The HD3 is Keysight's high-definition oscilloscope line, built around a 14-bit ADC — delivering 64× better vertical resolution than the 1000X's 8-bit ADC. This makes the HD3 uniquely suited for precision power electronics, noise floor analysis, and subtle signal anomaly detection where conventional 8-bit scopes fall short. Its 50 Mpts memory depth (50× the 1000X) enables long captures at high sample rates. The Frequency Response Analysis (FRA) feature for Bode plots is absent on the 1000X. The 1000X is an entry-level scope; the HD3 is a specialized precision instrument for power and signal integrity engineers.
