Eye Checker <EYE-1000C>
- Optical Sampling Oscilloscope -
|
The Eye-CheckerTM (EYE-1000C) optical sampling scope is a low-cost alternative to the conventional optical sampling oscilloscope, which requires an external electrical clock for synchronisation. The EYE-1000C employs an advance software algorithm, CODESYNCTM, to accomplish clock-recovery on any optical signal without the need for an external clock. The software also includes eye-diagram analysis, Q-factor and BER performance prediction, to data bit pattern unravelling, sequence recognition and visualisation.
The Eye-CheckerTM incorporates a proprietary carbon-nanotube-based pulsed
laser with an ultra-low jitter and a tunable repetition rate, enabling
a truly bit-rate independent measurement of any data format at bit-rates
up to 500Gb/s.
