Logic analyzer

What is logic analyzer?
A logic analyzer is an electronic instrument used to acquire and display multiple signals from a digital system or circuit. This electronic laboratory tester is designed to evaluate and display signals from electronic circuits under test to determine whether the circuit is working as intended and there are no faults. It works similarly to an oscilloscope, but it can capture multiple signals.

A logic analyzer captures, conditions, analyzes, and then displays a series of digital events generated by a particular electronic device or circuit. Once captured, the data can be rendered as decoded traffic, state lists, or even graphic images. Extended versions can save previous data and then compare it with new data sets to gain further insight into the activities of the circuit or system under test.

A logic analyzer also has advanced triggering capabilities that are useful for visualizing the temporal relationships between the many different signals in a digital system.

Logical analyzer categories:

PC-based - The logic analyzer hardware connects to a PC or other type of computer using a USB, Ethernet, or serial port. The main function of the logic analyzer hardware is data acquisition and signal conditioning, while all analysis and special functions are performed on the software side.

Portable - Also known as a standalone logic analyzer that integrates all components in a single package, it usually comes as it is and is usually not upgradeable compared to the modular logic analyzer that can swap functional modules or the PC-based one that comes via software -Updates can have any number of feature enhancements.

Modular - This type has multiple module ports to add more channels and functions to the system. The housing or frame consists of the display, computer, controls and expansion slots for additional modules. This type of logic analyzer is typically more expensive than the other two types, but it can serve both roles as it is somewhat portable as it is not bolted down and can also be connected to a PC for additional software functionality.
