Introduction The objective of this experiment was to learn how to use the HP54620A logic analyzer. Using two simple sequential logic circuits, logic analyzer was enabled to trigger on different conditions and display multiple logic signals Theoretical Background The functionality of a logic analyzer is the same as that of an oscilloscope. But oscilloscopes can only display a limited number of channels (in our case two). In the case of complex logic circuits we are sometimes required to observe several signals at the same time. Logic analyzers alleviate this problem by displaying several signals simultaneously. The logic analyzer contains probes that can be directly connected to parts in the circuit. The main advantage of a logic analyzer is that it has 16 channels as opposed to an oscilloscope with 2 channels. Therefore logic analyzers are very useful in debugging complex circuits. Logic analyzers are capable of displaying signals as traces. They can collect data at high speed making it possible to test circuits at full clock speed.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
