Solving the need for speed… Without breaking your
budget
Verifying 100G ethernet or 16GFC transceivers requires a BERT operating beyond 13G.
This often results in multiple designers needing to share the one serial BERT in the lab—
delaying their characterization, along with the development schedule.
The N4960A BERT has fast transition times and real time BER count updates. In addition,
low intrinsic jitter provides continuously settable clock frequencies allowing data rates
from 5 to 32 Gb/s rates and from 4 to 17 Gb/s. As a result, high quality signals produce
excellent fidelity in the eye for improved measurement accuracy.
The solution is compact—allowing it to be easily transported throughout the lab and
manufacturing.
Compact architecture
The N4960A serial BERT system consists of the N4960A clock source/controller plus re-
mote pattern generator (N4951A/B) and error detector (N4952A) heads. The controller can
operate as a stand alone clock source, with jitter injection, in addition to providing the pre-
cision timing and control required for remote pattern generator and error detector heads.
Place signal close to DUT
The concept of remote heads, first introduced with the N4965A multi-channel BERT
controller, puts the pattern generation and error detection near the device under test,
eliminating long cables which degrade the signal. This is especially important beyond
17 Gb/s.
