Pre-Compliance Test System, 80 to 1000 MHz, 10 V/m

The Model FS3000A is a plug and play pre-compliance test system designed for RF radiated immunity and emissions testing. It is designed for applications requiring a field strength of up to 10 volts per meter (V/M) with 80% AM modulation. It consists of a solid state broadband RF power amplifier, a semi-anechoic test chamber, a broadband electric field monitoring probe, a signal generator, a power meter, a dual directional coupler, a color printer, interconnecting RF cables and connectors and a system control PC pre-loaded with radiated and conducted immunity and emissions testing software to automate the testing process. It also includes a pre-amplifier and interconnecting cables for use with a user supplied Spectrum Analyzer.

The Model FS3000A free space test system affords a cost effective method of equipping an automated pre-compliance radiated immunity and emissions test facility using an economical compact free space test cell suitable for an EUT size up to 1.0 meter per side. The test cell is assembled at the user’s site and offers the user a large access door (1.8m (H) x 1.0m (W) opening) with viewing window, interior illumination, fiber optic access pipe, 15 amp, 110/220 VAC single phase filtered mains connection, door open safety interlock and Type N coaxial thru connector. The test cell enclosure is nominally 4.5m (W) x 2.6m (H) x 2.4m (D).

The interior of the cell is lined with a radio frequency absorbing material to create a self contained semi-anechoic enclosure. The field inside the cell is generated by an internal log periodic antenna. Field polarization is switchable for vertical or horizontal. An optional bowtie antenna and appropriate amplifier may be used to test from 27 to 80 MHz.

All peripheral equipment primarily is configured for 115VAC, * 10% 60Hz (single phase). Other voltages are available. Equipment supporting the cell is housed in a rack cabinet of desk configuration with nominal footprint of 1.5m (W) x 1.0m (D). This configuration provides a convenient tabletop location for the PC, monitor, keyboard, mouse, and printer.
