LeCroy has again broken bandwidth barriers by utilizing widely adopted and proven SiGe processes, custom 2nd generation ASIC designs, and 6th generation Digital Bandwidth Interleave (DBI) technology to achieve unprecedented real-time oscilloscope performance.

The new line of LeCroy WaveMaster® 8Zi-A digital oscilloscopes, Serial Data Analyzers, and Disk Drive Analyzers—the 8 Zi-A Series—now provides up to 45 GHz of bandwidth and 120 GS/s of sample rate – the highest bandwidth and fastest sample rate real-time oscilloscope – combined with 768 Megapoints of analysis memory. Additionally, the introduction of a model with 20 GHz bandwidth on four channels provides the highest performance and signal fidelity available on four measurement channels. On all models, acquisition capability can be doubled with the use of the Zi-8CH-SYNCH Oscilloscope Synchronization Kit, with all acquired channels displayed on a single display grid.

The standard sample rate is 120 GS/s for 45 GHz bandwidth, 80 GS/s for 25 to 30 GHz bandwidths, and 40 GS/s on all 4 channels at 20 GHz bandwidth. For 4 to 20 GHz bandwidths, the standard sample rate is 40 GS/s on all four channels with an option to increase the sampling rate to 80 GS/s on two channels. All memory is available at full record lengths for analysis processing, 20 Mpts/ch is provided standard, with memory options up to 256 Mpts/ch available. In 120 and 80 GS/s mode, memory can be interleaved to 768 and 512 Mpts/ch.

LeCroy has designed the 8 Zi-A Series as a single hardware platform, supporting all nine models spanning from 4 to 45 GHz of bandwidth. All WaveMaster 8 Zi-A oscilloscopes are implemented with a single hardware platform. To extend bandwidth beyond 20 GHz, LeCroy has leveraged DBI technology to minimize initial costs—the module that doubles the bandwidth slides into a separate slot in the WaveMaster 8 Zi-A platform.
