Teledyne Defence & Space
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.

Tech-Aid Products
This test fixture provides the necessary panel controls, switching and cable pin-outs required to test the KPI-552/KPI-553/A series of HSI's as described in their respective maintenance manuals. This fixture will serve as the "Instrument Bench Tester" and does have the required differential resolvers and relay switching. Panel jacks are provided for the Heading, Course, RMI and ADF synchro sources that are external to this fixture. The use of external synchro sources serves to minimize the cost of this panel. Additional items incorporated on the panel are test jacks to monitor the meter drive voltage and current as well as a momentary switch to open the meter drive and this serves to verify sticky meter stops. The fixtures rear panel provides for all power inputs as well as an I/O connector if the shop desires to interface an external synchro panel.
