DIGITAL ELECTRONICS TESTING sa INTEGRATED CIRCUIT TESTING sa LOGIC ANALYZER sa LOGIC PROBE sa LOGIC PULSER xx DIGITAL ELECTRONICS xx ELECTRONIC TESTING BCD word generator. Provides a simple, low-cost solution to efficient and fast testing of digital circuits and microprocessor input ports. Est. cost: $30. Build the Digilyzer, a small box which performs some digital analyzer functions (monitors logic levels at 8 inputs, monitors IC input/output, monitors memory locations on a bus, etc.). Est. cost: $50. Voltage tracker can monitor a voltage unattended, remember the direction of voltage fluctuation, or the arrival or non-arrival of a pulse. Est. cost: $25. How to silence a noisy computer. Tips from some of the chip manufacturers on how to eliminate electronic noise ("glitches") in digital circuits. The information is taken from their chip data books. Build your own TTL diagnostic aid. Test unit will tell you whether or not a TTL pulse has occured, although it will not indicate the duration. Features a test clip, test probe, mode and slope selector, etc. Est. cost: $100. Logic signal measurements. How to use an oscilloscope to make basic measurements in digital logic circuits. A digital measurement lab instrument. Part 1. Main frame power supply and readout with 20 MHz frequency counter module. Simple test instruments for digital circuits. Circuits for a slow-speed repeating trigger with an instant stop and a pulse detector that can double as a pulse-coincidence detector. Testing digital circuits. How to use commercial or homemade test devices to check digital IC's, either in or out of the circuit. Device to simultaneaously check out all 14 or 16 pins of an in-circuit DIP package. The IC can be a CMOS, TTL, DTL, RTL or other positive-supply digital logic. Est. cost: $19. Stalled-output detector circuit can be used as a building block to detect a stuck output or node in a circuit. The circuit detects the loss of a pulse train and could be applied in an IC tester, security system, power-fail detector, etc. Risetime tester circuit can be used to check the risetime of digital encoders without the use of a scope. A logical look at digital circuits. Tips on troubleshooting digital circuits for the professional electronics technician. How to troubleshoot digital circuits. Includes digital reference charts. Troubleshooting digital circuits. An introduction to the tools and techniques for working with digital IC's. Do-it-yourself test instruments. Pulse stretchers. Tip: Use the X-Y or vector mode to test the reset function of sequential logic circuits, microprocessors, etc. An adapter to turn a multimeter into a digital circuit tracer. Est cost: $4. | |||||||||
