EMAG Technologies Inc. utilizes a novel patented technology for real-time measurement of electric and magnetic fields. EO and MO modulation effects provide a unique means of sensing and detecting wideband RF and microwave signals in real time. Since the carrier signal is at optical frequencies, the modulating RF field can have substantial instantaneous bandwidths. [[NeoScan]] can probe and register complex temporal waveforms in real time. Since you measure fields rather than voltages or currents using a non-contact probe, [[NeoScan]] probes in effect exhibit an infinite impedance. This feature eliminates all the device loading concerns.

Our probe systems can be used as an instrument for real-time measurement of wideband RF signals in microwave circuits and systems. They can also be utilized in a unique way for a variety of other detection and sensing applications where the presence of metallic parts is highly undesirable such as directed energy and high power microwave systems. Using a robust, patented, optical processing technology, the probes can have standoff distances up to 50 meters from the physical location of the optical mainframe system. Due to the fast response of the EO crystal, it is possible to measure extremely high-bandwidth signals with the normal SNR limitations of wideband signal detection. Using this capability, EMAG Technologies Inc. has developed the world’s first fiber-based real-time polarimetric electric field sensor system for the measurement of high-power microwave signals. The figure below shows an example of a real time measurement of a 6.6ns pulse with 10kV/m peak field strength. The upper trace shown on the oscilloscope is the received signal, and the lower trace is the detected signal.
