The Keysight (Agilent) 81130A is a precision Pulse Data Generator mainframe offering advanced delay and width accuracy driven by a high-stability PLL oscillator. It provides robust pattern generation capabilities, including segmentable memory, sequenced PRBS, and complex loop structures for digital device testing and data communication applications. The mainframe requires one or two specific output modules (81131A or 81132A) to function, dictating the maximum frequency, transition times, and output voltage.
