Description

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:

Description: Terminal Guarded Scanners

Quantity: Four (4)

Technical SpecificationsGrinder/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 ...
