The Keysight N1092E is a DCA-M sampling oscilloscope purpose-built for high-performance optical and electrical waveform analysis in communication system applications. It integrates two optical and two electrical channels on a compact platform, enabling simultaneous multi-signal measurement with low noise and high accuracy. The instrument combines the advanced acquisition architecture of the DCA-X with specialized 861XX series channel hardware, delivering precise signal characterization from 1.25 Gb/s through 64 GBaud with sub-200 fs jitter performance.
