Lock-In Amplifier for Laser Doppler Vibrometer (LDV) System

The National Institute of Standards and Technology (NIST) is soliciting quotations for a Lock-In Amplifier and Arbitrary Waveform Generator to support the RF Technology Division's CHIPS R&D Metrology Program, specifically for electro-acoustic metrology of piezoelectric materials for wireless communications. The lock-in amplifier must analyze signals up to 600 MHz with at least two channels capable of demodulating eight harmonic signals, while the arbitrary waveform generator must feature a minimum 2.4 GSa/s sampling rate with at least four channels and 250 MHz bandwidth. Quotations will be evaluated primarily on technical capability—including specifications compliance, delivery schedule performance, and installation timelines—with price evaluated for fairness and reasonableness but not scored competitively. Questions regarding the solicitation must be submitted by April 27, 2026 at 10:00 AM ET, with quotations due electronically by May 5, 2026 at 10:00 AM ET; quotations must remain valid for a minimum of 90 calendar days. The Government intends to award without discussions but reserves the right to conduct discussions if necessary.

This is an unrestricted procurement with no small business set-aside, classified under NAICS 334515 with a small business size standard of 750 employees. The contract will be issued as a Firm-Fixed Price Purchase Order with delivery required within four months after receipt of order on a FOB Destination basis to NIST's Shipping and Receiving department in Boulder, Colorado. One lock-in amplifier unit and one arbitrary waveform generator unit are being procured, with payment at 100% upon installation, acceptance, successful testing, and demonstration of performance compliance. The contractor must provide a system warranty covering parts and labor commencing upon government acceptance, and must be available to assist in troubleshooting within three business days of notification of any issues. No incumbent contractor information or specific award value has been disclosed in the solicitation materials.
