AFE4300EVM-PDK: Current source signal problem

Part Number: AFE4300EVM-PDK
Hello,
    I use AFE4300EVM-PDK to measure some resistance. For example, IOUT0 and IOUT1 are used as the current source, VESNS0 and VSENS1 are used as voltage measurement points.
    Then I used an oscilloscope to detect the signal waveform at both ends of the resistor and got the result that there is a signal at one end of the current output and almost nothing at the other end.
    But in the users manual and the GUI interface, FB0 and FB1 are the output and input of the amplifier. Does this contradict the results above? Is there something wrong?
Regards,
Haoger
