The Bridge12 Frequency Measurement System (FMS) is a millimeter-wave, terahertz frequency counter to measure the frequency of your source, be it a gyrotron, TWT or a solid-state device. Based on a heterodyne receiver architecture the FMS can accurately measure the frequency to an accuracy of +/- 1 MHz. The FMS is available in multiple waveguide bands up to 1 THz. The system is designed for easy remote monitoring through a computer or a mobile device.
This system is designed for fast frequency measurement to provide feedback to control the source frequency in applications that require high frequency stability. Directly measuring the output of the source frequency is beneficial in many systems like Amplifier Multiplier Chains (AMC) where the output frequency is inferred from the input drive frequency. The FMS can also detect spurious signals and unintended harmonic outputs coming from such devices. This can be very beneficial in Electron Paramagnetic Resonance (EPR) and Dynamic Nuclear Polarization (DNP-NMR) spectroscopy setups. The FMS can also be employed in production lines for microwave, millimeter-wave and terahertz sources such as TWTs or klystrons or in fusion facilities with multiple gyrotrons.
Compact Terahertz Counter
The FMS is a compact system that can be used as a table-top instrument or it can be mounted either on a terahertz transmission line for inline real-time monitoring of the source frequency. The key dimensions of the FMS are available here.

Automatic Search and Tracking
The FMS software is designed for stand-alone operation on a tablet or a mobile device with fast data streaming. The software can conduct a frequency search to determine the source frequency or track a given frequency over time. THe system comes equiped with an Android tablet for easy remote operation. Apps for Android and iOS phones are also available.
Integration with End User Application
The FMS software is designed for stand-alone operation on a tablet or a mobile device with fast streaming of data. An inbuilt API is available for integrated control of the FMS from the user application. For instance the FMS can be easily integrated into the Plasma Control System (PCS) in a nuclear fusion machine to monitor gyrotrons in an electron cyclotron (EC) system.
