2-18GHz Instantaneous Frequency Measurement Unit
DR024-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.

8-Channel, 100 MHz Counter/Timer/Frequency Meter Function Card
ProDAQ 3808
The ProDAQ 3808 function card, an enhanced version of the ProDAQ 3806 counter/timer function card, is designed to operate in one of three modes: pulse counter, frequency meter, or time interval counter. In the pulse counter and frequency measurement modes, users can process incoming signals of up to 25 MHz on each of the six channels. A time interval counter range is divided into six sub-ranges, covering times from 40 ns to 20000 s with a maximum resolution of 10 ns. For pulse-width measurements, the same ranges apply.

High Frequency Current Transformers
Osborne High Frequency Current Transformers operate at frequencies higher than 50/60 Hertz. Their purpose is to reduce high frequency system currents to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when high frequency current transformers are to be used for power measuring applications.
