BertScope boosts speed, decomposes jitter
-- Test & Measurement World, 2/11/2009 2:23:00 PM
Synthesys Research has boosted the speed of its flagship BertScope BER tester from 125 Gbps to 17.5 Gbps. The higher speed lets the instrument perform BER tests and display eye diagrams on 14-Gbps Fibre Channel devices and systems. The model 17500A can analyze serial data streams from 500 Mbps to 17.5 Gbps.
The company has also added a software option called Jitter Map to the BertScope line. Jitter map uses the BertScope’s BER tester to decompose jitter into random and deterministic jitter, then further decomposes deterministic jitter into data-dependent jitter, bounded uncorrolated jitter (such as sinusoidal), intersymbol interference, and other components, displaying them as a map of total jitter.
Jitter Map analyzes signals for bounded uncorrolated jitter by looking at the same bit in a PRBS pattern. Such analysis lets you find which bits contribute to bit errors. It also contains a divider that lets you look at a clock rate divided by two, four, five, etc. and display an eye diagram for each one. This lets you find which clock signals in a circuit contribute to periodic jitter.
Making jitter and BER measurements on long bit patterns such as PRBS31 can take quite a bit of time. To reduce that time, Jitter Map uses data obtained from short patterns such as PRBS7. It then measures total jitter on the longer pattern and calculates the jitter components based on the shorter patterns.
