The W&G ANT20 3035/02 Acterna Advanced Network Tester is a modular, portable instrument for comprehensive network analysis and troubleshooting across telecommunications standards. It delivers multi-rate transmission testing from DS1 to OC-192c and E1 to STM-64c, with integrated SONET, DSn, SDH, and ATM capabilities. The platform combines a large color touchscreen display with Windows-based graphical interface for simplified operation in complex testing environments.
