UNSPSC 45111720: Audio spectrum analyzer

Equipment that is designed to find out the size or characteristics of signal by analyzing for each frequency of the signal output through various audio devices.

UNSPSC 45111720 Audio spectrum analyzer (Commodity) covers equipment and integrated system procurement for audio-visual infrastructure—including speakers, microphones, signal processors, cameras, displays, control systems, and related installation and support services—that state and local governments deploy across civic chambers, courtrooms, educational facilities, event venues, and emergency operations centers. Recent solicitations show state and local buyers purchasing turnkey AV system upgrades, not standalone spectrum analyzers; the code's nominal scope does not align with what is actually being procured under this classification. The work spans design, procurement, installation, programming, testing, training, and ongoing maintenance across multiple facility types and geographic regions, with vendors typically required to hold factory certifications, provide references from comparable projects, and maintain comprehensive insurance and warranty coverage.

Cities, counties, school districts, and special-purpose authorities dominate the issuing-body mix. The City of Holly Hill, Florida solicited a comprehensive Commission Chambers A/V upgrade (RFP 26PW01, proposals due February 11, 2026) including wireless microphones, ceiling speakers, digital signal processors, amplifiers, cameras, and sound bars. Fort Bend Independent School District requested athletics A/V equipment and related services (RFP 27011RA, proposals due November 16, 2026). Volusia County sought an integrated Emergency Operations Center system upgrade with A/V and IT components (RFP 26-P-33JRD, proposals due January 29, 2026). The City of Dahlonega, Georgia and Collin County, Texas each issued RFPs for courtroom and council chamber AV refreshes. The Georgia World Congress Center Authority solicited preferred-provider audio-visual and production rigging services (RFP, proposals due September 30, 2026). The City of Santa Monica issued a five-year citywide AV systems integration and maintenance contract (RFP 2026RFP00034, proposals due August 3, 2026), and City Colleges of Chicago sought AV modernization across over 500 multimedia classrooms (RFP NC2621, proposals due September 8, 2026). Texas Procurement and Support Services (TIPS) established a cooperative purchasing vehicle for AV equipment and services statewide (RFP 260901, proposals due October 16, 2026). Recent activity concentrates in Florida, Georgia, Texas, Michigan, Colorado, Illinois, and California, with school districts and municipal governments as repeat buyers across all regions. Prospective vendors should note that the code shows significant recent activity but encompasses integrated system procurement far broader than spectrum analysis; submissions should focus on full-scope AV system design, installation, and support capabilities rather than measurement or diagnostic instruments.
