Compare Recall and Pair 1 Test
The Compare Recall and Pair 1 test is used to compare a previously stored
trace with a "live" trace on Pair 1. The format of the results is like those shown
in Figure 6-3, in which two "live" signals are displayed for comparison. In this

Pair 1 test result screen (see "Pair 1" and Table 6-3 for descriptions).
