The serial BERT N4906B is a general-purpose bit error ratio tester,

designed for testing high-speed digital communication components and

systems. It is ideal for cost-effective manufacturing and telecom device

testing. It offers a 3.6 or 12.5 Gb/s pattern generator and error detector

with excellent price/performance ratio.

Transition times < 25 ps allow precise measurements. The analyzer can be

configured with CDR to test clockless interfaces and with true differential

inputs to test LVDS and other differential interfaces.

interfaces allow smooth integration into automated test environments.

For bench users the N4906B serial BERT offers an intuitive user interface

with state-of-the-art Windows-XP based touch-screen.

Deeper insight into the device’s performance can be obtained with the

enhanced measurement suite. It offers many valuable signal analysis

tools, such as BERT scan (so-called bathtub curves) with total jitter and

its separation into RJ and DJ, eye contours, spectral jitter decomposition

and more.
