My google search showed the 561 mainframe is only good for 4 MHz, the
561A 10 MHz and the 561S for 30. The only way to get wider bandwidth is
with a sampling plug-in. 

561 plug ins tend to be 1, 2, and 3 number in the form 1A23... I've
still not gone back to the right vintage Tek catalogs, but I'm fairly
sure I have them.
