What the notice says

BACKGROUND The National Institute of Standards and Technology (NIST) provides a calibration service for power and energy meters to provide traceability for the over $400 billion annual sales of electricity in the US. Wideband power sensors are needed to modernize the NIST RF AC-DC measurement services and reduce calibration uncertainties at high frequencies associated with impedance mismatch effects. The National Institute of Standards and Technology (NIST) has a requirement for 2 balance thermocouple sensor and is seeking information from sources that may be capable of providing a solution th… (show all)
