The 2000X and HD3 share the same maximum bandwidth (200 MHz) but serve different measurement philosophies. The HD3's 14-bit ADC provides 64× better vertical resolution — ideal for measuring small signal variations, power supply ripple, and noise floor characterization. Its 50 Mpts memory depth (50× the 2000X) enables extremely long captures at full sample rate. Both support MSO, but the HD3 offers up to 16 digital channels vs 8 on the 2000X. The 2000X is a strong general-purpose 4-channel scope; the HD3 is the choice when measurement precision and long capture depth are more important than bandwidth.
