Amendment to Lock-In Amplifier

The contract pertains to Amendment 1 to a solicitation for a Lock-in Amplifier and an Arbitrary Waveform Generator, issued by the National Institute of Standards and Technology (NIST) under solicitation number 1333ND26QNB030183. The procurement requires the delivery of two key instruments: a Lock-in Amplifier with the UHF-MF Multi-frequency Option to enable demodulation of eight harmonics from a single reference signal, which is a mandatory technical requirement, and an Arbitrary Waveform Generator with a minimum sample rate of 2.4 GSa/s, four channels, a bandwidth of at least 250 MHz, and a peak output of 5 volts. The contract is structured as a firm-fixed-price quotation with a period of performance of approximately 12 weeks, culminating in delivery F.O.B. Destination (DDP) to NIST’s facility at 325 Broadway, Boulder, Colorado, with formal acceptance to occur on-site. The response deadline has been extended to May 8, 2026, and quotations must be submitted electronically via email to designated NIST contacts with the solicitation number included in the subject line. Proposals must be organized into three volumes: technical documentation demonstrating compliance with all minimum requirements, a separate firm-fixed-price breakdown valid for 90 days, and a terms and conditions response accepting or objecting to all clauses. All proposals are subject to a Lowest Price, Technically Acceptable (LPTA) evaluation process, where technical acceptability is assessed on a pass/fail basis based on meeting every requirement in the Statement of Work; failure to meet even one requirement results in disqualification, after which the lowest priced acceptable offer is selected. The contract enforces strict compliance with federal cybersecurity standards including FISMA, OMB A-130, FIPS 200, and NIST SP 800-171, requiring a System Security Plan and restricted access to sensitive information. Contractors must also adhere to federal procurement integrity laws, anti-kickback statutes, and prohibitions on transactions involving Iran’s IRGC. Invoicing must be submitted exclusively through the Treasury’s Invoice Processing Platform (IPP), and delivery must meet carrier marking requirements including the entity name, CAGE code, and manufacturer code, with no specific packaging or preservation standards beyond carrier compliance. A one-year warranty is required from the date of government acceptance, covering repair, replacement, and return shipping costs. The
