High-bandwidth oscilloscopes

10 November 2010 Test & Measurement

LeCroy’s line of WaveMaster 8Zi-A digital oscilloscopes now provides up to 45 GHz of bandwidth and 120 GSps sample rate – said to be the world’s 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 of true analog bandwidth on four channels provides high performance and signal fidelity on four measurement channels. On all models, acquisition capability can be doubled with the use of the Zi-8CH-SYNCH oscilloscope synchronisation kit, with all acquired channels displayed on a single display grid.

The standard sample rate is 120 GSps for 45 GHz bandwidth, 80 GSps for 25 to 30 GHz bandwidths, and 40 GSps on all 4 channels at 20 GHz bandwidth. For 4 to 20 GHz bandwidths, the standard sample rate is 40 GSps on all four channels with an option to increase the sampling rate to 80 GSps 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 GSps mode, memory can be interleaved to 768 and 512 Mpts/ch.
