NRP18S-xx
Example:
You want to update your R&S NRP18S-10 with the
nrp18s_10_FW_15.02.12.01.rsu file. 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:
SYST:FWUP <block_data>
The <block_data> are definite length arbitrary block data as described in
FWUPdate
The size of the file is 10242884. This number has 8 digits. Thus, the <block_data>
consist of the following:
#
8
How many digits follow to specify the file size.
10242884
Number that specifies the file size.
<file_contents>
Contents of the *.rsu file, byte-by-byte
0x0a
Delimiter
In this example, you write exactly 10242905 bytes to the power sensor, for example by
using a 'viWrite()' function.
The 10242905 bytes result from the values of the list above:
9 + 1 + 1 + 1 + 8 + 10242884 + 1
In a (pseudo) string notation, the memory block looks as follows:
SYST:FWUP #810242884<file_contents>0x0a,
