96 Suzuki X-90: Testing the CMP and CKP with an Oscilloscope

This X-90 is throwing a code P0335: Crank Angle Circuit. The best way to see how the crank angle sensor and cam angle sensor are working is with an oscilloscope. The first signal is directly at the CKP sensor. The second signal is CKP signal at the computer and the third signal is the CMP signal at the computer. I see a pulsation in the CKP signal at the computer and im not sure what this is.
