SYSTem:FWUPdate
<fwudata>
This command is used to load new operating firmware into the device.
Rohde
&
Schwarz provides new firmware in form of
*.rsu
files. An
*.rsu
file often
can be downloaded from the Rohde
&
Schwarz web sites or can be supplied by the
customer support or the product marketing. The
*.rsu
file is usually packed in a
*zip
archive that must be extracted before.
If you want to integrate a firmware update function in their own application, use the
SYSTem:FWUPdate
command. The parameter of this command is a "Definite Length
Arbitrary Block Data" containing the direct copy of the binary
*.rsu
file.
A "Definite Length Datablock" has a well-defined format. It consists of:
●
A '#' sign.
●
A single digit indicating the length of the number which represents the size of the
binary file.
●
The binary data.
●
An appended delimiter (LF, 0x0a).
Example:
Lets assume that this file has a size of 10242884 bytes.
To send the file to the sensor for updating the firmware, your application has to assem-
ble a memory block containing:
●
The command.
●
The "Definite Length Block" header.
●
The contents of the
*.rsu
file.
●
A trailing delimiter (0x0a = Linefeed.
