Well, I failed to find a Thanksgiving bargain on a Rigol DSA815-TG, so I just ordered one from Emona. That's OK. John's a cool guy to deal with.
As I mentioned in another thread recently, I have never used one before and this is pretty much a Xmas toy: I have no idea what accessories I'll require.
If anyone has suggestions, especially with links, for adapters, leads and so on, I'd be very grateful.
