Data Buffer Memory
The E4980A/AL has a data buffer memory function. The data buffer memory
can hold up to 201 sets of measurement results, and all buffered measurement
results are transferred at once to the controller by using the :MEM:READ?
DBUF command. This function makes it possible to greatly reduce the overall
time for data transfer.
Refer to the following figure. Line numbers in the figure correspond to those of
the reference codes below the figure.
