Hi All,
I have used Tektronix DSO for signal measurement. While probing, instead of
ground reference, I have used 3.3V as a reference.
But I am not observe any difference between the signal probed with GND and
3.3V. My assumption was signal will be shifted with offset of 3.3V, but I am
surprised to see the signal without any changes as I measured with ground
reference.
Could someone explain about what is happing here? While connecting 3.3V to
ground DSO, what is happening?
Thanks & Regards,
Arun
