Hi Hasham
Do you not understand anything???
My suggestion was that maybe the output of this LINAC device was outside the frequency range of the photo diode. That is the photo diode might not detect the LINAC output. I just don’t know and am not about to go searching to find out.
You have not even answered my earlier question about what the exact conditions were when the oscilloscope pics were produced.
This last post is only a repeat of what you have already produced and bears no resemblance to your last post.
I think you are determined to keep going in circles and are not interested in doing things in a logical order so I think I am out of here
Good luck.
Cheers Bob
I am also a bit concerned about repercussions on the medical side of things.
