Keysight 81150A - Software Update

Appendix
286
3.17 Software Update
Introduction
The Software Update screen gives you prompt information about the 81150A
/ 81160A.
The software update package contains two firmware images. Both will be
extracted to the USB memory device during the update process. In case of a
power-loss during the update, the instrument will load the recovery image
from the USB memory device if the regular firmware image is corrupt.
This recovery image will continue the update process in case of a
completely or partially erased or incomplete (not yet updated completely)
firmware image.
To ensure that this recovery mechanism is working, the USB memory device
may not be unplugged until the instrument has booted into the upgraded
firmware.
Requirements
 USB Memory device with at least 100 MB of free space.
 The USB memory device must be formatted as a hard-drive with a
primary partition. The partition has to be formatted using the FAT or
FAT32 file system.

 Do not use USB memory devices that contain extended partition. The
instrument will not be able to recover from a failed update from such
memory devices.
 USB memory devices that are formatted as a super floppy are not
supported and hence will not be recognized by the instrument.
