Visually verify that the Activity Indicator dialog box shows activity on all
probe channels that are connected to the test fixture (see Figure 34).
Note the signal activity for the clock, qualifier and data channels for the C3,
C2, C1, and C0 probe sections. Also note that there is no activity on other
probe sections because the probes are not connected to a signal source. (The
channels are all high.)
