Performance Verification Tests
14. Reference Level Accuracy: Agilent E4401B and E4411B
Linear Scale, Digital Bandwidths, Option 1DR
NOTE If the analyzer is an E4401B that is not equipped with Option 1DR
(narrow resolution bandwidths) or an E4411B (with or without Option
1DR), continue with the next section (Post-test Instrument
Restoration).
1. On the analyzer, press the following keys:
SPAN, 150 Hz
BW/Avg, 10 Hz
Video BW, 1 Hz
2. Set the 1 dB step attenuator to place the signal peak 1 to 3 divisions
below the reference level.
3. On the analyzer, press the following keys:
Single
Peak Search
(or Search)
Marker, Delta
4. Set the 10 dB step attenuator and analyzer reference level according
to Column 1 and Column 4 of Table 2-23. At each setting, do the
following:
