They do have a USB 2.0 cable 4.5M (14.75ft) cable that you can use with the 4225 although it will lower the maxium sample rate.
The longest recommended length of a USB 3.0 cable is 9ft. Longer cables can be found from any electronics website but may affect performance or the scopes ability to power up. Don't buy a cheap cable.
Another alternitve would be an Active USB 3.x cable or extension which can go up to 50ft.
