The reason you are seeing the effects that have been observed is that the oscilloscope probe has an Input Resistance and Input Capacitance as shown in the manual for the MI007 oscilloscope probe.When connected to the top circuit across the capacitor, the output seems to be affected by the picoscope; the time constant is reduced to 0.1 seconds versus the expected 1.0 seconds and the amplitude is severely attenuated. When the picoscope is connected to the output of the op-amp, there is no noticeable effect on time constant or amplitude; the picoscope correctly graphs the output: time constant is 1.0 seconds, and the capacitor charges to 1.0 volts. The input signal period is 20 seconds, so the capacitor has plenty of time to charge and discharge. I watched multiple charging and discharging cycles.
