The Keysight / Agilent 81110A is a versatile single- or dual-channel Pulse Pattern Generator mainframe capable of operation up to 330 MHz. It requires one or two output modules to function, natively supporting the 81111A (165 MHz, 10 V, single-ended) and the 81112A (330 MHz, 3.8 V, differential) modules. Designed to replace the industry-standard 8110A, it offers selectable pulse, burst, and pattern modes, PLL capability, and a self-calibration feature that significantly improves timing accuracy.
