Presel Center.
13.Adjust the synthesized sweeper power level until the analyzer
marker delta (∆ Mkr1) amplitude reading is 0 dB ±0.05 dB.
14.Record the negative of the power meter reading in Table 2-52 as the
Flatness Relative to 50 MHz for dc coupled mode.
NOTE Record this power meter reading as the negative, or opposite polarity
from the measured value. For example, a measured value of –0.75 dB is
recorded as +0.75 dB; a measured value of +0.25 dB is recorded as
–0.25 dB.
If the analyzer is an Agilent E4407B without Option UKB, make all
entries in the dc coupled column.
15.Repeat step 10 through step 14 for frequencies up through
6.699 GHz in Table 2-52. On the analyzer, pressing FREQUENCY, ↑
will allow you to step through most of the frequencies. Similarly, on
the synthesized sweeper, pressing CW, ↑ will allow you to step
through most of the frequencies.
16.If the analyzer is an Agilent E4404B, continue with the next step.
Otherwise, continue with step 20.
17. On the analyzer, press Input/Output (or Input), Coupling (AC). This
sets the analyzer to ac coupled mode.
18.Repeat step 4 through step 15, making entries in the ac Coupled
column of Table 2-52.
19.Continue with “Agilent E4404B/E4405B Test Results” (for an
Agilent E4404B only). The following steps apply to the Agilent
E4405B, E4407B, and E4408B only.
20.Set the synthesized sweeper FREQ STEP to 400 MHz.
Set the analyzer center frequency step size to 400 MHz by manually
pressing FREQUENCY, CF Step, 400 MHz.
21.Repeat step 10 through step 14 for frequencies up through
13.199 GHz in Table 2-52.
22.If the analyzer is an Agilent E4405B, continue with the next step. If
the analyzer is an Agilent E4407B or E4408B, continue with step 27.
23. On the analyzer, press Input/Output (or Input), Coupling (AC). This
sets the analyzer to ac coupled mode.
24.Repeat step 4 through step 15, making entries in the ac Coupled
column of Table 2-52.
25.Set the synthesized sweeper FREQ STEP to 400 MHz.
Set the analyzer center frequency step size to 400 MHz by pressing
FREQUENCY, CF Step, 400 MHz.
