Scope decodes CAN bus symbols

Staff -- Test & Measurement World, 11/1/2005

LeCroy's Vehicle Bus Analyzer (VBA) is an oscilloscope and protocol decoder for the CAN bus. The VBA is based on the Waverunner scope platform. It lets you see electrical signals on the CAN bus, and it decodes the signals into bus symbols, eliminating the need for a protocol analyzer. Because the VBA has four scope channels, you can view and decode the bus while looking at other signals such as those from sensors or engine control units. Or, you can view and decode up to four CAN buses at once. You can set up triggers based on CAN bus symbols to isolate events.

LeCroy offers two VBA models: the VBA 6050 ($18,900) is a 500-MHz scope with 2 Msamples of waveform memory on four channels or 4 Msamples on two channels. The VBA 6100 ($23,990) has 1 GHz bandwidth. It can interleave both sampling rate and bandwidth to achieve 10 Gsamples/s and 4 Msamples/channel on two channels. LeCroy, www.lecroy.com.
