7 Recording Traffic

Once you have set up the mid-bus probe, please note that the Break Connection button in the
analyzer software does not function. This button is intended for use with the Teledyne LeCroy
interposers that have link disconnect functionality (Gen1 slot interposers).

For instructions on setting up and implementing a recording, please refer to the analyzer user manual.
