Captured information is decoded from raw digital form into a [[human-readable format]] that lets engineers review exchanged information. Protocol analyzers vary in their abilities to display and analyze data.

Some protocol analyzers can also generate traffic. These can act as protocol testers. Such testers generate protocol-correct traffic for functional testing, and may also have the ability to deliberately introduce errors to test the [[device under test]]'s ability to handle errors.<ref>{{CitationCite web needed|title=Lab Protocol Analyzers |url=https://www.amilabs.com/labanalyzers.htm |access-date=January2023-06-30 2012|website=www.amilabs.com}}</ref><ref>{{Cite web |last=shivakumar |date=2020-12-18 |title=Where is Protocol analyzer used? |url=https://prodigytechno.com/where-protocol-analyzer-is-used/ |access-date=2023-06-30 |website=Prodigy Technovations |language=en-US}}</ref>

Protocol analyzers can also be hardware-based, either in probe format or, as is increasingly common, combined with a disk array. These devices record packets or packet headers to a disk array.
