An equipment for testing electronic circuitry

摘要

An equipment for testing electronic circuitry comprising: test connections to said circuitry; measurement means for generating test signals for application to said circuitry and monitoring response signals produced by the circuitry in response to the test signals, said test signals being applied and said response signals being received by way of said test connections; switches for switching the test signals generated to said test connections and the response signals produced to said measurement means; means defining the settings of said switches for a current test of a series of tests required to be performed on said circuitry; first memory means for storing the switch settings for the next test of said series following said current test; second memory means for storing the switch settings for the entire series of tests; and sequencer means for transferring (i) the next switch settings from said first memory means to said means defining and (ii) the switch settings for the test of said series following said next test from said second memory means to said first memory means, said sequencer means initiating the transferring in response to the receipt of a trigger signal from said measurement means indicating that test signals for said next test will be applied to said circuitry after a predetermined time.
