The Keysight N1092D DCA-M is a quad-channel sampling oscilloscope engineered for high-speed optical signal characterization and analysis. This instrument delivers simultaneous measurement across four optical channels with noise as low as 5 µW and jitter below 200 fs, enabling precise signal integrity assessment for optical transceivers, components, and systems operating at data rates from 20 Gb/s through 53 GBaud.
