Data flow (remote operation)

Remote operation can be used with triggering configured to perform a specified number of
measurements and then stop. The various read commands (SENS:DATA?, FETCh?,
READ?, MEAS?, CALC2:DATA?, TRACe:DATA?, and CALC1:DATA?) return the data
array(s) acquired during the measurement cycle. Data flow for this triggering configura-
tion is summarized by the block diagram shown in
for the following discussion.
