PRBS Generators

The Keysight Technologies family of PRBS generators provides the generation of high fidelity pseudo-random binary sequence (2n-1 format) data signals for testing high speed communications components. These low cost, compact generators cover a frequency range from 50 Mb/s to 56 Gb/s, with amplitudes up to 1.6 V pp differential and low jitter, fast rise/fall times. The PRBS generators combined with a DCA wideband sampling oscilloscope allow easy stimulus-response testing of components such as driver amplifiers, optical modulators, cable & backplane testing for 100GbE, 10GbE, 10/40G SONET/SDH, 8G/16G FC, OIF-CEI 25/28/56G applications.
