Once the data words have been imported, parameters including clock rate, output
levels and inter-channel timing need to be set since the CSV format does not
transfer this information. After all operating parameters have been set, the entire
pattern can be stored on a floppy for non-volatile storage. The entire pattern will
fit on one floppy since the DG2030 uses an instrument specific binary format
that is more compact than ASCII format.
Importing Large Data Files. It may be possible to create a large CSV file.
Depending on what kind of operation is currently performed, the DG2030 may
not allocate the internal work space for creating CSV format data larger than
32768 words. An extreme example is a 8-bit wide word pattern that has 262144
(256 k) words. In this example, the export file would be over 4 megabytes long.
For the data to fit to work space and onto a floppy disk capacity, the pattern must
be segmented into 32 k (32768 words) blocks and saved to separate floppy disks.
To import the data do the following:
1. Insert the floppy with the first 32 k words into the drive.
2. Select File ! Import Data and select a file to be imported.
3. Press the OK button. The Import Configuration popup menu appears. This
menu allows you to configure how the data will be imported. In this
example, only the Dest Start point will be modified.
4. Set the Dest Start point to zero for the first floppy disk.
5. Set the Dest Start point to 32768 for the second floppy disk.
6. Set the Dest Start point to 65536 for the third floppy disk.
7. Repeat above step as incrementing the Dest Start point by 32768 until the
data from the last floppy disk is read.
Once the data words have been imported, parameters including clock rate, output
