Hey Guys,
I have lots of experience working on these scope. If you need help and/or advice ask here and we will try to help.
Hi
Can somebody confirm whether in DPO4034B the +1.5V rail (in the row of power supply test points) is up and running after turning on the scope?
I have a DPO4034B stuck at splash screen and the remedies mentioned in this thread didnt help. However, I noticed that all power supplies
are ok except that +1.5V which reads ZERO
I have spent a couple of hours trying to trace that rail to where it is generated and/or where it is used with no luck
I am beginning to think that maybe it just does not exist on 4034B and only exists on MSO or 4104B or on MDOs?
I do not see it being used anywhere on the board except by an uninstalled chip.
Still I could be totally wrong and have not seen its origin.
