Purpose
This function performs a timed acquisition of voltage data from the analog channels specified in
the
channelString
. The acquisition does not start until the trigger conditions are satisfied.
If you have an E Series DAQ device, you can select Equivalent Time Sampling for the Trigger
Type to sample repetitive waveforms at up to 20 MHz. See the help for the Trigger Type
parameter for details.
