I'm so old I remember that you should always say hi in forums, do people still do that? I feel I should. My name is Gary, I'm fast approaching 60 and have bought a Rigol OScope which is a constant source of education. I live in Essex in the UK and have always liked basic electronics and mechanical fettling. I am owned by a wife, two kids and two cats, in that order.
A friend gave me a Hantek DSO5102P to look at with a dead channel. I put a sine wave on the input and used the Rigol to check the signal back through the circuit. It didn't get far as it didn't get past a four pin SMT Chip marked M 280 7336Q which seemed to be right behind the BNC socket, the first component. The other channel is fine and I used that to compare signals.
Q- I can't find any reference to this chip, any ideas? If you do know, how did you find out?
I have tried a blog search but can't find anything on this chip/package directly. Feel free to advise if I've done something silly, I'm on a journey and always try to take on advice. T.I.A.
Gary
