Firmware Update

R&S

NRPxxS(N)

61User Manual 1177.5079.02 ─ 10

Example:

You want to update your R&S NRP18SN with the nrp18sn_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 SYSTem:

FWUPdate on page 133.

The size of the file is 10242884. This number has 8 digits. Thus, the <block_data>

consist of the following:

●

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,
