The details
Short answer: there's no single best certifier. It depends on whether you need Cat 6A or Cat 8 and how often you certify. For Cat 6A warranty work, the Fluke DSX2-5000 is the safe default. For Cat 8 for less money, look at the Softing WireXpert 4500 or AEM TestPro CV100. If you only certify a few jobs a year, rent (DSX-5000 from $475/week).
Cheaper Cat 6A routes: a used Versiv-1 DSX-5000 was $3,000–$8,497 (see is a used DSX-5000 worth it?). The DSX-602 was $9,999.95 new or $7,799 refurbished, and its listing notes it can be upgraded to DSX-5000 functionality. The 500 MHz Softing WireXpert 500 was $7,400–$8,915.55 new in the US.
Don't need certification? A qualifier like the LinkIQ is a different tool. See LinkIQ vs DSX.
