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.

2-18GHz Instantaneous Frequency Measurement Unit
DR058-F2
Teledyne Defence & Space’s Instantaneous Frequency Measurement (IFM) module, also known as a Digital Frequency Discriminator (DFD), offers high speed frequency measurement across the full operating bandwidth.The IFM measures the frequency of RF signal present at its input and presents a result at its output as digital data. The RF input signal is conditioned by an RF amplifier that provides sufficient drive for the frequency resolving circuits. The raw video from the resolvers is digitised and processed into the required output format. There is additional timing and control circuitry which initiates the measurement process and provides handshake data to the host system processor.
