Analog and Digital Circuit Tester.

This is a report on an automatic tester for signularly testing a plurality of different types of standard electronic modules. A test program is written for each type of standard electronic module and this test data is stored on cassette tape. As the tester is adaptable for testing different types of modules, interface and switching matrix between the tester and the module under test is accomplished by an interface card and a matrix of relays. A plurality of programmable power supplies and programmable waveform generators are provided in the tester and instructions on the cassette tape dictate the desired values and wave shapes to be supplied to a particular module under test. The cassette tape also has data which represents the acceptable output requirements of a module under test and a measurement system measures the actual outputs and a comparison is then made with the measured output and the desired output to indicate either failure or acceptance of the module under test.
