Transmit/Receive Unit




The Transmit/Receive Unit (NSI-RF-TRU) features improved integration for range automation. Like the RTM, the TRU allows automation of configuration changes while simplifying system operation. The TRU allows the range operator to switch configurations without changing RF cable connections, thereby reducing errors and improving productivity.

The Transmit/Receive Unit is available in various configurations depending upon automation requirements. The TRU provides a wide range of options and modules for automating any type of antenna range. TRU modules combine high quality RF components and switches to provide a flexible platform for a wide variety of antenna range configuration control.

TRU modules incorporate switchable amplifiers, couplers, mixers, programmable step attenuators and other RF elements that may be combined in a variety of ways to create a highly automated antenna range. TRU modules are more highly integrated than RTM modules and are capable of being mounted on the probe carriage for some scanners.

    TRUPanel Software


    The NSI-RF-TRU communicates with a host computer using a LAN interface. The message-based protocol and object-oriented software provide a modular, easy-to-use environment for antenna range automation.

    The TRUPanel application provides a virtual front panel for the user to configure and monitor status of the TRU. Multiple TRUs in a system are easily controlled by the TRUPanel software. The NSITRU.DLL software allows custom automation solutions to be developed for a wide range of platforms including NSI 2000 Scripts, VB and VBA.
