Hello everyone!
I'm having a trouble with a Tektronix TDS 3045B oscilloscope.
Here is a screenshot of a signal where I connected the probe pin with its ground.
I can't understand where did that voltage come from. I need this measure to be very precise because I want to detect 4.88 mV signals
Should I use some filtering? If so, let me know some of your tips.
Thanks a lot
PS: The probe I'm using is a Tek P6139A
