The ATTI Z2005S is a dedicated transmission line test system for tests from 10 MHz to 20 GHz (or from 10 MHz to 40 GHz optionC40). It is configured in a rugged, transportable container. The system is self-contained for ease of use and is ideal for accessing transmission lines in difficult-to-reach installations such as aircraft. Although all testing can be done automatically, full manual capability is retained.
