Hi Joe,
I have the same problem with my Thunderbolt even though my splitter works
well. Not sure why. This is especially so if I cascade the Agilent unit
with a passive splitter, I can never get the Thunderbolt to lock up.
I think the added noise of the Amp may play funny with the Thunderbolt's
receiver, and there may not be anything wrong with your splitter.
M12M's and uBlox receiver's don't have a problem at all, even if two units
are cascaded. They do start to have issues with three splitters in series.
Do you have another receiver you can try?
In terms of schematics, it's really straight forward, see the Mini-circuits
website for sample schematics for the ERA part, the agilent unit has
pretty much the same setup.
The amp is followed by a resistive splitter, and possibly a resistive
attenuator (on the 2-port version). Then a cavity filter, then the N-Connector,
very simple, not much that can go wrong.
They do have DC load on the non-DC-thru ports.
Check the open/short status on the thunderbolt. It's very easy to see
with the Thunderbolt monitor program.
Cheers,
Magnus
