How do I update the firmware on my AFG3000?

Go to www.tektronix.com and search for your model AFG and select by software. You will want to find the latest firmware file and download it to a USB flash drive. Then insert into the front of the AFG and start by selecting the  'Utility' menu button, select 'more' twice, you should see 'Firmware Update'. From here select the file and click 'Execute'. This will update the firmware on your AFG. Make sure you don't remove the USB flash drive too early as this could corrupt your update.
