What does the logic analyzer exactly do? It is a test instrument, whose purpose is to test complex digital and logic circuits. For many users, they are a godsend which enables them to investigate and understand how exactly these circuits operate. What it does, in principle, is let you see traces of logic signals, so that you can visualize multiple lines in the logic circuit at the same time.
How exactly is a logic analyzer different from an oscilloscope? An oscilloscope can do much of what the logic analyzer can do – but it cannot do so for many signals at the same time. If you want to see the relative timing of a multitude of signals at once, then the logic analyzer is the only way to travel. Some modern oscilloscopes do incorporate a few logic analyzer functions – they are called a mixed signal oscilloscope. However, not all such models will be able deliver the same functionality as a logic analyzer in you system.
What makes saleae logic analyzers stand out from the crowd is their ultra-portability and easy storage. The smallest model is a petite 1.66" x 1.66" x 0.39" – but even the largest model is only 3.6" x 3.6" x 0.59". Moreover, the saleae logic software works on any Windows, Mac or Linux operating system, so that cross platform work is simply not an issue. Finally, in contrast to most competing logic analyzers, saleae logic can record continuously.
Additional applications included in the saleae logic analyzer, which others lack, include an ability to decode multiple protocols at once – while still simultaneously displaying the original waveform. What this means for the user, is greater ease in comparing data than with dedicated protocol decoding tools, meaning that a great saving is affected in his time and his employer's money.
The saleae logic analyzer also has an application enabling microcontroller peripherals to be debugged, rapidly speeding up the troubleshooting process by pinpointing the location of errors – an especially useful feature when several different parts are hyper reacting to each other simultaneously.
Finally, the saleae logic analyzer also functions as a USB-based data logger. The User Interface (UI) records and analyses the data easily, saving the user much time and frustration.
