Rigol DSA815-TG Block Diagram anyone?
« on: August 27, 2014, 12:05:08 pm »
Hi,

I am in the long process of making an external 3GHz extension for a Rigol DSA815TG. Now asking for a service manual would be too much I know but has anyone seen, and can share, a block diagram. Dave's tear-down goes so far but not quite enough.

I want to avoid spurs if possible; hence I'd like to know the mixing process.


Cheers - Joe

Maybe you could use an expander like this one ?

Hi,

You are right, I could use a device such as you mention but the price puts it out of my league.


Thanks - Joe
