NIST-SS25-26 Title:? Terminal Guarded Coaxial Scanner BACKGROUND The National Institute of Standards and Technology (NIST), Physical Measurements Laboratory (PML), Fundamental Electrical Measurement (... NIST-SS25-26 Title:? Terminal Guarded Coaxial Scanner BACKGROUND The National Institute of Standards and Technology (NIST), Physical Measurements Laboratory (PML), Fundamental Electrical Measurement (FEM) group realizes and maintains the units of resistance, capacitance, and inductance for the United States. To support and verify the automated connection of resistance standards at dc requires guarded coaxial switching of four-terminal standards, including the shields of the connections. In order to meet the mission indicated above, FEM requires instruments to automate the connection of four-terminal electrical resistance standards to measurement systems such as resistance bridges and cryogenic current comparators. Measurements will be made using artifact standards and graphene quantum Hall array resistance standards (QHARS) with low uncertainty traceable to fundamental constants. Guarded coaxial connections provide a solution to electrical/thermal noise errors associated with leakage currents to ground that can effect high accuracy electrical measurements at parts in 10-7 to 10-8 uncertainty level. NIST is seeking information from sources that may be capable of providing a commercial item solution that meets or exceeds the following draft minimum specifications, inclusive of FOB Destination shipping and warranty: Line Item 0001: Description: Terminal Guarded Scanners Quantity: Four (4) Technical Specifications Grinder/Polisher Electro-mechanically connect four-wire input signal pairs (High and Low), where each pair has 2 insulated center conductors and a shield to one of 10 to 16 output channels (High and Low), where each pair has 2 insulated center conductors and a shield. The scanner must provide for the connection of four-terminal guarded standard resistor to four-terminal guarded resistance bridges is needed, where the center conductors and associated shields which are connected with the selection of a channel. Each channel has a pair of High and Low set of leads, with separate and isolated shields switched. High and Low shields must be isolated from each other. The guarded shields surround the pairs of conductors and can be driven at a guard potential, up to 1000 volts. Shall be remotely programmable through IEEE-488 (GPIB) interface as well as operated from front panel. Shall have guarded coaxial connections for input and output terminals with all shields isolated from the instrument chassis and other input/output shields, allowing the shields to be driven at guard potential. Guarded cable lengths shall not exceed six (6) feet. One (1) pair of input cables, sixteen (16) pairs of output cables. Each cable has 2 conductor stranded copper with Polyethylene (PE) insulation, surrounded by braided guard shield with insulation outside. Alternatively, termination of guarded cables may be on the back panel using pairs of coaxial connectors (BNC, N-type, or BPO) for each cable with all connector shields isolated from the instrument chassis and each other. The pairs of connectors shields must be connected only to the shield of the input/output cable. Contact life greater than 10,000,000 cycles. Leakage resistance greater than 1 x 1012 ? without the guard circuit energized. Shall include hardware for mounting in nineteen (19) inch instrument rack. Shall provide a minimum one (1) year warranty HOW TO RESPOND TO THIS NOTICE In responding to this notice, please DO NOT PROVIDE PROPRIETARY INFORRMATION.
