LeCroy releases 100 GHz real-time oscilloscope for R&D

November 03, 2014 // By Graham Prophet
Previewed in a number of demonstrations since July 2013, LeCroy has now formally released its 100 GHz, 240 Gsample/sec LabMaster 10-100Zi oscilloscope, aiming it a engineers working on next-generation communication systems.

This introduction, says Teledyne LeCroy, “continues to demonstrate a long running commitment to leadership in the high end oscilloscope market by aggressively pushing real-time bandwidth and sample rate boundaries”.

The LabMaster 10-100Zi is the newest acquisition module in the LabMaster 10 Zi Series of high-performance modular oscilloscopes. LabMaster 10 Zi is a modular and flexible platform that allows users to build oscilloscopes with high channel counts, even when only one or two channels are in the base model. LabMaster 10 Zi oscilloscopes are built from a single LabMaster Master Control Module (MCM-Zi) that contains the display, control, and ChannelSync clock distribution architecture; all managed by a server-class CPU. Users connect up to 20 acquisition modules, including the LabMaster 10-100Zi, in order to build oscilloscopes with up to eighty channels at 36 GHz, twenty channels at 100 GHz, or anything in between.

The LabMaster 10-100Zi was, the company says, recently used by Alcatel-Lucent to demonstrate the highest-bandwidth coherent optical receiver capable of detecting a 160 GBaud QPSK signal. “As we research new ways to expand the amount of data that future optical communications networks will be expected to carry, we demonstrated a record 160-GBaud QPSK system prototype. The 100-GHz bandwidth and 240-Gsample/sec sampling rate were key in building this system", says Dr. Peter Winzer of Bell Labs, the industrial research arm of Alcatel-Lucent. "....the oscilloscope's bandwidth is no longer the limiting factor in our research; it currently exceeds the bandwidth of the transmitter and optical-to-electrical converter in the receiver."
