LeCroy Introduces 30 GHz/Four-channel Real-time Oscilloscope Solution

March 3, 2010

LeCroy Corp. has extended the power of its WaveMaster® 830Zi 30 GHz real-time oscilloscope by providing a simple and fast method to combine two oscilloscopes and provide four channels at 30 GHz. This solution is ideal for measurement and analysis of 28 to 56 Gb/s IQ modulated signals where ultra-high real-time bandwidth and four channels is required, or for capture and detailed analysis of other leading-edge technologies. The solution is enabled with the Zi-8CH-SYNCH Oscilloscope Synchronization Kit, which is compatible with all WaveMaster 8 Zi models, so it may be used to create four channel data captures from 20 to 30 GHz or eight channel data captures from 4 to 16 GHz.

The oscilloscope synchronization kit is comprised of a small hardware module that plugs into one of the two oscilloscopes. 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 oscilloscopes may be performed in a pseudo-auto trigger mode, or by application of a customer trigger signal. Upon successful trigger, all waveforms from both the “Master” and the “Slave” oscilloscope are displayed on the “Master” oscilloscope grid for easy viewing, debug and analysis. The complete setup time is no less than five minutes prior to deskewing channels.
