Why can’t I recall my arbitrary waveform file on the AFG3000 from my USB Stick?

Recalling your waveform on the AFG3000 isn’t in the Save/Recall menu. Instead, you need to go into the Edit menu, select “Read From…”, and press the top bezel button to switch from internal memory toUSB memory. You will now be able to see your waveform files with the extension TFW. Now use the general purpose knob to select the file, and then press “Read” to load it.You could also recall from one of the four internal memories.
