Precision Shaker Spectrometer BACKGROUND The Physical Measurement Laboratory at NIST develops advanced sensors to measure acceleration. As part of this work a shaker (also called a vibrational exciter system) is required to test photonic accelerometers. The shaker will operate vertically and include an internal reference accelerometer. The system will include the shaker, the amplifier to run it, the internal reference accelerometer, and the signal conditioning electronics to read it, as well as all cables and accessories required to operate the system with an accelerometer mounted. The system shall meet or exceed the minimum requirements identified below. All items must be new. Used or remanufactured equipment will not be considered for award. Experimental, prototype, or custom items will not be considered. The use of “gray market” components not authorized for sale in the U.S. by the Contractor is not acceptable. All line items shall be shipped in the original manufacturer’s packaging and include all original documentation and software, when applicable. One (1) shaker One (1) amplifier and other electronics and accessories to run the shaker, including cables. One (1) internal reference accelerometer Signal conditioning electronics and other accessories to read the accelerometer, including cables The contractor shall provide the shaker and internal reference accelerometer in accordance with the technical specifications listed below: Contract Line Item Number (CLIN) 0001 Minimum technical specifications for the shaker Quantity: One (1) Vertical operation Maximum payload of at least 1000 grams Frequency range of at least 5 Hz to 15 kHz for frequency response measurements. Able to supply an acceleration with a 150 gram load of at least 100 m/s2 over the frequency range of 30 Hz to 10 kHz continuously for 5 minutes. First resonance > 50 kHz Transverse motion less than 3% between 5 kHz and 15 kHz. Shaker Dimensions: requires less than 1 square foot table space and less than 6” height, shaker weight less than 20 kg A calibration certificate traceable to NIST for operation between 5Hz and 20 kHz with no load. No requirement for water or pneumatic supply. Base plate modified to mount on table with 1” spacing between holes. Standard hole diameter is adequate. Contract Line Item Number (CLIN) 0001 Minimum technical specifications for the reference accelerometer Quantity: One (1) Mounted internally to shaker Sensitivity >= 1 mV/(m/s2) Freq range (3dB) greater than 3 Hz to 30 kHz Resonant frequency greater than 50 kHz Deviation from linearity less than 1% HOW TO RESPOND TO THIS NOTICE In responding to this notice, please DO NOT PROVIDE PROPRIETARY INFORMATION. Please include only the following information, readable in either Microsoft Word 365, Microsoft Excel 365, or .pdf format, in the response. Submit the response by email to the Primary Point of Contact and, if specified, to the Secondary Point of Contact listed at the bottom of this notice as soon as possible, and preferably before the closing date and time of this notice. Provide the complete name of your company, address, name of contact for follow-up questions, their email, their phone number and, if your company has an active registration in https://sam.gov, your company’s Unique Entity ID (UEI). Details about what your company is capable of providing that meets or exceeds NIST’s minimum requirements. Whether your company is an authorized reseller of the product or service being cited and evidence of such authorization. Identify any aspects of the description of the requirements in the BACKGROUND section above that could be viewed as unduly restrictive or create unnecessary barriers that adversely affect your firm’s ability to fully participate in a procurement for such services and explain why. Please offer suggestions for how the requirements could be organized or structured to encourage the participation of small businesses. For the NAICS code Indicate whether your company is (a) a small business or (b) other than small business. See the Table of Small Business Size Standards and the associated .pdf download file for small business size standards and additional information. If you believe the NAICS code listed in this notice is not the best NAICS code for the type of product addressed in this notice, identify an alternative NAICS code that you believe would be more appropriate for the planned procurement. If your firm has existing Federal Supply Schedule contract(s) or other contracts for products or services against which the Department may be able to place orders, identify the contract number(s) and other relevant information. Describe your firm’s experience (as a prime, subcontractor, or consultant) providing the products or services described in Background section. Provide any other information that you believe would be valuable for the Government to know as part of its market research for this requirement. Please let us know if you would like to engage to get a better understanding of the requirement or need additional information about the Government’s requirement for the products or services described in the Background section.
