Performance Verification Tests
27. Frequency Response (Preamp On): Agilent E4404B, E4405B, and E4407B
5. On the analyzer, press Peak Search (or Search).
6. Adjust the source power level to obtain a marker amplitude reading
on the analyzer of –32.00 dBm ±0.2 dB.
7. Record the current Channel B power reading in Table 2-64 as the
Current Channel B Reading for ac or dc coupling, as appropriate. If
the analyzer does not have switchable ac/dc coupling, enter all data
into the dc columns.
8. Record the marker (Mkr1) amplitude reading in Table 2-64.
9. Set the source to the next frequency listed in Table 2-64.
10.Set the analyzer center frequency to the next frequency listed in
Table 2-64.
11.On the analyzer, press Peak Search (or Search).
12.Adjust the source power level to obtain a marker amplitude reading
on the analyzer of –32.00 dBm ±0.2 dB.
13.Record the current Channel B power reading in Table 2-64 as the
current Channel B reading in the ac or dc column, as appropriate.
14.Record the marker (Mkr1) amplitude reading in Table 2-64.
15.Repeat step 9 through step 14 for each remaining frequency in
Table 2-64.
16.If the analyzer is an Agilent E4407B with Option UKB and is being
tested in ac coupled mode, continue with step 26. These analyzers
are specified only down to 10 MHz in ac coupled mode.
17.Replace the synthesized sweeper with the function generator.
18.Set the function generator amplitude to 112 mV rms (–6 dBm, or
–12 dBm plus nominal power splitter insertion loss).
19.Set the function generator frequency to 1 MHz.
20.Set the analyzer center frequency to 1 MHz.
21.On the analyzer, press Peak Search (or Search).
22.Adjust the function generator amplitude to obtain a marker
amplitude reading of –00 dBm ±0.2 dB.
23.Record the current Channel B power reading in Table 2-64 as the
current Channel B reading.
24.Record the analyzer marker (Mkr1) amplitude reading in Table 2-64
as marker (Mkr1) amplitude.
25.Repeat step 19 through step 24 for frequencies between 1 MHz and
10 MHz.
26.Copy the Splitter Tracking Error values from Table 2-63 into
Table 2-64.
