34MHz to 4.4GHz Frequency Synthesizer
-
A serial controllable synthesizer that will output any frequency between 33MHz to 4.4GHz. Arduino Pro Mini + ADF4351. It's a frequency generator that you control using serial commands. The synth has a built-in pre-programmed Arduino Pro Mini that runs a commands parser so you can set any frequency simply by sending is over the serial port. It can be run on voltages from 3,3V to 5V and takes about 140mA of current. There are two complimentary 50 ohms outputs that give out 0dBm. The output is pretty flat over the entire frequency range. It has a stability of 2.5ppm (parts per million) or better when using the built-in TCXO 10MHz reference.

-
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.

Redundant Frequency and Timing Systems
-
A unique feature of our frequency standards and distribution amplifiers is that the two separate parts of the redundant system are identical and can easily be inter-changed, for maintenance purposes. What we mean by this is that that we don't have a "Master" unit and a "Slave" unit. Whatever unit is powered up first becomes the master unit and the other becomes the slave unit.
