7.Press 4MKR !5, MARKER ! HIGH , then record the MKR 1 TRK amplitude reading in the performance veri￿cation test record as indicated in Table 2-19.

The amplitude reading should be within the limits shown.

8.Repeat steps 6 through 7 for each of the remaining bandwidth and span settings listed in Table 2-19.
