gigaBERT - Bit Error Rate Tester
The GB1400 is a general-purpose 1400 Mb/s bit error rate tester (BERT) built to
meet the exacting standards of design engineers who need to verify and
characterize high-speed serial data transmission circuits, interfaces and systems.
While primarily a lab instrument, the GB1400’s compact design, full computer
programmability and relatively light weight also enable it to serve in
manufacturing ATE and field test applications.
The quality of a digital link depends on many factors, but everything comes down to the issue of whether the circuit exhibits a satisfactory BER (bit error rate) and has sufficient margin to function under stress conditions.
The GB1400 has all of the features you expect in a general-purpose BERT, and some you expect only in more expensive instruments, such as automated eyewidth measurements at a specified BER, and the ability to accept an external real-time data stream for bit error testing. Also, the GB1400 has options to add advanced features, such as Burst Mode (which also extends external clock range down to 150 kb/s), and a 1-Mbit programmable pattern memory option.
