2.15 MEMORY SCPI COMMANDS
The RFP system has a section of writeable flash memory that is reserved for
module specific data; this includes Model, Serial #, calibration, and hardware
initialization information. In some instances, depending on module type, LIST
sequences are also stored in this area. The
CRC:USRDAT? command
calculates and returns a CRC value for each file in the read / write file
system, it posts an error message if files have been added / removed or
changed without explicit command execution. If the supply is recalibrated
and the calibration is saved, this would not generate any errors as the file
update was explicitly requested.
The CLEar:USRDAT? command wipes the read / write file system of all files
and information that is not the minimum required for proper module operation,
it returns a CRC value for each of the required files, same as in the
CRC:USRDAT? Command.
If a hardware error occurs during the flash file system wipe process, an error
message will be posted.

2.15.2 MEMORY SCPI C OMMAND R EFERENCE
Command Description
MMEMory Memory subsystem.
: CLEar:USRDAT?
Wipes all data from the flash file system, and then restores the
required information. The response string format is the same as for
the CRC:USRDAT? command. If the read response times out, issue
a SYST:ERR? to read the hardware flash related error encountered.
This command typically takes 20 - 25 seconds to execute.
:CRC:USRDAT?
Returns a CRC value for each file in the file system. The format is
“#HXXXXXXXX,Filename;” for each file. The last file entry will not
have a “;” appended and will have the termination specified by
SYST:NET:TERM <+NRI> command.
