24. Frequency Response, Agilent E4404B, E4405B, E4407B, and E4408B
14.Note the most negative number from the Flatness Relative to 
50 MHz (ac) column of Table 2-52 for frequencies between 6.7 GHz 
and 13.2 GHz. Record this number in Table 2-56 as the Minimum 
Response for Band 2.
15.For Band 2 in Table 2-56, subtract the Minimum Response value 
from the Maximum Response value and record the result in the 
Peak-to-Peak Response column.
16.Note the most positive number from the Flatness Relative to 50 MHz 
(ac) column of Table 2-52 for frequencies between 13.2 GHz and 
26.5 GHz. Record this number in Table 2-56 as the Maximum 
Response for Band 3.
17.Note the most negative number from the Flatness Relative to 
50 MHz (ac) column of Table 2-52 for frequencies between 13.2 GHz 
and 26.5 GHz. Record this number in Table 2-56 as the Minimum 
Response for Band 3.
18.For Band 3 in Table 2-56, subtract the Minimum Response value 
from the Maximum Response value and record the result in the 
Peak-to-Peak Response column.
19.Transfer the values entered in Table 2-56 to the test record in this 
guide.
20.The frequency response test for Agilent E4407B analyzers with 
Option UKB is now complete.
