The Keysight N1092B is a dual-channel optical sampling oscilloscope module designed for signal integrity and compliance measurements in high-speed optical and digital communication systems. It delivers time-domain and frequency-domain analysis, jitter measurement, eye diagram acquisition, and impedance characterization across data rates from 20 to 28 Gb/s with optional extensions to 64 GBaud. The module integrates specialized optical channel hardware with high-performance acquisition elements, enabling accurate transmitter compliance verification in manufacturing and R&D environments. Control is provided through a user PC running N1010A FlexDCA software, which maintains an interface consistent with modern DCA platforms.
