Defpom ,
Was Right ! it is from an Agilent E3646A and even better I found the problem with it.
It was not working and the voltages were all over the place when I installed it in an E3646A. If you look around the net you will see a totally different PCB used in the E3646A , this is why i suspected it was the wrong PCB.
Well anyhow, there is two electrolytic's on the PCB , both read good in value but one was leaking really bad. I replaced it and all booted up fine. Note: The revision A , digital PCB is not what you see in the manuals and not what you will see on the net.
Now to finish the repair. Channel one is perfect and channel 2 is dead. Should be easy enough now.
Thanks all,
