Range Automation System
ELE-RAS
-
NSI-MI’s Range Automation System (ELE-RAS) has been specially designed to automate the time-consuming tasks associated with antenna range reconfiguration. This system eliminates operator intervention for range reversal, band switching, and power level optimization in antenna measurement facilities. This hands-off approach reduces uncertainty, extends the life of sensitive components, reduces RF leakage, and dramatically increases throughput and productivity. The modular architecture allows each ELE-RAS system to be optimized for maximum performance. ELE-RAS is software and receiver agnostic, meaning that it can be used to improve efficiency in virtually any antenna test range. Standard solutions are available for 20 GHz and 50 GHz applications. The ELE-RAS architecture also supports custom solutions to meet your unique measurement challenges.
