  • Circuitry for synchronizing a multiple channel circuit tester
    Patent number: 4660197
    Abstract: Quickly synchronizing adjustable delay circuits for a multiple channel tester by using a timing pulse that has reached the end of a given path in the tester to trigger the following timing pulse of a timing generator, thereby providing oscillating timing pulses having an associated frequency related to the propagation delay associated with the particular path, comparing the associated frequency with a reference frequency and adjusting a delay provided in the path until the associated frequency matches a desired frequency.
