When using matlab to read a Tektronix oscilloscope with GPIB and LAN ports, the data dimension taken back is always 1×2500 double. 

We use a DPO70000/B oscilloscope and use matlab to read oscilloscope data on a personal computer, but whether we use GPIB or LAN port, the returned data dimension is always fixed.

The data points are obviously too few, which does not support us in doing any big data experiments. So to consult with you if you know how to solve this problem, we need to read the entire oscilloscope screen, not part of it.
