Keysight Balance Thermocouple Power Sensors

The National Institute of Standards and Technology seeks Keysight balance thermocouple power sensors for its Applied Electrical Metrology group, with quotations due September 2, 2026, and pre-quote inquiries due within five calendar days of solicitation issuance. This is a brand name–only acquisition; market research documents that only Keysight products meet the required cooling capacity and temperature specifications.

Place of performance and delivery destination is NIST Gaithersburg, Maryland (100 Bureau Drive, Building 220, Room B153, Gaithersburg, MD 20899-8172). The procurement includes two Keysight N8481S balance thermocouple sensors for DC to 18 GHz applications with N-type connectors, one Keysight N8487S sensor for DC to 50 GHz applications with 2.4 mm connectors, and one Keysight N8480SBSA software application with perpetual licensing and USB Windows 11 compatibility. Both sensor types must deliver calibration with factor uncertainty not exceeding 1.75 percent at their respective highest frequencies, support null arrangements with two thermoelements, and handle power ranges from −35 to +20 dBm (CW +25 dBm, modulated pulse +42 dBm). All items must be new, factory-sealed in original manufacturer packaging with complete documentation. Delivery is FOB Destination within 60 days after receipt of order.

The NAICS code is 334516 (Analytical Laboratory Instrument Manufacturing) with a small business size standard of 1,000 employees. Awards will be made to the lowest priced, technically acceptable offeror on a firm-fixed-price basis under simplified acquisition procedures. Quotations must include three volumes: Technical (demonstrating equipment meets all minimum requirements), Price (FOB Destination, valid 90 days), and Terms and Conditions (acceptance or exceptions). All vendors must maintain active SAM.gov registration at quotation submission and through final payment. The Government reserves the right to reject and obtain replacement or repair at contractor expense; payment is Net 30 upon 100 percent acceptance and successful NIST testing verification.
