Re. into 50 Ohm:
Be careful not to exceed the 'scope's maximum input on 50 Ohm.
It's not so much the rise time that your Rigol shows, it's the quality of the square wave that makes it useful, especially a flat top and no more than around 5% percent over- and undershoot, otherwise you could use a triggered Jim Williams pulser just as well.

Re. Unterminated:
The maximum safe input voltage of 'scopes is dependent on the input frequency. Check your 'scope's specs. Of course, if you use a 10x probe, it's not as risky.
