I´m trying to rebuild a circuit whose schematic I have. I am using a different instrumentation amplifier but the same sensor. Using an oscilloscope at the output and putting the (vibration) sensor on a calibration exciter that produces a clean and constant vibration, the output for the first circuit is a clean sinusoidal signal, while on my new circuit it looks rather messy. As I do not have much experience with building electric circuits so far, my question is regarding the capacitors and the input resistors. I suppose that they are the reason for the different signals, as they are pretty much the only difference between the two circuits. Do I need more capacitance and also an RC-filter?
Below are three pictures: Old circuit, new circuit and both signals next to each other.
