23. Frequency Response, Agilent E4402B and E4403B
Table 2-46. Frequencies less than 9 kHz only apply to analyzers with
Option UKB.
11.On the analyzer, press Peak Search (or Search).
12.Adjust the function generator amplitude until the marker delta (
Mkr1) amplitude reads 0 dB ±0.05 dB.
13.Record the DVM reading in Table 2-46 as the DVM Amplitude
reading.
14.Repeat step 9 through step 13 for each frequency setting listed in
Table 2-46.
15.For each of the frequencies in Table 2-46, subtract the DVM
Amplitude from the DVM Amplitude at 100 kHz recorded in step 7.
Record the result as the Response Relative to 100 kHz in Table 2-46.
16.From Table 2-45, note the Flatness Relative to 50 MHz for the
100 kHz frequency. Record this below as the 100 kHz Error Relative
to 50 MHz:
100 kHz Error Relative to 50 MHz =__________ dB
17.Add the 100 kHz Error Relative to 50 MHz that was recorded in
step 16 above to each of the Response Relative to 100 kHz entries in
Table 2-46. Record the results as the Response Relative to 50 MHz in
Table 2-46.
