Radio Frequency Cable Tester
RFCT
-
Textron Systems’ Radio Frequency Cable Tester (RFCT) allows for on-site testing and maintenance for radio frequency (RF) transmission paths within a platform. Using preconfigured databases of sweep parameters and pass/fail criteria, the RFCT quickly determines the status of installed RF cables. The RFCT checks each cable’s performance characteristics to include voltage standing wave ratio (VSWR), insertion loss (IL), phase and phase matching. If a cable fails a test, the RFCT automatically determines the distance-to-fault (DTF). With its intuitive touchscreen-based user interface and lightweight, ruggedized packaging, the RFCT is the gold standard for operational-level RF cable testing.

Radio Frequency Scoring Tool
RFST
-
The Radio Frequency (RF) Scoring Tool (RFST) takes the guess work out of RF environment simulation. During RF environment simulation, the RFST provides clear persistent scoring and recording of the RF simulator’s performance. The RFST digitizes all RF signals in the form of digital Pulse Descriptor Words (PDWs) and associated In-phase/Quadrature (I-Q) data. This massive data stream is recorded for later (Post-Scenario) Analysis. Additionally, the RFST provides a real-time visual display of the accuracy of the RF output, easily visible through straight forward real-time indicators. The post analysis tool set allows an unlimited number of users to simultaneously assess previous RF simulator performance with compelling visual representations. The RFST is a perfect complement to our A2PATS product line offering everything you need for comprehensive environment simulation and analysis.
