58 -- RANGE SPECTRUM MANAGEMENT SYSTEM SOL N00178-97-Q-3008 POC Maryann Piersall, (540)653-7765; J. E. Thomson. The Naval Surface Warfare Center, Dahlgren Division is seeking sources for commercial-off-the-shelf (COTS) spectrum management equipment. Both a mobile and a fixed site are being considered. Both sites must be capable of performing the following functions: (1) Monitor communications frequencies (10 KHz to 2 GHz AM, FM, and WFM), and automatically record and time tag activity with WWV time data; (2) Display and provide hard copies of amplitude vs frequency plots for any desired portion of the spectrum between 10 KHz and 40 Ghz. The amplitude vs frequency plots described here must include the start/stop frequency, power reference level, dB/division, time of day, date, and a movable marker with center frequency and power level indications; (3) Make pulse repetition frequency (PRF) measurements for 500 MHz to 40 Ghz; (4) Measure percent modulation, FM deviation, frequency bandwidth and center frequency for 10 KHz to 40 Ghz; (5) Make calibrated power measurements for 10 KHz to 40 Ghz; and (6) Provide direction finding capability for 10 KHz to 40 GHz with a bearing accuracy of +/- 2 degrees for a 8 dB signal to noise ratio. HF-SSB, VHF-FM, and UHF transceivers are required for the fixed site and a VHF-FM transceiver is required for the mobile site. The mobile site must include the necessary equipment to measure and plot electric field intensity on a power vs frequency graph as described in MIL-STD-461D RE102 and RE103. All proposed fixed site equipment should be capable of being controlled by an external computer terminal via a standard interface such as IEEE-488. Fixed site equipment which has COTS control software available for Windows is desirable. Windows 32 bit control software is highly desirable. It is requested that offerors submit high level data sheets for all proposed subsystems. A block diagram (one each for the mobile and fixed site) showing signal distribution and subsystem interconnection would also be helpful. A cover sheet which associates the proposed subsystems with the requirements met is required. It is also requested that offerors provide a non-binding, rough order of magnitude (ROM) cost estimate for their proposed equipment. Offerors who cannot meet all the requirements can submit a data package and ROM which addresses only a portion of the requirements so long as the requirements met and the requirements not met are clearly identified on the cover sheet. This is not a request for proposal nor does the Government intend to pay for the requested information. Submit responses no later than 6 December 1996 to: Contracting Officer, Attn: SD13/Maryann Piersall, Naval Surface Warfare Center, 17320 Dahlgren Road, Dahlgren, Virginia 22448-5100.
