  • Publication number: 20190154565
    Abstract: Methods are presented. Signals are sent into a first surface of a structure using an ultrasonic transducer. Ultrasound response signals are received at the ultrasonic transducer. A portion of a second surface of the structure is heated while the ultrasonic transducer is sending signals into the first surface, wherein the second surface is on an opposite side of the structure from the first surface. Infrared images of the portion of the second surface of the structure are taken after heating the second surface.

  • Patent number: 8351338
    Abstract: A test system for testing a communication system having a plurality of communication links is disclosed. The test system has a single tester for performing various measurement and diagnostic tasks on a single link. The test system also has a switching system for independently testing any link by coupling the tester into any one link. The tester is coupled into the link by coupling the tester input to the link's transmitter and the tester output to the link's receiver. The switching system couples the tester such that all remaining links of the communication system have a unique one of the plurality of transmitters coupled to a unique one of the plurality of receivers, whereby the operation of the communication system can be maintained while testing individual links.

  • Patent number: 7668233
    Abstract: In accordance with illustrative embodiments, methods and apparati, which determine jitter are described. In one example embodiment, a method includes receiving a signal, wherein the signal comprises a first data pattern which was generated at a first bit rate. The method also includes sampling the signal at a second bit rate to generate a second data pattern. The period of the second bit rate is different from the period of the first bit rate. The method also includes comparing the first data pattern and the second data pattern to determine differences between the first data pattern and the second data pattern. Furthermore, the method includes determining jitter in the signal according to the differences between the first data pattern and the data second data pattern. In other embodiments, by using two different bit rates to determine jitter, jitter can be determined in communication systems in a convenient and cost effective manner.

  • Patent number: 7434116
    Abstract: A testing apparatus for testing optical components includes an optical transmitter, an optical attenuator, an optical power meter and an optical receiver which are substantially rigidly coupled in a fixed relation to each other within a single housing. The system permits the common control of all the optical components such that calibration, testing and troubleshooting may be performed using a common user interface. The testing apparatus is unitary, compact and portable, and is a much more robust testing apparatus than conventional schemes.

  • Patent number: 7187435
    Abstract: An error analysis tester for an optical component includes an optical transmitter, an optical attenuator, a port, a receiver, a processor and a graphical display. The optical transmitter and optical attenuator produce a test signal at a plurality of selected optical power levels. The port is configured to output the test signal to the optical component and to receive a version of the test signal from the optical component. The receiver determines errors in the received version of the test signal. The processor determines data points of a function associated with an error rate at each of the selected power levels and a line corresponding to the data points. The graphical display produces a visual plot of the data points and the corresponding line.

  • Publication number: 20030231707
    Abstract: A testing apparatus and method useful in measuring the performance of a receiver when receiving a relatively high frequency jittered signal. A relatively high frequency oscillator is locked to a relatively low frequency reference with intentional jitter induced by adding jitter to the relatively low frequency reference. A divide by N circuit and a phase/frequency detector are used to detect discrepancies between the relatively low frequency reference output of the oscillator and to generate a signal used to keep the oscillator locked to the relatively low frequency reference. The addition of the jitter to the relatively low frequency reference may be controlled through digital or analog means.
