RoeTest Kyle Werner, USA 20.10.2020  His Message: Hello
Helmut,
I
have finished the project today and everything is working great. Thank you for providing detailed documentation and helpful tips.
I ran into trouble calibrating the G1. I could not get it past -40 volts and saw
where you warned that having too much offset means the op amp could be faulty. I
reflowed the LTC6090 and it was able calibrate with little offset after that. I
think the pad on the bottom failed to connect.
My
design was inspired from a recycled case I used from an old 70's oscilloscope. I
mounted the board to the sides so I could remove both the top and bottom panels
and access everything if I ran into trouble. I am concerned with oscillations
because I have the socket wires very long. What will it look like when there is
an oscillation problem?
Attached
are some pictures of the final build.
Thanks
again!
Kyle
Werner
