upgrade.unit()

This function upgrades the Model 2450 firmware.
Type TSP-Link accessible
Function No
Usage
upgrade.unit()
Details
When upgrade.unit() is used, the firmware is only loaded if the version of the firmware component 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 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 is returned if no upgrade file is found.
