59 -- INDUSTRY PACKS AND CARRIER BOARDS FOR IF/LO ANTENNA SOL RFP-BF6083 DUE 021600 POC EJ Dotts, Contracting Officer, 617-496-7562, 617-496-7978(fax), edotts@cfa.harvard.edu The Smithsonian Astrophysical Observatory (SAO) intends to award on a sole source basis a contract to SBS Technologies, Inc. Modular I/O, 181 Constitution Dr., Menlo Park, CA 94025, per justification pursuant to FAR 13.106, Only One Responsible Source and No Other Supplies or Services Will Satisfy Agency Requirements. We require the following items: a) SBS part number VIPC618 (quantity 33), Industry Pack Carrier for 6U VME Bus optimized to reduce EMI emissions with filtered power lines and SCSI-2 Type connectors on extruded panel and meets VME specification C.1 for 6U form factor. b) SBS part number IP-Unidig-E (quantity 33), Industry pack with 24 input/output lines with linesafe ESD protection circuitry. c) SBS part number IP-Unidig-I (quantity 4), Industry pack with 24 flexible input/output lines and all input lines can be used to generate an interrupt. d) SBS part number IP-OptoAD16-BVP-1 (quantity 24), Industry pack capable of providing 16 single ended or 8 different channels of 16 bit A/D conversion with a full scale input range of +/- 10 VDC. e) SBS part number IP-OptoDA16-4CH (quantity 33), Industry pack that provides 4 channels of optically isolated 16 bit analog outputs. f) SBS part number IP-488 (quantity 3), Industry pack for interfacing with IEEE-488 instrumentation. No other source is known for these parts that meet all of our requirements. These parts have been designed into the antenna IF/LO and MRG control assemblies. The carrier boards are unique in the industry in that they provide superior EMI shielding and interface via four SCSI-2 connectors. The industry packs have been tested and meet all of the Submillimeter Array specifications. Cables and hardware have been designed to accommodate the pinouts of these parts. Software and software drivers have been written to control the SBS line of industry packs and industry pack carriers. The desired delivery date for the required items is 17 April 2000. The FOB point is destination, Cambridge, MA. This acquisition will be accomplished using simplified acquisition procedures in accordance with the Federal Acquisition Regulation Part 13. The applicable SIC code is 3674 and the size standard is 500. No solicitation package will be issued. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. A determination by SAO to not compete this effort on a full and open competitive basis, based upon responses to this notice, is solely within the discretion of SAO.
