The Naval Air Warfare Center Weapons Division in China Lake, CA intends to sole source the procurement of one Spectrum Analyzer & Assembly to Bristol Instruments, Inc. This is because their specific 771A-MIR model is identified as the only analyzer meeting all critical technical requirements. While not a request for competitive proposals, any firm believing it can fulfill the requirement may submit a capability statement via email for agency consideration within 5 days of the notice's publication. All responsible sources must have an active registration in the System for Award Management (SAM), which now requires a notarized letter for registration or renewal. It is recommended interested parties proactively manage their SAM status to avoid processing delays.
