N4874A - Agilent HP Bit Error Rate Testers

The Agilent ParBERT 7 Gb/s modules are the ideal solution for testing high-speed communication ports, chips and other serial or multiple-serial interfaces for a broad range of applications such as the emerging backplane, memory interface and serial bus applications working up to 6.4 Gb/s.

The Agilent N4874A 7 Gb/s generator module and N4875A 7 Gb/s analyzer module is each one VXI slot wide and requires the E4809A Central Clock module.
The ParBERT 7 Gb/s modules are able to generate and analyze differential or single-ended signals at data rates from 620 Mb/s to 7Gb/s.
