LibertyGT 1211B


LibertyGT 1211B Modular, COTS, Benchtop ATS

The RADX® LibertyGT® 1211B (LGT1211B) is a modular, COTS, multifunction, programmable, benchtop Automated Test System (ATS) that supports a wide range of realtime RF and Microwave Stimulus, Test and Measurement (T&M) applications. Featuring a unique, modular Software Defined Synthetic Instrument (SDSI®) architecture, intuitive touchscreen interface and industry leading programmability, one LGT1211B can replace over a dozen “Boxed” T&M Instruments and test system components to significantly reduce test system Size, Weight and Power (SWaP) and Total Cost of Ownership (TCO), while dramatically improving Measurement Throughput.


RReplace MULTIPLE T&M “Box Instruments” with ONE LibertyGT
Benchtop ATS to REDUCE SWaP & TCO and IMPROVE Throughput

Developed in collaboration with National Instruments® and selected by Frost & Sullivan for a 2014 Global New Product Innovation and Best Practices Award, the LGT1211B supports applications from 100 kHz to 6 GHz with “in-the-box” upgrades that extend the measurement upper frequency range to 26.5 GHz.

The LGT1211B sets a new standard for cost-effective, high-throughput, multifunction, parametric test of commercial and military radios, avionics, wireless communications and other RF systems where the combination of user programmability, flexibility, performance, throughput, long life cycle support and low total cost of ownership is of paramount importance. The LGT1211B, when fully configured, provides the following capabilities for apps from 100 kHz to 6 GHz:
