Introducing NeoScan
EMAG Technologies Inc. offers unique, versatile solutions for your RF test and characterization needs. The NeoScan family of turnkey field measurement systems provide a non-invasive method to detect and probe the electric and magnetic fields generated by your RF devices, antennas or subsystems. They utilize our patented electro-optic and magneto-optic probe technologies to sample and measure electric and magnetic fields without any physical contact, while providing a very large operational bandwidth and a very high spatial resolution.
Unlike conventional near-field scanning systems that require metallic pickup radiators or sensors, NeoScan probes are made of absolutely metal-free parts. Our field probes feature miniaturized optical crystal tips mounted on optical fibers. The combination of extremely small probe footprint and absence of metallic parts or interconnnects at the signal pickup area warrant the ultimate RF non-invasiveness. In addition to local field sampling, a NeoScan system can be configured as a near-field scanning system for mapping aperture-level or device-level field distributions with minimal invasiveness to the antenna or device under test. You can also use a NeoScan system as a real-time field detection system for sensing and probing electric and magnetic field waveforms in a variety of physical propagation media.
NeoScan systems can be used for a variety of RF test and evaluation applications:
- Non-invasive near-field mapping of RF devices, circuits and antennas
- System fault diagnostics through measurement of field emissions, leakage, coupling effects, etc.
- Compact near-field antenna range measurements
- Real time non-contact measurement of fields and signals in a variety of propagation media

NeoScan System Applications
Why Measure Fields?
Measurement of electric and magnetic fields has numerous uses and applications in different areas of RF technology. First and foremost, field maps shed light on the physical behavior of RF devices and systems. RF engineers typically use external measurement systems for high frequency characterization. For example, a network analyzer measures the port characteristics of a device. A spectrum analyzer captures the spectral contents of the signals at the input or output of your RF system. Antennas are traditionally characterized by their far field radiation patterns. Such external measurements do not reveal much about how signals, fields and waves evolve, build up and propagate inside a device from one port to another, or out into the free space.
Just as an oscilloscope probe measures voltages and currents at various points of an electronic circuit, imagine if you could measure electric or magnetic fields at any point inside or around a distributed RF system without perturbing them! That's what NeoScan exactly does for you.
