4 -- 17 Gb/s Programmable Stressed BERT Solution

Product Fact Sheets

 Fast, compact, and affordable BER testing

Testing 16x fibre channel (16GFC) transceivers requires equipment capable of 14 Gb/s and accurate characterization to strict tolerances. Until now, these systems have been extremely expensive. This often results in multiple designers needing to share the one serial BERT in the lab, delaying their characterization and development schedule.

The Keysight Technologies, Inc. N4960A serial BERT 17 Gb/s is an affordable alternative for R&D working at data rates up to 17 Gb/s. In fact, it’s even affordable for manufacturing test.

The solution is compact, allowing it to be easily transported throughout the lab and manufacturing. But with its low price, a fraction of competing stressed BERTs, you can afford to put one on each bench.

Integrated analysis software

Support for both models of the N4960A (SSB16000) is included in the N4980A multi-instrument BERT software (Signal Integrity Studio). The base software provides an intuitive user interface. It also provides single or multi-channel BER measurement capability with an unlimited number of channels.

Setup is so easy that you’ll be testing in seconds.

Compact architecture

The N4960A-CJ0/N4960A-CJ1 serial BERT controller (SSB16000/SSB16000J) is a platform that forms the basis of the stressed serial BERT. Based on our high performance N4972A-CJ0 (SCS16000) clock synthesizer, the N4960A-CJ0/N4960A-CJ1 serial BERT controller (SSB16000) adds the precision timing and control required for the remote pattern generator and error detector heads.

The concept of remote heads, first introduced in the N4965A-CTR (PCB12500) 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 at 17 Gb/s.

Affordability without compromise

The N4951A-P17 (PG17) pattern generator and N4952A-E17 (ED17) error detector remote heads operate from 4 to 17 Gb/s in a single band with no gaps or missing data rates. They generate and test full rate patterns directly without the need for external multiplexers and delay matching often used in other modular BERT systems.

Accurate, repeatable jitter tolerance

The N4960A-CJ0/N4960A-CJ1 serial BERT controller (SSB16000/SSB16000J) contains an accurately calibrated sinusoidal jitter source capable of high deviation at low frequencies, and lower deviation at frequencies up through 200 MHz.
