LinkIQ vs DSX: qualifier or certifier?
Short answer: if a manufacturer warranty or the spec calls for certification to TIA/ISO limits, you need a certifier like the DSX. LinkIQ is a qualifier: it tells you whether a link will carry a given speed (up to 10 Gb/s) and helps troubleshoot PoE and switch ports, but it doesn't produce the Level V/VI certification reports that 25-year manufacturer warranty programs (CommScope, Panduit, Corning and others) typically require.
Price gap: the LinkIQ kit lists from about $2,950 new, against roughly $13,400–$16,600 for a new DSX2-5000 or DSX2-8000. A used Versiv-1 DSX-5000 can be found from about $3,000 to $8,500, which is LinkIQ money for certification capability. Just check the calibration date and that it's on a firmware LinkWare still supports.
Rule of thumb: service techs and in-house IT do fine with LinkIQ. Installers who hand over warranty documentation need a DSX (or a Softing WireXpert / AEM TestPro / VIAVI Certifier40G), and if certification jobs are rare, renting one is often the cheapest route.
