Storing a PRAM File to Non–Volatile Memory and Restoring to
Volatile Memory
After you download the file to volatile memory (waveform memory), you can
then save it to non–volatile memory. Remember that a PRAM file downloads to
waveform memory. Conversely, when you store a PRAM file to non–volatile
memory, it uses the same directory as waveform files. When storing or
restoring a file, you must include the file path as part of the file_name variable.
Command Syntax
The first file_name variable is the current location of the file and its name; the
second file_name variable is the destination to store the file and its name.
There are three ways to format the file_name variable to include the file path:
Extracting a PRAM File
When you extract a PRAM file, you are extracting the translated 32–bit word–
per–byte file. You cannot extract just the downloaded data. Extracting a PRAM
file is similar to extracting a waveform file in that you use the same commands,
and the PRAM file resides in either volatile memory (waveform memory) or the
waveform directory for non–volatile memory. After extraction, you can
