Saving your waveform on the AFG 3000 isn’t in the Save/Recall menu. Instead, you need to go into the Edit menu, press “More” and select “Write To…”, and press the top bezel button to switch from internal memory to USB memory. You will now be able to save your waveform files with the extension TFW. You can now use the general purpose knob to select the file, and then press “Write” to save it into memory.You could also save to one of the four internal memories.  */
