Usage
upgrade.unit()
Details
When upgrade.unit() is used, the firmware is only loaded if the version of the firmware is newer
than the existing version. If the version is older or at the same revision level, it is not upgraded.
When you send this function, the instrument searches the USB flash drive that is inserted in the
front-panel USB port for an upgrade file. If the file is found, the instrument verifies that the file is a
newer version. If the version is older or at the same revision level, it is not upgraded. If it is a newer
version, the instrument performs the upgrade. An error event message is returned if no upgrade file is
found.
