Eye
CheckerTM <EYE-2000C>
- Picosecond Optical Sampling Oscilloscope
-
|
The Eye-CheckerTM (EYE-2000C) optical sampling oscilloscope is a low-cost alternative to
the conventional optical sampling scope, which requires an external electrical
clock for synchronisation.
The EYE-2000C employs an advance software algorithm,
CodeSyncTM, to accomplish clock-recovery on any optical signal without
the need for an external clock. The latest software included with the
scope is fully native C compiled utilising OpenGL ultra-fast graphical
library for real-time operation with functionalities such as
eye-diagram
analysis, Q-factor and BER performance prediction, to data bit pattern
unravelling, sequence recognition and visualisation. Options for a
second optical channel for applications requiring two synchronised
optical signals, DPSK signals, optical or electrical clocking and
triggering for packet, or burst signals are also available.
The Eye-CheckerTM incorporates proprietary carbon nanotube based fundamentally mode-locked
laser with ultra-low jitter, enabling bit-rate independent measurement
of any data format at bit-rates up to and beyond 640Gb/s.
