Save the file to your computer and note the directory where the file is saved. A firmware update installed over the LAN, GPIB, or USB interface is a file with a .upd extension.
Unzip the file to access the .upd file. For updates using a front panel USB drive, the utility extracts the required files from the (unzipped) .upd file.
From the utility directory or Start menu, start the utility (FWUpdate.exe). The utility will prompt you for the location of the .upd file. Follow the additional prompts to complete the installation. The update may take several seconds to complete and will reboot the instrument. After the update is complete, exit the utility.
It is not necessary to re-calibrate the instrument following a firmware-update; however, the instrument may need to be re-secured if it was unsecured to perform the update.
