Logic Analyzer:
Nothing Else Works Like It  

Given that computers and all things electronic obviously run on electricity, you realize that the operation depends on the signal: on or off, (which translates to one or zero) for all functions. If you need to test a logic circuit inside one of your electronic gizmos, you need a piece of precision test equipment that is called a logic analyzer.

Circuit Testing Logic

This device tests the logic board circuits and will tell you whether or not the circuit is solid – no breaks in the harness or wiring of the section of the board that is being tested. The analyzer has probes that are positioned along the logic path in question. These probes are designed to not interfere with the signal – simple to observe, if you will, like a man on the sidelines, watching for the correct signals to be given. No interaction but rather just observing and recording the data.

After setting up the logic analyzer, the system waits for a particular ‘trigger’ or action to take place (if this, then that…). Once the desired signal is detected, the data is captured and converted to a designated format. This format can range from generating assembly code (remember the first computer programming language?) to the drawing of timing diagrams.

If the technician is properly trained, he or she can take this data and debug the system – or cause other actions to take place generated from the captured data. (Sounds quite James Bond-ish, doesn’t it?)

Logic analysis equipment is an absolute requirement for any company that is producing electrical equipment, for serious work or for games, that relies on faultless logic circuits for their end product.
