The Amplifier Research Model FS4010 is a compact pre-compliance test system designed for RF radiated immunity and emissions testing.
It is designed for applications requiring field strengths of up to 10 volts per meter (V/m) with 80%AM or 20 V/m CW. 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, dual directional couplers, an RF switch matrix, interconnecting RF cables and connectors and a system control PC pre-loaded with radiated 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 system components of the FS4010 models are listed in Table 1 (below). This lightly used model comes with 2 broadband power amplifiers covering the frequency range 80 MHz – 3 GHz.
The immunity and emissions test software provides automated testing, data collection and report generation. The simple user interface facilitates test parameter selection and setup of a “Thresholding” mode for pre-compliance investigation of equipment susceptibility. Control of closed loop field leveling has also been incorporated making the program suitable for pre-compliance troubleshooting, testing to the IEC-801-3 (1984) standard, and MIL STD 461 type testing using a broadband electric field monitoring probe.
Instrument control is provided via a National Instruments IEEE-488 interface card. Automatic data acquisition for EUT monitoring and data collection is supported by a National Instruments data acquisition card to allow the user to automatically collect and record, for report generation, EUT performance data from up to 8 digital and 16 analog channels (pass / fail conditions). An additional 8 digital output lines are available for EUT control or reset.
The test cell provides access via 9 filtered lines. Additional line access can be added by the user on a user modifiable access plate. The Model FS4010 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 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 5.7m (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.
Equipment supporting the cell is housed in a rack cabinet of desk configuration with nominal footprint of 1.8m (W) x 1.0m (D). This configuration provides a convenient tabletop location for the PC, monitor, keyboard, mouse, and printer.
