The Y index (for QMatrix method) associated with this count value.
The sensor pair index (for QTouch method) or X index (for QMatrix method) associated with this count value.
The signal (number of counts) acquired on the channel specified in the SPORX and Y fields.
When multiple acquired count values are read from a QTouch acquisition, the Y field will always be 0 and the SPORX value will
increase monotonically. For example, suppose a QTouch acquisition is performed using sensor pairs SP1, SP4, and SP9. The
first count read will have SPORX=1, the second read will have SPORX=4, and the third read will have SPORX=9.
When multiple acquired count values are read from a QMatrix acquisition, the SPORX value will stay the same while Y
increases monotonically through all Y values in the group. Then SPORX will increase to the next X value in the group. For
example, a QMatrix acquisition with X=2,3 and Y=4,7 would provide count values in the following order: X=2 and Y=4, then X=2
and Y=7, then X=3 and Y=4, and finally X=3 and Y=7.
