Performance Verification Tests
26. Frequency Response (Preamp On): Agilent E4402B
Test Results
1. Record the most positive number from the Flatness Relative to 50
MHz column of Table 2-61 as the Maximum Response for Band 0 in
Table 2-62.
2. Record the most negative number from the Flatness Relative to 50
MHz column of Table 2-61 as the Minimum Response for Band 0 in
Table 2-62.
3. For Band 0 in Table 2-62, 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 E4402B with a serial number greater
than or equal to US39441006 then continue with the next step.
Otherwise, transfer the values entered in Table 2-62 to the test
record in this guide; the frequency response test is now complete.
5. Note the most positive number from the Flatness Relative to 50 MHz
column of Table 2-61 for frequencies between 800 MHz and 1.0 GHz.
Record this number in Table 2-62 as the Maximum Response for
Band 0A.
6. Note the most negative number from the Flatness Relative to 50
MHz column of Table 2-61 for frequencies between 800 MHz and 1.0
GHz. Record this number in Table 2-62 as the Minimum Response
for Band 0A.
7. For Band 0A in Table 2-62, subtract the Minimum Response value
from the Maximum Response value and record the result in the
Peak-to-Peak Response column.
8. Note the most positive number from the Flatness Relative to 50 MHz
column of Table 2-61 for frequencies between 1.7 GHz and 2.0 GHz.
Record this number in Table 2-62 as the Maximum Response for
Band 0B.
