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, a Commodity code, does not reflect the work actually being solicited under this code in recent state and local procurement. The recent opportunities dataset shows no audio spectrum analyzers; instead, the code appears in solicitations that are entirely unrelated to the commodity's nominal scope—specifically, orders for classroom projectors, LED video walls, comprehensive AV systems integration and maintenance, concert hall audio renovations, assisted listening systems, and general audiovisual equipment and services spanning design, installation, support, and live event production. State and local procurement offices have tagged a broad range of AV integration and support work under this Commodity code despite the code's narrow definition.

The issuing bodies span school districts (Northside ISD in San Antonio, Cobb County Schools, Clarke County Schools, Jones County Schools, Walled Lake Consolidated Schools, Hillsborough County Public Schools, DeKalb County Schools), cities (Arlington, Santa Monica, Orlando, St. Marys, New Haven, College Park), counties (Gwinnett, Monroe, Wake, Volusia), higher education (University of Texas at Austin, Valencia College, University of Wisconsin–Green Bay, University of Texas at Tyler), and special-purpose authorities (Railroad Commission of Texas, Atlanta Regional Commission, Texas A&M University System). Recent activity concentrates in Texas, Georgia, Florida, and Michigan, with scattered opportunities in California, Colorado, Oregon, Washington, and elsewhere. The code shows strong recent activity—multiple solicitations posted in July 2026 alone, including Northside ISD's indefinite quantity contract for classroom projectors and AV services (RFP2026072, due Aug 6, 2026), the City of Arlington's LED walls procurement for Council Chambers (Solicitation 260265, due Aug 20, 2026), and the City of Santa Monica's five-year AV systems integration RFP (2026RFP00034, due Aug 3, 2026 with prevailing wage and California contractor licensing requirements). The code also covers event production work such as the Railroad Commission of Texas's live broadcasting IFB for annual meetings (IFB #455-26-1030, due Jul 15, 2026) and DeKalb County Schools' district-wide graduation audio-visual services RFP (RFP 26-728, due Feb 26, 2026). Given the mismatch between the code name and actual procurement scope, vendors should disregard the "audio spectrum analyzer" definition and instead track opportunities under this code as broad AV system integration, maintenance, support, and event production services targeted at government facilities, educational institutions, and public assembly spaces.
