Hi Didier,
looking at the 10MHz input schematics, there is probably an opportunity to  
make these 5370B units a lot better. Even the 50MHz and 200MHz multiplier 
boards  could be done a lot better nowadays, say with Crystal based VCXO's.
I always like opportunities like this that give better performance in an  
evening or two worth of experimenting.
