Original packaging Containers and materials identical to those used in factory packaging are available through Keysight offices. If the instrument is being returned to Keysight for servicing, attach a tag indicating the type of service required, return address, model number, and serial number. Also, mark the container FRAGILE to assure careful handling. -
