BMP is an uncompressed format and uses a lot of space, but
maintains sharp images. JPEG is a compressed format and uses far
less space than BMP, but can blur lines and text. PNG is a com-
pressed format and maintains sharp lines and text. Table 3--28
compares the relative features of each of the export file formats.

An exported trace file contains information about the YBT250
settings and data that represents the trace. Figure 3--74 shows an
example of an exported trace saved as a tab-separated text file. The
numbers at the end (following “Trace 1 data”) represent the data
points of the trace on the display. To save space, only a few numbers
are shown in Figure 3--74.
