I have  been thinking of cascading two PTS synthesizers to add lots more

Has anyone tried it?
-------------------
Now there's a thought.
 
I don't suppose you could actually cascade two complete synthesizers,  I 
don't see any way for example that you could drive the second one with the  
output of the first, as the second would still need to start with a 10MHz  
reference and generate all the appropriate internal signals, including the high 
 frequency sections and the picket fence generator.
 
However, it would be very interesting to consider what might happen if  you 
were to add some extra DM modules.
I'm not sure whether or not it would be feasible but it would certainly be  
worth trying one extra module for starters, and if that works  then 
cascading the complete DM section of a second unit onto an existing  one.
 
I think though that I'd like to take a look at it on paper first  but I'm 
off to wild and windy Orkney for a few days to celebrate  Hogmenanny in good 
ole Scots Viking fashion so will take a look at it  when I return, assuming 
of course that I can still see anywhere near  straight:-)
