App Note: Protocol Analyzer Firmware and Bus Engine

Each LeCroy Protocol analyser uses two
special pieces of code in addition to the user
application. These are called the “BusEngine”
and “Firmware” and are essential to the
operation of the analyser in combination with
a particular application revision. This
application note looks at why they are needed
and how to update or change them if required.
