10.Set the bandwidth and span according to Table 2-20.

11.Press 4MKR !5, MARKER ! HIGH , then record the MKR 1 TRK amplitude reading in the performance veri￿cation test record as indicated in Table 2-20.

The amplitude reading should be within the limits shown.

12.Repeat steps 10 through 11 for each of the remaining bandwidth and span settings listed in Table 2-20.
