Thank you for your advice. I got everything working nicely, and just wanted to
confirm those values as working nicely.
I ended up using a simple resistive attenuator (made of discrete components) to
ensure the signal was within the limits set above, and so didn't have a didn't
have a chance to test the coaxial attenuators you recommended. Having said that,
I'm in the processes of buying some now.
Thank you for your help,
