Re: 2465B Screen artifacts


 

Hi, my name's Hachiroku.
1.36V and -1.25V Ref tested OK according to this post: /g/TekScopes/message/13732

Here are the voltage measurements (reference to ground) at the DAC pins.
DAC Pin 14=0.151V
DAC Pin 15 =0.147V
More voltages:
Voltage drop across R2013 (10K)= 8.82V
Voltage drop across R2016(10K)= 1.02V
Voltage drop across R2011 (4.75K)= 0.639V
Voltage drop across R2014 (221K)= 7.97V
Voltage drop across R2015 (82.5K)= 8.18V

It's a shame that I've decided to give it up as l observed different Serial Numbers on different parts of the scope. l assumed parts may have been replaced/repaired before by someone else.
Have a nice day Siggi and thanks for helping.
