Unformatted text preview: ECE 214 : Analog & Digital Laboratory 2 Experiment 3: Logic Analyzer Familiarization 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. The 16 channel probes are connected in front of the logic analyzer via a ribbon cable. The probes are numbered from 0 to 15 corresponding to a channel number. Each probe is probes are numbered from 0 to 15 corresponding to a channel number....
