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 */
/* Reading Byte and Word format Example. This program demonstrates the order of
commands suggested for operation of the Infiniium oscilloscope by LAN or GPIB.
This program initializes the scope, acquires data, transfers data in both the
BYTE and WORD formats, converts the data into hex, octal, binary and time values,
and stores the data in a file as comma-separated values. This format is useful
for spreadsheet applications.
