Keysight / Agilent / HP E8305A 250 MHz Pulse Pattern Generator

The Keysight/Agilent/HP E8305A is a 250 MHz Pulse Pattern Generator housed in a VXI C-size, single-slot module for integration into VXI mainframe systems. This dual-channel instrument delivers precise pulse parameter control across a 1 mHz to 250 MHz frequency range, making it suitable for high-speed digital circuit characterization, signal integrity analysis, and component testing across TTL, CMOS, ECL, PECL, LVDS, and GTL logic technologies.
