Query
Description
Returns the trace pixel data (real pixel value x100)
for the selected trace in binary coded decimal
format, represented by 2 characters per pixel
(Highbyte_Lowbyte). Each trace has 601 pixels. In
total, the query will return 1203 characters (601x2 +
1 EOF character). If you wish to determine the real
value of a pixel simply divide the binary coded
decimal character by 100. A binary coded decimal
to ASCII lookup table is included in the Appendix
on page 227.
The pixel data that is returned is the y-axis pixel
data for each nth pixel. The pixel data is taken
from the display image data(450 x 600 pixels total).
Pixel value = 58 ~ 508
