The National Institute of Standards and Technology (NIST) is conducting market research to identify vendors capable of supplying a Vector Signal Generator, as detailed in the attached specifications. This is a sources sought notice for information-gathering purposes only, not a request for quotes, and does not commit the government to a future award. The government will use responses to determine if a small business set-aside is possible, but all responsible sources, including large and small businesses, are encouraged to respond. No budget information, performance location, or submission timelines are specified in this notice. Interested firms should submit a capability statement of five pages or less, including company profile, product details, and lead time.
