This softkey menu accesses the various parameters that govern the data received by the device under
test. The status area of the display shows the number of data lines used for both I and Q along with the
clock position relative to the data. When the port configuration is parallel or parallel interleaved, the
number of data lines indicated is equivalent to the word (sample) size. When the port configuration is
serial, the display will show that only one I and one Q data line is being used along with the frame
marker that delineates the beginning of a sample. Figure 7-12 shows the data setup menu structure.
