Performance Verification Tests
37. Displayed Average Noise Level: Agilent E4404B and E4405B
17.If the analyzer has Option 1DN, 50 Ω tracking generator, do the
following:
a. On the analyzer, press BW/Avg, Res BW, 1 kHz.
b. Press Source, Amplitude, 0 dBm.
c. Connect a 50 Ω termination to the RF OUT 50 Ω.
Measurement Sequence
The following model-specific DANL Measurement Sequence tables list
the procedures to be performed and the parameters to be used in each
procedure. Also listed in the tables are test record entry numbers for
recording the results in the performance verification test record.
1. Perform all of the following steps (through step 7) that apply to your
analyzer using the appropriate subsets in Table 2-87 or Table 2-88.
Then record the display line amplitude setting as the indicated Test
Record entry in the performance verification test record.
2. If the minimum RBW of the analyzer is 1 kHz, perform those
procedures listed as Subset A in Table 2-87 or Table 2-88.
3. If the minimum RBW of the analyzer is 1 kHz and Option 1DS (RF
Preamplifier) is installed, also perform those procedures listed in
Subset B in Table 2-87 or Table 2-88.
4. If the minimum RBW of the analyzer is 10 Hz and Option 1DN (3.0
GHz Tracking Generator) is installed, perform those procedures
listed in Subset A in Table 2-87 or Table 2-88.
5. If the minimum RBW of the analyzer is 10 Hz and both Option 1DS
(RF Preamplifier) and Option 1DN (3.0 GHz Tracking Generator)
are installed, also perform those procedures listed in Subset B in
Table 2-87 or Table 2-88.
6. If the minimum RBW of the analyzer is 10 Hz, also perform those
procedures listed in Subset C in Table 2-87 or Table 2-88.
7. If the minimum RBW of the analyzer is 10 Hz and Option 1DS (RF
Preamplifier) is installed, also perform those procedures listed in
Subset D in Table 2-87 or Table 2-88.
8. After performing all applicable DANL measurement procedures,
continue with Remove Reference Level Offset.
