What Is A Logic Analyzer And How Does It Work?

A logic analyzer is a type electronic testing device which is used to test digital circuits to make sure they work properly. A logic analyzer displays the logic levels (binary numbers 0 or 1) of signals in the circuit which are too fast to be measured by any other type of equipment. An oscilloscope cannot measure the vast number of signals that a typical digital system possesses. A logic analyzer is a necessity for digital technicians because it captures data which cannot be captured by any other type of test equipment.

A logic analyzer is connected to the digital system via a series of probes. These probes ensure a good connection, both mechanically and electrically. They're specially designed to be as transparent as possible so the electrical signal is not altered. After setting up the logic analyzer the trigger condition is set. A trigger condition can be almost anything you can think of, from triggering on an exact HTTP packet to triggering on the rising edge of a signal. After capturing the data the logic analyzer's software can convert it into multiple formats. These formats can range from assembly language to timing diagrams. A trained technician can take this converted data and use it to debug the digital system.


Logic analysis equipment is used extensively in the digital chipmaking and networking industries where digital circuits have to work exactly as designed.
