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. bye, Said In a message dated 10/31/2009 18:21:16 Pacific Daylight Time, [email protected] writes: Said, Thanks for the reply. This is certainly a starting point. A schematic would be wonderful. I have looked and have not found one yet. The units both provide about 4.5 VDC to the center pin when any port is connected to my Tbolt. However, the signal amplitude, as measured by TBoltMon, is essentially non existent on the 4 way splitter and divided by at least 2 on the 2 way splitter. Therefore, I suspect the amplifier is dead. Did not know about the voltage regulator. Will open one and get to work.
