// Actual hardware value at
123,99,123,99
// Setting trigger source will not affects
the output value. Thus, output values
remained
// Configure output value only. The
actual hardware output did not change
yet, still remain at 123,99,123,99
// Actual hardware value is
123,99,123,99 but SCPI show
44,44,222,222. The SCPI value will be
source out, if the DAQ receives the
trigger signal
// User decides not to use trigger
function anymore. Trigger does not
happen
// Since trigger did not happen, the
output value did not change. Thus
SCPI return 123,99,123,99 to show the
actual hardware status
