b. Connect a 75 Ω termination to the RF OUT 75 Ω.
Measurement Sequence
The following option-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 2-81 Table 2-82,
Table 2-83 or Table 2-84. 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 the appropriate table.
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 the appropriate table.
4. If the minimum RBW of the analyzer is 100 Hz or 10 Hz and Option
1DN or 1DQ (1.5 GHz Tracking Generator) is installed, perform
those procedures listed in Subset A in the appropriate table.
5. If the minimum RBW of the analyzer is 10 Hz and both Option 1DS
(RF Preamplifier) and Option 1DN or 1DQ (1.5 GHz Tracking
Generator) are installed, also perform those procedures listed in
Subset B in the appropriate table.
6. If the minimum RBW of the analyzer is 100 Hz or 10 Hz, also
