SYSTem:FWUPdate
<fwudata>
Loads new operating firmware into the device. Rohde
&
Schwarz provides new
firmware in files with the extension
*.rsu
.
Usually, you find the
*.rsu
file at the Rohde
&
Schwarz web site. Otherwise,
consult the customer support or the product marketing.
In addition, Rohde
&
Schwarz provides dedicated programs for loading new firm-
ware into a R&S
NRPM sensor module (e.g. PureFW).
If you want to integrate a firmware update function in your 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 pre-defined format.It consist 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:
If you want to update the firmware of the R&S
NRPM, you first need an update
file, e.g.
nrpm3_FW_15.02.12.01.rsu
.
