DRV8711: need help to plot winding current

Part Number:DRV8711

Hi ,

1) Where should I connect my Oscilloscope probe to get the wave foam for winding current ?

2) I am not getting a smooth and fine wave foam when connect to the sensing resistor pads , why?

3) Is the current probe is must for doing the motor tuning?

I am using the Oscilloscope -RIGOL 1052E  and the china stepper motor( I=1A ,R=6.6ohm, L=8.2mH) DPM57SH51-1A.

Please help.
