6.1 Preparing the update
Firmware of R&S power sensors generally has an *.rsu extension, RSU meaning
Rohde & Schwarz update.
To download the update file
1. Download the most recent firmware version from the Rohde & Schwarz homepage
on the Internet, since the CD-ROM accompanying the power sensor contains the
firmware dating from the time of delivery. The latest firmware update files are avail-
able at:
www.rohde-schwarz.com/firmware/nrp-p
2. If the *.rsu file is packed in a *.zip archive, extract it.
3. Save the *.rsu file on the computer.
6.2 Updating the firmware
Do not interrupt the firmware update because an interruption can lead to missing or
faulty firmware. Take special care not to disconnect the power supply while the update
is in progress. Interrupting the power supply during the firmware update most likely
leads to an unusable power sensor that needs to be sent in for maintenance.
You can choose from several methods to update the firmware installed on the power
sensor.
6.2.1 Using the Firmware Update for NRP Family program
Firmware Update for NRP Family is part of the R&S NRP Toolkit. See also Chap-
ter 5.1, "R&S NRP Toolkit", on page 20.
You can perform a firmware update with Firmware Update for NRP Family only if the
power sensor is recognized as a VISA device.
To check the prerequisites
1. Ensure that a recent VISA software is installed on the computer.
