Field Probes & Field Monitoring

Field Probes & Field Monitoring

An Advancement in Laser-Powered Electric Field Probes

The FL8000 Series field probes offer a three-in-one solution capable of measuring continuous-wave, pulsed, and modulated electric fields. Covering 5 kHz – 60 GHz, the FL8000 Series works great in commercial, automotive, military, and aviation applications. Each field probe is an electrically small, separable axis sensor capable of measuring both continuous wave and pulsed electric fields offering a unique bandwidth, sensitivity, and dynamic range. Functionality that historically necessitated several types of field probes is now encompassed in a single product.

This series offers exceptional linearity and dynamic range performance to enable the accuracy required for even the most demanding testing. With fiber power connectivity, the FL8000 Series provides an easy migration path, all while delivering the reliability that has made AR the world leader in field monitoring.

The Field Probe kits contain a laser probe interface, and everything needed to operate its associated Field Probe.

Laser Probe Interface

The FI8000 interface provides both power to and communication with the FL8000 series probes. A low-level loop back fiber optic connection is used to sense unexpected disconnect of laser driven fibers to ensure user-safe operation. As an additional safety measure, shuttered connectors are used on all fiber optic connections to and from the probe.

The FI8000 can be used with the FM7004A Field Monitor (using the provided 0.5-meter fiber optic cable) or a PC by direct communication using the IEEE-488 (GPIB), Ethernet, USB 2.0, RS-232 or Fiber-Optic Serial interfaces.

Field Monitoring

Model FM7004A is an E-field control center that offers monitoring, display, and alarm capabilities for immunity-test environments. Exceptionally precise with auto-recognition to adapt to laser powered probes. The FM7004A is self-calibrating and is programmed to be self-correcting. The unit allows field-strength measurement at up to four probe locations simultaneously with results displayed on a backlit color LCD. Choose from any field probe with sensitivity from 0.4 to 1000 V/m, 0.012 - 17 A/m, and frequency response from 5 kHz to 60 GHz.

Up to 4 tables of correction factors containing up to 30 different frequency points can be stored in the FM7004A. From the menu-controlled front panel, call up composite field readings from E-field probes, including a laser powered E-field probe, or choose readings from each axis of a three-axis probe.

The FM7004A field monitor provides four digital interfaces (USB, GPIB, RS-232 and Ethernet) and a highly readable user configurable, graphic, liquid crystal display. Menu options are at your disposal. Communication from the chamber to the FM7004A is through fiber optic cables.
