# Protocol Analyzers

Electronic system engineers use protocol analyzers to capture signals and data over a communication channel, monitoring and analyzing this information to strengthen system security. Protocol analyzers are a type of electronic test equipment that can be hardware, software, or a combination. Protocol analyzers use data measurements to supplement antivirus programs, firewalls, and anti-malware systems. Find top-quality used and refurbished protocol analyzers from major manufacturers such as Keysight Agilent, LeCroy, and Rohde & Schwarz at ValueTronics.com.
