Configuring Channels for Different Acquisition Modes in LabVIEW
To enable multiple mode scanning in using NI-DAQ functions, call the
AI_Configure
function for each channel.
How can I use the STARTSCAN and CONVERT* signals on the
NI 6052E device to sample the AI channel(s)?
NI E Series devices use the STARTSCAN and CONVERT* signals to
perform interval sampling. As Figure C-2 shows, STARTSCAN controls
the scan interval, which is determined by the following equality:
