INTRODUCTION The B & K-Precision model 560 Programmable IC Tester allows personnel of varied skill levels to perform fast, uncomplicated, and versatile IC testing. The powerful microcomputer-based operating system of the model 560 allows efficiency in IC testing not previously possible with moderately-priced testers. The instrument tests over 90% of the most popular digital ICs (including many RAM and ROM ICs), due to an extensive internal library of IC test data. To set up IC tests, you merely enter the desired testing mode, the IC generic number, and press the TEST key. The tester automatically arranges IC pin-out and test voltage levels. The tester also has provisions for in-circuit IC testing. This is feasible via a special feature that applies current backdrive to the in-circuit IC's surrounding circuitry, allowing implementation of the tester truth table in most cases. In addition to standard IC tests, the instrument also tests ICs contained on board assemblies where inputs of a device may be tied to logic states. Compare testing allows testing where pins may be tied to Vcc or ground; a condition that would cause "good" ICs to test "defective" with standard testing. The tester records (stores) the unique response of a reference IC and its circuit, and then uses this response for testing similar untested ICs. This feature is offered in both single-device (Device Compare) and multiple-device (Board Learn) modes. Using the Board Learn mode allows you to record the responses of all digital ICs contained on a board in one continuous operation. This mode also allows user indexing of IC and board nomenclature, thereby maintaining a convenient record of board contents for future use. Direct, "no guesswork" IC test results are shown on the fluorescent alphanumeric display which reads "PASS", or "FAIL", showing which pin(s) tested defective. Using clear, informative directives (via the display and LED arrays), the tester guides the user through test procedures. Aural prompts are also provided to indicate the validity of an entry and device test results. These prompts allow even inexperienced users to perform tests with confidence; an important consideration in production situations where user apprehension can lead to lowered productivity. Other time-saving features include a "retest" key that allows repetitive testing of similar ICs without re-keying the IC number or family. Also, certain keys are of the "soft" design, assuming different functions at appropriate times. This design simplifies operation by reducing the number of controls. The model 560 is designed with tomorrow, as well as today, in mind. Since the IC library is contained in EPROM software, periodically-expanded IC Library EPROM ICs are offered by B & K-Precision as new ICs are introduced. Your unit can be updated to test the newest ICs by simply replacing the library EPROMs. An optional Software package is also available which allows programming of custom devices not contained in the IC Library via a personal computer and the tester's RS-232 port. Advanced engineering, quality construction, and user-oriented concepts and design make the model 560 an exceptionally superior and effective instrument. To gain the most effective use of this instrument, we recommend that you study the entire contents of this manual.
