The Keysight N1092E DCA-M is a sampling oscilloscope built for high-speed optical and electrical signal characterization. It combines two optical channels and two electrical channels in a compact form factor, delivering >40 GHz optical bandwidth (with Option 40A) and 50 GHz electrical bandwidth for accurate waveform acquisition across 8.4 to 64 Gbaud data rates. Sub-200 fs jitter performance enables precise timing analysis on high-speed serial links.
