The 6000X and HD3 are both premium instruments that excel in different domains. The 6000X dominates on bandwidth (1 GHz, upgradeable to 6 GHz) and sample rate (20 GSa/s) — essential for RF, DDR, and high-speed serial work. The HD3 focuses on measurement precision: its 14-bit ADC provides 16× better vertical resolution than the 6000X's 10-bit ADC, and its 50 Mpts memory (12.5×) enables extremely long high-resolution captures. The HD3 also adds MSO capability and FRA for power supply analysis. Both feature touch screens. The 6000X is the high-frequency specialist; the HD3 is the high-resolution precision specialist.
