WaveMaster 830 Zi oscilloscope

LeCroy rolls out a solution that lets it extends the WaveMaster 830 Zi 30GHz real-time oscilloscope, by combining two oscilloscopes and provide four channels at 30GHz.

This solution is suitable for measurement and analysis of 28- to 56Gbps 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 synchronisation kit, which is compatible with all WaveMaster 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.

The oscilloscope synchronisation 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 synchronisation, 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.

Complete setup takes less than five minutes prior to de-skewing the channels.
