The 3000T X and 4000X share the same core specs (4 Mpts memory, 5 GSa/s, 1M wfms/s update rate) but target different professional use cases. The 4000X wins on display size — 12.1-inch capacitive touch screen versus 8.5-inch on the 3000T — making it significantly more comfortable for extended use and multi-signal analysis. The 4000X also adds InfiniiScan advanced triggering for complex signal anomalies. At matching bandwidth (350 MHz), the 4000X justifies its higher price primarily through the larger display and InfiniiScan triggering, not raw performance.
