66 -- ANECHOIC TEST FACILITY SOL DAAC71-97-R-0002 DUE 110796 POC Contract Specialist, Joe Santillo, (717) 895-7517, Contracting Officer, Joyce Bednar, (717) 895-6369 (Site Code DAAC71) Tobyhanna Army Depot identification/reference number DAAC71-97-R-0002 is issued for informational purposes, seeking sources that can provide the following anechoic chamber turn-key facility: 1. General: The chamber facility shall consist of a TEMPEST shielded chamber shell with absorbent material within, together with all hardware, equipment and software necessary to test antennas according to the following specifications to successfully test a specific direction finding antenna array to the desired specifications and be expandable for future workload projections. SOW also specifies the training and documentation required for this facility. 2. Electrical Specifications a. Frequency range shall be from 500 Mhz to 18 Ghz. b. Quiet zone reflectivity specifications shall be as follows: 500 Mhz -45 db, 2 Ghz -45 db, 8 Ghz -45 db, 18 Ghz -40 db. Quiet zone shall be 4 feet spherical minimum centered at least 35 feet from source antenna. c. TEMPEST shielding shall be as follows: 14 Khz - 200 Khz -25 db, 200 Khz - 500 Mhz -40 db, 500 Mhz - 18 Ghz -60 db. d. Path length shall be 35 feet minimum from source antenna to receiving antenna. e. Phase front shall be a spherical wave phase front conforming to a geometric arc to within one electrical degree. f. Source frequency selection shall be automated. g. Source antenna selection shall be automated if multiple source antennas are utilized. h. Power handling capability shall be .5 W/sq in minimum for absorbent material. 3. Physical Specifications a. Turn key facility shall include chamber proper, control and equipment rooms, all physically connected to each other. The chamber shall be installed/erected within an existing building. Overall chamber dimensions cannot exceed approximately 25'hx35'wx70'l. b. Facility shall be equipped with fire alarm, automatic fire suppressant system, security measures and electrical power. Facility shall be ready to test example array when complete with NO further modifications or work required. 4. Training shall be provided for up to 5 personnel and shall include operation, maintenance, calibration and utilization of the chamber to its full capabilities. Software operation and modification and configuration shall be included. 5. Software shall include source code so as to be customer maintainable and changeable. 6. Equipment shall meet all safety and quality standards applicable. 7. Documentation shall consist of all equipment and software documentation necessary to calibrate, repair and alter said items. Documentation verifying all aspects of chamber operation shall also be included. 8. Calibration: Calibration shall be performed as necessary to assure proper operation for testing. 9. Acceptance Testing: All chamber electrical characteristics shall be verified as constructed as far as shielding, quiet zone specifications, equipment and software operation and total configuration options. Final Acceptance will conclude with a demonstration test of the array/system according to a given Acceptance Test Procedure with corresponding output verifying passing status on a known good array previously tested at another sight. 10. DISCO clearance will be required for any sources that would be interested in submitting a proposal should a solicitation be issued in the future. Interested sources that provide the above-described facility should provide a description of their capabilities within 10 days of publication of this notice. This is not a solicitation synopsis.
