As described in Chapter 4, the delay between the reference and the test signal is
checked permanently in Normal Mode. In some measurement cases notice that
the displayed value for the detected delay in the field to the right of the diagram
panes changes. When stopping the permanent delay detection while keeping a
certain delay value, choose the Freeze Delay option by pressing the toolbar
button shown in Figure 5.37 or the corresponding menu option from the
menu topic Measurement. After doing so, the status display to the right of the
diagrams will indicate this mode by displaying "Frozen".
