I want to use Matlab (installed on PC ) to control GPIB to load an ARB waveform with about 48000 points into 33250. I already checked the memory size of 33250 can support over 64000 points. I was able to download a data with 24 points to the signal gen. It works. But over 24 points, like 48 points, there would be an error. And the output of 33250 will be changed to EXP_RISE signal. Then I tried to send the command 'APPLY:USER VOLATILE'. It did not work. Does anybody know how to load a data to 33250? Thanks a lot.
