Keysight / Agilent / HP E1428A 1 GSa/s VXI Oscilloscope

The Keysight E1428A is a single-slot C-size VXIbus oscilloscope module engineered for high-speed signal acquisition in automated test systems. Operating at 1 GSa/s with 8-bit vertical resolution, it captures transient phenomena with superior timing accuracy and configurable memory depth up to 32,768 points per channel. The module integrates dual analog channels with 100 MHz bandwidth, switchable 1 MΩ / 50 Ω input impedance, and five distinct trigger modes

Edge, Pulse Width, Pattern, State, and Line. Its ±25 ppm timebase accuracy and <100 ps RMS trigger jitter support precision measurement in complex signal environments. VXIplug&play compatible architecture enables rapid integration into existing mainframe systems and software stacks.
