10-2 2450-900-01 Rev. E / August 2019
How do I upgrade the firmware?
Do not turn off power or remove the USB flash drive until the upgrade process is complete.
The firmware file must be in the root subdirectory of the flash drive and must be the only firmware file
in that location. You can upgrade or downgrade the firmware from the front panel or from the virtual
front panel. Refer to “Using the 2450 virtual front panel” in the Model 2450 Reference Manual for
information.
From the front panel or virtual front panel:
1. Copy the firmware file (.upg file) to a USB flash drive.
2. Verify that the firmware file is in the root subdirectory of the flash drive and that it is the only
firmware file in that location.
3. Disconnect any input and output terminals that are attached to the instrument.
4. Turn the instrument power off. Wait a few seconds.
5. Turn the instrument power on.
6. Insert the flash drive into the USB port on the front panel of the instrument.
7. From the instrument front panel, press the MENU key.
8. Under System, select Info/Manage.
9. Choose an upgrade option:
To upgrade to a newer version of firmware, select Upgrade to New.
To return to a previous version of firmware, select Downgrade to Older.
10. If the instrument is controlled remotely, a message is displayed. Select Yes to continue.
11. When the upgrade is complete, reboot the instrument.
A message is displayed while the upgrade is in progress.
