected from sensors of the measuring machine, and a physical factor of each the component is measured by the selected sensor. The system indicates whether the electronic product is workable or unworkable by comparing the physical factors of the components with the performance specifications of the components, and generates a measurement report for evaluating the performance of the electronic product according to the indication results.

An exemplary manipulator of a robot includes a detecting bar including two detecting pins and a regulating mechanism for regulating the distance between the two detecting pins, a fastening seat supporting the detecting bar, a fixing device fixed to the fastening seat, a driving mechanism disposed on the fastening seat, and an adjusting element connecting the driving mechanism with the regulating mechanism of the detecting bar. Under a driving action of the driving mechanism on the adjusting element, the adjusting element rotates to cause the regulating mechanism of the detecting bar to regulate the distance between the two detecting pins.

In an electronic device and a method of correcting time-domain reflectometers, two channels of a time-domain reflectometer are connected to a corrector using cables, and the two channels are enabled to transmit pulses. Parameters Step Deskew and Channel Deskew of the two channels are zeroed. Resistance values of the two channels are measured simultaneously, and the value of the parameter Step Deskew of one of the two channels is adjusted according to the Resistance values of the two channels. Times of achieving the same resistance value of the two channels are measured after the cables and the connector have been disconnected, and the value of the parameter Channel Deskew of one of the two channels is adjusted according to the times of achieving the same resistance value. The adjusted values of the parameters Step Deskew and Channel Deskew are displayed through a display unit.

In a method for testing serial attached SCSI (SAS) ports of a server using a computing device, the computing device connects to an oscilloscope and a mechanical arm that is equipped with a test fixture having a probe. The mechanical arm controls the probe to be plugged into one of the SAS ports. The method adjusts an intensity grade of the SAS signals through the SAS port, and controls the SAS port to generate a SAS signal corresponding to the intensity grade. The test fixture obtains the SAS signal from the SAS port, and the oscilloscope measures test parameters of the SAS signal. The method analyzes values of the test parameters to find an optimal SAS signal, determines an intensity grade of the optimal SAS signal as a driving parameter of the SAS port, and accordingly generates a test report of the SAS ports.

An actuating mechanism includes first and second hollow outer shafts, two rotating wheels located between the first and second outer shafts, and an inner shaft received in the second outer shaft. Each of the first and second outer shafts forms a connecting portion at one end thereof. Each connecting portion defines two receiving holes. Each rotating wheel includes a body and a rod extending through the body. The bodies of the rotating wheels are in contact with each other. Two ends of the rod of each rotating wheel are correspondingly received in the receiving holes of the first and second outer shafts to connect the first and second outer shafts together. One end of the inner shaft contacts the rod of one rotating wheel. The inner shaft is rotatable in the second outer shaft to drive the two rotating wheels to rotate.

In a method for optimizing an order in which certain points on a circuit board can be tested and evaluated, a coordinate system is established in a circuit diagram of a circuit board, and at least one locating point is preset. When an operator selects a signal path routing within the circuit diagram, the method can display the testing points in the selected signal path routing on a display device. After calculating the distance between each of the testing points and each of the at least one locating point, a group of distances is obtained. By comparing the distances, the minimum distance can be determined from the group of distances. The method further optimizes the order of the testing points according to the distance between each of the testing points and the locating point that consists of the minimum distance.

A method for configuring setting values of oscilloscopes selects manufactures for a first oscilloscope and a second oscilloscope, and sends a command of acquiring a type respectively to the first oscilloscope and the second oscilloscope using the control codes of the selected manufacturers, to determine if the selected manufactures are the actual manufacturer. The method sends a command of acquiring setting values, respectively to the first oscilloscope and the second oscilloscope, using the control codes of the selected manufacturers, receives and compares the setting values of the first oscilloscope and the second oscilloscope. The method changes the setting values of the second oscilloscope to be same or similar with the first oscilloscope, and writes the changed setting values into the second oscilloscope.
