DG2020A, P3410, & P3420 User Manual
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 DG2020A uses an instrument specific binary format
that is more compact than ASCII format.
Importing Large Data Files.
It is possible to create a CSV file that is larger than
the capacity of the 3.5 inch floppy disk which has a capacity of 1.2 Megabytes.
An extreme example is a 36 bit wide word pattern that has 65536 (64k) words. In
this example, the export file would be over 4 megabytes long. For the data to fit
onto a floppy, the pattern must be segmented into 16k blocks (16384 words) and
saved to individual floppies. To import the data do the following:
1. Insert the floppy with the first 16k into the drive.
2. Select File Import Data and select a file to be imported.
3. Press the OK button. The Import Configuration pop-up menu displays. 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.
5. Set the Dest Start point to 16536 for the second floppy.
6. Set the Dest Start point to 32768 for the third floppy.
7. Set the Dest Start point to 49152 for the fourth floppy.
