Introduction
The HI-4433 series comprises a family of battery-operated broadband radio
frequency (RF) isotropic field probes designed for use in making RF exposure
measurements in the vicinity of broadcast facilities and industrial RF sources.
These probes use optical isolation to minimize field perturbation during
measurements. Each probe in this series has characteristics that optimize its
performance for a particular application. Model number differentiates individual
probes for example HI-4433-XXX, where XXX defines the specific probe.
Each HI-4433 series probe assembly consists of a spherical casing containing
the sensor mounted on one end of a shaft. The other end of the shaft is attached
to an extrusion that houses the electronics. The sensor and electronics housing
operate, and are calibrated, as a unit. Since the appearance and layout of the
electronics housing are the same for all probes in this series, both the probe
assembly and the housing are coded with identical serial numbers to prevent
mismatch.
HI-4433 series probes measure the field strength in each of three axes. They
perform a vector addition calculation on the readings and send the result to the
readout via a fiber optic cable. Data from each axis can be viewed individually, or
can be combined. The measurement capability and frequency response of
HI-4433 series probes depend upon which model is selected. In addition, both
magnetic and electric field probes are available.
