I am having trouble finding info on how to transfer data that I saved in the OSA to my controller PC through an NI GP-IB USB HS+ cord. I am doing this via pyvisa. I just want to save data on my OSA then retrieve it with a python script through the GP-IB (mostly csv files), without the need of the external thumb drive. I've been doing a lot of work arounds (i.e. saving data from the OSA to variables in my python script then saving those to a .csv file), but this eliminates a lot of pertinent information that normally is included on the saved files you grab with a usb thumb drive. Any help would be appreciated!
