PULSE PATTERN GENERATORS/ERROR DETECTORS

ERROR DETECTOR

MP1776A

100 MHz to 12.5 GHz

Supports Measurement for up to 50 Gbit/s System (Installed with 4 Channels)

MP1776A is an error detector housing four error detectors that canmeasure error up to 12.5 Gbit/s. It has four-channels independent measurement mode, two-channels or four-channels combined mea- surement mode and be used for development, manufacturing and maintenance of transmission systems and modules from 12.5 Gbit/s to maximum 50 Gbit/s.
