Newport ESP300 Series - DD Get Data Acquisition Done Status

PARAMETER nn5: The rate at which data is to be acquired is specified through this
parameter. The rate specified is in multiples of the servo cycle rate. For example, a value
of 0 implies data acquisition every servo cycle, a value of 1 implies every other servo
cycle, and so on.
PARAMETER nn6: The number of samples of data to be acquired is specified through
this parameter. Data acquisition process is considered to be "done" only after the number
of samples specified by this parameter are acquired by the controller. The status of data
acquisition process may be found by issuing ASCII command, DD. Once the data
acquisition is done, ASCII command, DG may be used to collect the data from the
controller.
Note:
The controller responds with a servo cycle tick count along with every data sample
collected.
RETURNS None.
REL. COMMANDS DD - get data-acquisition done status
DF - get data-acquisition status – number of samples collected
DG - get data-acquisition data
nn1=1 : Start data acquisition when trigger axis start motion
nn2=1 : Trigger axis is 1
nn3=0
