24. Frequency Response, Agilent E4404B, E4405B, E4407B, and E4408B
Agilent E4407B/E4408B Test Results
Perform the following steps to verify the frequency response of the
analyzer.
1. Enter the most positive number from the Flatness Relative to
50 MHz (dc) column of Table 2-50:
____________ dB
2. Enter the most positive number from the Response Relative to
50 MHz column of Table 2-51:
____________ dB
3. Record the most positive of numbers from step 1 and step 2 in Table
2-55 as the Maximum Response for Band 0.
4. Enter the most negative number from the Flatness Relative to
50 MHz (dc) column of Table 2-50:
____________ dB
5. Enter the most negative number from the Response Relative to
50 MHz column of Table 2-51:
____________ dB
6. Record the most negative of numbers from step 4 and step 5 in Table
2-55 as the Minimum Response for Band 0.
7. For Band 0 in Table 2-55, subtract the Minimum Response value
from the Maximum Response value and record the result in the
Peak-to-Peak Response column.
8. If the analyzer is an Agilent E4408B, an E4407B with Option UKB,
or is an E4407B with a serial number less than US39440871, then
