Microwave digital lock-in amplifier

The National Institute of Standards and Technology (NIST) Physical Measurement Laboratory is seeking to procure a single microwave digital lock-in amplifier for its Photonics and Optomechanics Group under solicitation number 1333ND25QNB680416. The instrument must operate at frequencies of at least 1.8 GHz and be capable of measuring amplitude and phase of signals at multiple frequencies and their harmonics simultaneously to support semiconductor supply chain metrology and integrated photonics research. Key technical requirements include two independent lock-in channels, DC to 1.8 GHz frequency range, 14-bit ADC resolution, USB 3.0 and Gigabit Ethernet interfaces, and Windows 11 compatible software. The procurement will be conducted as a full and open competition using simplified acquisition procedures, with evaluation based on a best value trade-off approach where Technical Capability serves as the primary factor and Price as the secondary factor. Offerors must submit electronic quotations via email by August 20, 2025, divided into three volumes covering technical quotation, price quotation, and terms and conditions.

This opportunity does not utilize any set-aside designations and will be conducted under NAICS code 334516 (Analytical Laboratory Instrument Manufacturing) with a small business size standard of 1,000 employees. No incumbent contractors or potential award values are specified in the solicitation documents. The contractor must deliver a new, commercial off-the-shelf instrument within four months of award, with experimental, prototype, or "gray market" components being unacceptable. Performance will occur at NIST's facility in Gaithersburg, Maryland, where the equipment will undergo performance testing and visual inspection before acceptance. The contractor must provide a minimum 12-month warranty covering all parts and labor, with payment of 100% due upon acceptance by the NIST Point of Contact. Offerors must be registered in the System for Award Management (SAM) and provide detailed technical documentation demonstrating compliance with all specified requirements.
