Available with 1, 2, and 4 optical channels, respectively, N1092A, N1092B, and N1092D DCA-M Sampling Oscilloscopes feature low-noise, low-jitter technology, which allows measurement of low-power, high data rate NRZ and PAM-4 devices that could not be performed with other solutions. Channels have calibrated reference receivers for industry-standard compliance test from 20–28 Gbps rates and are compatible with single-mode and multimode fibers and wavelengths.
