Key Features & Specifications

Electrical modules:

  • Bit rates of 21 Mb/s up to 3.35 Gb/s
  • Differential or single-ended data output and input
  • Jitter injection via 500 ps delay line
  • 16 Mbit memory depth per channel


Keysight’s 3.35 Gb/s modules for ParBERT 81250 are perfect to measure gigabit devices of standards like PCIe, SATA or 10GbE.

Low intrinsic jitter, superior signal performance and a 500 ps delay line for jitter injection provide in-depth and accurate characterization.
