AN957: TouchXpress™ Configuration and Profiling Guide
Simplicity Studio Tools
In order to more closely examine sensor performance, set the tool to display only one sensor by checking only one box in the [Selected
Channels] window. Alternatively, just type the channel number into the text box.
Ensure that data fills the entire viewing space by enabling the y-axis adjustment feature button along the top of the graphical view.

Finally, add or remove data types from the graphical display using the [Selected Data Types:] list. In this case, Thresholds, Raw data,
Baseline, and Expected Range are displayed. Note that the expected range is over twice the delta of what is reached by touching a
sensor. This is due to the fact that the board under test is using a 1/8th inch overlay, and the default touch deltas are configured to
expect a 1/16th inch overlay. Upon examination, it looks as though the touch deltas seen during a touch are closer to 300 codes.
