AR’s Electric Field Measurement System

The RF/Microwave Instrumentation division of AR Worldwide is introducing a new electric field measurement system with a number of outstanding characteristics. When compared to other small probes, the new Starprobe™ offers excellent flatness from 0.5MHz to 2.4GHz; and that range can be extended down to 100kHz and up to 4.2GHz when applying calibration factors. The Starprobe, which is rated for continuous duty with no batteries to charge or replace, provides good accuracy without the need for correction factors.

The compact size of the Starprobe allows its use in locations that will not easily accommodate larger probes. Small probe size is also desirable in many free space applications, as it eliminates the field perturbation errors and the uncertainty normally introduced by reflections from larger resistive-lead-separated metal electronic housings that are exposed to the electric field.

The electric field-measuring system consists of two parts, the probe and probe interface. The probe is positioned in the electric field that is to be measured. The probe interface is remotely located, and is offered in a 19” rack-mountable enclosure, 1.75” high. The two parts may be separated by up to 100 meters using fiber optic cables. They are provided together in an Electric Field Probe Kit with 10 meter fiber interconnect cables.

The probe interface offers a variety of common electrical interfaces (USB, GPIB, RS-232 -19,200 baud) for easy access via a personal computer. The system is also supported by availability of a separate display to offer stand-alone operation without a computer interface. The display can work with one to four electric field probe kits.

The new Starprobe is backed by AR Worldwide’s global support network and three-year warranty.
