I am interested in measuring the noise in my set up. My Clampex software give about 40 pA (yes, I know it is huge) but nothing compared to the reading in my Techtronix digital oscilloscope (several volts!).
Who do I trust? I really doubt the osciloscope reading is right, but I don't know where the problem is. Of course it could be completely out of calibration, but it is almost brand new... Anyway, I plan to calibrate it tomorrow.
