LeCroy has developed a kit to couple two four channel 30GHz scopes, allowing analysis 56Gbit/s IQ modulated QPSK.
Aimed at the WaveMaster 830 Zi 30, the Zi-8CH-Synch also allows eight channel 16GHz operation.
"The oscilloscope synchronisation kit is comprised of a small hardware module that plugs into one of the two oscilloscopes," said LeCroy. "Once attached, it identifies that oscilloscope as the master for display and control purposes. A variety of other cables for trigger synchronization, clock sharing, and data transfer are connected between the master and a slave oscilloscope."
Triggering of both scopes may be performed in a pseudo-auto trigger mode, or by customer trigger signal.
"Upon successful trigger, all waveforms from both the master and the slave are displayed on the master's grid for viewing, debug and analysis. The complete setup time is no less than five minutes prior to de-skewing channels," said the firm.
The kit is compatible with all 8 Zi models, so it may be used to create four channel data captures from 20 to 30GHz or eight channel data captures from 4 to 16GHz. It requires software version 6.0.1.x or later.
At the European Conference and Exhibition on Optical Communication (ECOC) held in September 2009, according to LeCroy, a research team led by Dr Peter Winzer of Alcatel-Lucent presented a paper on the first 56Gbaud coherent detection with full digital impairment compensation to be transmitted over a single-channel - twice the rate of the previous record.
