Waveform Storage and I/O
The AWG2021 has both internal memory and internal nonvolatile memory
(NVRAM) for waveform file storage. The AWG2021 generates waveforms from
files residing in internal memory. To save a file that is in internal memory, copy
it to nonvolatile memory or floppy disk. Only nonvolatile memory retains files at
power-off.
The AWG2021 also has a floppy-disk drive for loading files from floppy disk
into internal memory or internal nonvolatile memory, and for saving files from
either memory to floppy disk. The disk drive accepts 3.5-inch floppy disks in the
MS-DOS format.
Loading Files
The following steps explain how to load files from a floppy disk into internal
memory.
1. Push the LOAD/SAVE button in the MENU column.
2. Turn the disk so the side with the arrow is on top; insert the disk into the
AWG2021 floppy disk drive.
3. Push the Device button along the bottom menu to select Disk. The menu in
Figure 2–3 appears.
4. Select the Load All button along the side menu to load all files in the root
directory on the disk into the AWG2021 internal (volatile) memory. Or, turn
the general-purpose knob to highlight the file you want to load and select
Load. The display indicates which file it is loading. When loading is
complete, the clock disappears.
5. Push the floppy drive button and remove the disk from the floppy drive.
6. Push any button in the MENU column (other than LOAD/SAVE) to exit the
menu.
