Wavecontrol distributes in Spain and Portugal the RADISENSE isotropic field probes from DARE.
RadiSense®: Robust - Reliable - Small - Without Battery With the aim to carry out accurate field strength measurements, the probe must be small compared to the wavelength of the measured signal. If the size of the probe is too great it will cause resonances at higher frequencies, which counts for a significant share in the total measurement uncertainty.
Reliable
So, in order to obtain reliable and precise measurement results, should the size of the probe be as small as possible.
Small
With the introduction of the field strength RadiSense® sensors in 1999 has ended all size related measurement problems. With a measurement volume of 75 cm3 and 1 cm3 and robust enclosures provide the probes for reliable measurements. By comparison, the current probes perform measurements with a volume ranging from 300 cm3 and 1000 cm3, which creats fundamental measurement errors.
Without batteries
Another disadvantage of the standard field probe is that they are fed by a battery. It is understandable that batteries are used. Galvanic wires influence the be measured field. But batteries are empty and often depleted when needed. For example, a battery-powered probe is useless for all night testing. Unlike other probes, the field strength sensor RadiSense® is powered by a high power LASER, whose light is transmitted to the probe by a fiber optic cable and feeds the the low-noise amplifier and a single microprocessor chip, reads the antennas and passes the measured values to a PC through a second fiber cable.
Software Support
The field strength RadiSense® sensors are supported by the RadiMation®, automated EMC measurement software. The RadiMon® control software is included with the system for stand-alone use. The probe can most commercially available EMC software driven by a Holaday® 4422 compatible instruction set.
Los modelos disponibles son:
- Radisense 4 GHz
- Radisense 6 GHz
- Radisense 18 GHz
Estas sondas necesitan de un centro de control para ser controladas y monitorizadas, RadiCentre.
