High-accuracy scopes target 25/100/400 Gb/s optical testing

Networks of 100 and 400 Gb/s rely on multiple-lane transmitters based on 25 Gb/s class lasers. As these technologies become mainstream and transition to high-volume manufacturing, there is a growing need for test systems that provide high accuracy at a low cost.
                                                                                               
The N1092X DCA-M is a sampling oscilloscope family designed specifically to perform compliance tests quickly and accurately. New low-noise, low-jitter technology allows measurement of low-power, high data rate NRZ and PAM-4 devices that could not be performed with any other system. The FlexDCA user interface on the N1092X oscilloscopes is identical to that used in the industry-standard 86100D DCA-X sampling oscilloscope, allowing a drop-in replacement for existing test systems, but with substantially faster throughput, a much smaller footprint and more than double the sensitivity.

The N1092X Series is available in three model numbers to fit a variety of applications and budgets. The N1092A has one optical channel, the N1092B has two optical channels and the N1092D has four optical channels. Channels have calibrated reference receivers for industry-standard compliance test from 20 to 28 Gb/s rates and are compatible with single-mode and multimode fibers and wavelengths. The costs of the oscilloscopes claim to be approximately half of existing systems with comparable performance.
