Firmware
The Firmware tab is available over USB. All three update sections use the mainboard's USB connection; firmware updates are not available through the WLAN WebUI.
Keep the instrument powered and the USB connection in place until the update has finished. Use the firmware file intended for the component you are updating.

| Flash mainboard | Writes the selected firmware and verifies it. Follow the progress and result shown below the controls. |
