Creating and Downloading User-Data Files
Pattern RAM (PRAM) Data Downloads (E4438C and E8267D)
CAUTION Ensure that you do not use the :MEMory:DATA:PRAM:FILE:BLOCk command to download
an extracted file. If you use this command, the signal generator will treat the file as a
new PRAM file and translate the LSB of each byte into a 32-bit word, corrupting the file
data.
Command Syntax
This section lists the commands for extracting PRAM files and downloading extracted PRAM files. To
download an extracted file, you must use block data. For information on block data, see “SCPI
Command for a Block Data Download” on page 315. In addition, there are three ways to format the
file_name variable, which must also include the file path, as shown in the following tables.
There are two commands for file extraction:
• :MEM:DATA? <"file_name">
• :MMEM:DATA? <"filename">
The following table uses the first command to illustrate the command format, however the format is
the same if you use the second command.
