My TEKTRONIX TDS 2014 is broken and cannot measure anymore. TEKTRONIX service man wasn't helpfull with me and just wanted to sell me a new model.
So I decided to open the enclosure myself in order to search for the problem.
There is an ic on the measurement pcb board with the label : EE56ES 9857-00 that is very hot and I think that there is the malfunction.
My problem is that I cannot find anything about this ic.
Would you able to help me ?
Thanks in advance.
