Performance Verification Tests
27. Frequency Response (Preamp On): Agilent E4404B, E4405B, and E4407B
Test Results
1. Record the most positive number from the Flatness Relative to
50 MHz (dc) column of Table 2-64 as the Maximum Response for
Band 0 in Table 2-65.
2. Record the most negative number from the Flatness Relative to
50 MHz (dc) column of Table 2-64 as the Minimum Response for
Band 0 in Table 2-65.
3. For Band 0 in Table 2-65, subtract the Minimum Response value
from the Maximum Response value and record the result in the
Peak-to-Peak Response column.
4. If the analyzer is an Agilent E4404B with a serial number greater
than or equal to US39440498 then continue with step 8. Otherwise,
transfer the values entered in Table 2-65 to the test record in this
guide; the frequency response test is now complete.
