Editing Logic analyzer (section)

==Overview==
Presently, there are three distinct categories of logic analyzers available on the market:

* '''Modular''' LAs, which consist of both a chassis or mainframe and logic analyzer modules.<ref>{{cite web|url=https://www.keysight.com/us/en/product/16900A/logic-analysis-system.html|title=16900 Series Modular Logic Analysis System|website=keysight.com|publisher=Keysight Technologies, Inc.|access-date=30 March 2021}}</ref>  The mainframe/chassis contains the display, controls, control computer, and multiple slots into which the actual data-capturing hardware is installed. The modules each have a specific number of channels, and multiple modules may be combined to obtain a very high channel count. While modular logic analyzers are typically more expensive, the ability to combine multiple modules to obtain a high channel count and the generally higher performance of modular logic analyzers often justifies the price. For the very high end modular logic analyzers, the user often must provide their own host PC or purchase an embedded controller compatible with the system.<ref>{{cite web|url=http://literature.cdn.keysight.com/litweb/pdf/5990-7513EN.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://literature.cdn.keysight.com/litweb/pdf/5990-7513EN.pdf |archive-date=2022-10-09 |url-status=live|title=U4154A AXIe-Based Logic Analyzer Module|website=keysight.com|publisher=Keysight Technologies, Inc.|access-date=1 December 2017}}</ref>

* '''Portable''' LAs,<ref>{{cite web|url=https://www.keysight.com/us/en/assets/7018-01398/brochures/5989-5062.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://www.keysight.com/us/en/assets/7018-01398/brochures/5989-5062.pdf |archive-date=2022-10-09 |url-status=live|title=16800 Series Portable Logic Analyzer|website=Keysight.com|publisher=Keysight Technologies, Inc.|access-date=31 July 2014}}</ref> sometimes referred to as standalone LAs. Portable logic analyzers integrate everything into a single package, with options installed at the factory. While portable logic analyzers generally have lower performance than their modular counterparts, they are often used for general purpose debugging by cost conscious users.
* '''PC-based''' LAs. The hardware connects to a computer through a [[USB]] or [[Ethernet]] connection and relays the captured signals to the software on the computer. These devices are typically much smaller and less expensive because they make use of a PC's existing keyboard, display and CPU.
