The Keysight N1092D is a four-channel optical sampling oscilloscope engineered for high-speed optical communication signal characterization. It delivers sub-200 fs jitter performance and operates across 830 nm to 1600 nm wavelengths, supporting data rates from 20 to 28 Gb/s and modulation formats including NRZ and PAM4. The instrument integrates standard reference receivers for 25 Gb Ethernet, 400 Gb Ethernet, OTU4, and Fibre Channel applications, with optional bandwidth expansion to >40 GHz and advanced filtering configurations.
