Figure 6.43: Second step of the Measurement Setup Wizard
After clicking on the Next button, we will get to the Signal Preprocessing dialog
where the Automatic Delay Compensation function, the Static Gain
Compensation function and the Remove DC from Signals option (see Figure
6.44) are selected. Finally click the Finish button to start the actual analysis.
After the computation of the delay has been finished, select the diagram types
for display, for example Final Results for the upper diagram and MOS vs. Time
for the lower diagram panel. Depending on the reference signal and the
resulting test signal being used, the view on the measurement will look similar
to the view depicted in Figure 6.45.
