Noises when measure capacitance using FDC1004EVM

Other Parts Discussed in Thread: FDC1004EVM

Hello,

I got lots of noise while streaming data using the FDC1004EVM. Is it because I don't use coax cables and nor solder the connectors onto the board? Will all the noise go away when I do that? Is there any way to completely get rid of the noise?

When I took of the test sensor and connect the circuit to my laptop and run data streaming, this is what I have,

Is it normal to have signals like that? Will I get just straight lines if I connect a capacitive sensor with all the shieldings to the circuit?

Thank you,

Huy
