Only a waveform with up to 131,072 points can be transferred to the AFG31022 via ArbExpress or any other external means due to the limit of the AFG's edit memory being 131,072 points. To transfer the waveform file with more points to the AFG you must save the waveform as a .tfwx file in ArbExpress, and put the waveform file on a USB drive. After, you must plug in the USB drive into the AFG31022 and transfer the file with 13M points to the AFG31022. You will then be able to use the waveform file in advanced mode. Note that in Basic mode you will not be able to use the file as Basic mode only supports up to 131,072 points.
