DATA? Example
for Digital
Channels
The following C example shows how to transfer both BYTE and WORD
formatted waveform data for digital channels to a computer. There is a file
on the Infiniium Oscilloscope Example Programs disk called readdig.c in
the c directory that contains this program.
/* readdig. c */
