Performance Verification Tests
38. Displayed Average Noise Level: Agilent E4407B and E4408B
17.On the analyzer, press Input, Amptd Ref Out (Off), then AMPLITUDE,
More, Ref Lvl Offst, and enter the value recorded in step 10.
18.Connect the 50 Ω termination to the analyzer input as shown in
Figure 2-56.
19.Disconnect the BNC cable and adapter from the AMPTD REF OUT
and the 50 Ω Input.
20.If the analyzer is equipped with 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 table lists
the procedures to be performed and the parameters to be used in each
procedure. Also listed in the table 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 2-89 (E4407B) or
Table 2-90 (E4408B). 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 2-89 or Table 2-90.
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 2-89.
4. If the minimum RBW of the analyzer is 100 Hz or 10 Hz and Option
1DN (3.0 GHz Tracking Generator) is installed, perform those
procedures listed in Subset A in Table 2-89 or Table 2-90.
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 2-89.
6. If the minimum RBW of the analyzer is 100 Hz or 10 Hz, also
perform those procedures listed in Subset C in Table 2-89 or Table
2-90.
7. If the minimum RBW of the analyzer is 10 Hz and Option 1DS (RF
Preamplifier) is installed, also perform those procedures listed in
