The 4000X and 6000X are separated by a massive performance gap. The 6000X delivers up to 6 GHz bandwidth and 20 GSa/s sample rate — four times faster than the 4000X's 5 GSa/s — making it essential for high-speed serial data, DDR, and RF characterization at GHz frequencies. The 6000X also features a 10-bit ADC versus 8-bit on the 4000X, providing 4x better vertical resolution for precision measurements. The trade-off is update rate: 450k vs 1M wfms/s on the 4000X. Both share the 12.1-inch touch screen and identical memory depth. The 6000X is the choice for high-frequency RF and high-speed digital work; the 4000X covers most general-purpose and mid-frequency needs at a significantly lower price.
