Figure 5.8: Recording Mode Options
5.11.1 Bit Tracer Recording

This option does not have Simple Mode and Advanced Mode. Therefore, Upload Size,

The PETracer application forces this option when the user selects a large buffer size for
recording. This is done to limit the size of individual trace files to a level that the PETracer
