The resulting plot in the Scope screen will look similar to one shown in
Figure 6-14. This plot shows the signal levels of the actual input signal (in volt s) .
As expected, the sine encoder signals are close to 1V peak-to-peak.

When exam ining the sine and cosine signals from a resolver, you need t o
multiply the signals by 0.0000939 (calculated from 1/32768 x 10/ 3.25).
The resulting plot in the Scope screen will look similar to one shown in
Figure 6-15. This plot shows the signal levels of the actual input signal (in volts).
