Performance Verification Tests
24. Frequency Response, Agilent E4404B, E4405B, E4407B, and E4408B
26.Repeat step 10 through step 14 for frequencies up through
13.199 GHz making entries in the ac Coupled column of Table 2-52.
27.Continue with “Agilent E4404B/E4405B Test Results” (for an
Agilent E4405B only). The following steps apply to the Agilent
E4407B and E4408B only.
28.Set the synthesized sweeper FREQ STEP to 500 MHz.
Set the analyzer center frequency step size to 500 MHz by pressing
FREQUENCY, CF Step, 500 MHz.
29.Repeat step 10 through step 14 for the remaining frequencies in
Table 2-52. If the analyzer under test is an Agilent E4407B with
Option UKB then continue with the next step. Otherwise, continue
with “Agilent E4407B/E4408B Test Results” (for an Agilent E4407B
or E4408B only).
30. On the analyzer, press Input/Output (or Input), Coupling (AC). This
sets the analyzer to ac coupled mode.
31.Repeat step 4 through step 15, making entries in the ac Coupled
column of Table 2-52.
32.Set the synthesized sweeper FREQ STEP to 400 MHz.
Set the analyzer center frequency step size by pressing FREQUENCY,
CF Step, 400 MHz.
33.Repeat step 10 through step 14 for the remaining frequencies in
Table 2-52, making entries in the ac Coupled column.
34.Continue with “Agilent E4407B/E4408B Test Results.”
