Creating and Downloading User-Data Files
User File Data (Bit/Binary) Downloads (E4438C and E8267D)
Bit and binary files increase in size when the signal generator loads the data from non- volatile to
volatile memory. For more information, see
“User File Size” on page 292 .
Use the following SCPI commands to determine the amount of remaining memory:
Volatile Memory :MMEM:CAT? “WFM1”
The query returns the following information:
,,<“file_names”>
Non- Volatile Memory :MEM:CAT:ALL?
The query returns the following information:
,,<“file_names”>
NOTE The signal generator calculates the memory values based on the number of bytes used by the
files residing in volatile or non- volatile memory, and not on the memory block allocation. To
accurately determine the available memory, you must calculate the number of blocks of
memory used by the files. For more information on memory block allocation, see
“Memory
Allocation” on page 283 .
User File Data (Bit/Binary) Downloads (E4438C and E8267D)
NOTE This section applies only to the E4438C with Option 001, 002, 601, or 602, and the E8267D
with Option 601 or 602.
If you encounter problems with this section, refer to “Data Transfer Troubleshooting
(N5182A, E4438C and E8267D Only)” on page 340 .
To verify the SCPI parser’s responsiveness when remotely using the :MEM:DATA SCPI
command to upload files, the file’s upload should be verified using the *STB? command.
Refer to the SCPI Command Reference.
