Digilogic’s Communication Tester is a modular, COTS, multifunction, programmable, benchtop Automated Test System (ATS) that supports a wide range of real-time RF and microwave stimulus, Test and Measurement (T&M) applications. Featuring a unique, real-time modular Software Defined architecture, intuitive touch screen interface and industry leading programmability, one system can replace over a dozen “boxed” T&M Instruments and test system components to significantly reduce T&M system Size, Weight, Power and Total Cost of Ownership, while dramatically improving measurement throughput.

Developed in collaboration with National Instruments, this system seamlessly supports applications from 250 kHz to 6 GHz with “in-the-box” upgrades that can extend the measurement upto 26.5 GHz frequency range.
