This function allows you to make a deferred data-collection request, which will later be
executed, and the arguments validated, when you call
mode. The advantage of this method is that the driver makes contact with the scope
only once, when you call
, compared with the two contacts that
occur when you use the conventional
sequence. This slightly reduces the dead time between successive captures in rapid
block mode.
After calling
, you can optionally use
further copies of the data. This might be required if you wish to display the data with
different data reduction settings.
