An automatic testing instrument determines the operational status of an equipment under test on a real time basis by first generating from a stimulus memory a pattern for stimulating the equipment which, when stimulated by the pattern, sends out a response pattern, which is transmitted back to the automatic testing instrument. The testing instrument then takes the received response pattern and compares it with a pre-determined pattern stored in a comparator. If the response pattern differs from the expected pattern, an error signal is sent to indicate to the user of the testing instrument that the equipment under test is operating erroneously, for that particular pattern. |
