Profile: TRS RenTelco is a supplier of electronic test equipment. Our products are widely used in communications, R&D, semiconductor, and wireless industries. A frequency analyzer is an instrument used to analyze the properties of radio frequency (RF) electrical networks, filters, transmission lines, signal sources and general properties associated with the reflection and transmission of electrical signals. Analyzers are basically classified as scalar or vector network configurations. Analyzers are associated with frequency and time domains. Logic analyzer is an electronic instrument that displays signals in a digital circuit that are too fast to be observed and presents it to a user so that the user can more easily check correct operation of the digital system. They are typically used for capturing data in systems that have too many channels to be examined with an oscilloscope. Software running on the logic analyzer can convert the captured data into timing diagrams, protocol decodes, state machine traces, assembly language, or correlate assembly with source-level software.
