    摘要: A differential signal transmission device transmits N differential signal pairs from a differential signal generator to a number of receiving terminals. The N differential signal pairs include N positive signals and N negative signals. The N positive signals are clustered at a first positive clustering point. The first positive clustering point is connected to a second positive clustering point via a first matching resistor. The second positive clustering point is grounded via a first grounding resistor, and outputs a number of positive signals to the number of receiving terminals respectively. The N negative signals are clustered at a first negative clustering point. The first negative clustering point is connected to a second negative clustering point via a second matching resistor. The second negative signal clustering point is grounded via a second grounding resistor, and outputs a number of negative signals to the number of receiving terminals respectively.

    摘要: A signal integrity test system and method uses an oscilloscope to test a signal on each test point of a transmission line, obtains test parameter values of the signal on each test point, and compares the test parameter values with preset standard values. If any test parameter value does not match a corresponding preset standard value, a time-domain reflectometer is used to test an impedance value of the test point. If the impedance value matches a standard impedance value of the transmission line, the system and method determines the signal on the test point satisfies integrity requirements.

    摘要: A clamping apparatus includes a motor, a first cone gear secured to a shaft of the motor, and two clamping bodies attached to opposite sides of the motor. Each of the clamping bodies includes a second cone gear meshing with the first, a threaded post fixed to the second cone gear, a carriage threadedly connected with the threaded post, and a clamp arm fixed to the carriage. The motor rotates the first cone gear, and in turn the second cone gears and the corresponding threaded posts. With the rotation of the threaded posts, the carriages move towards or away from each other, whereby the clamp arms cooperatively acquire an object between the clamp arms, or release the object therefrom.
