Performance Verification Tests
42. Tracking Generator Absolute Amplitude and Vernier Accuracy: Agilent E4402B, E4403B,
E4404B, E4405B, E4407B, and E4408B (Option 1DN)
Setup
4. Read the power level displayed on the power meter, add 20 dB, and
record the result as Test Record entry 1 of the performance
verification test record as the Absolute Amplitude Accuracy.
Absolute Amplitude Accuracy at 50 MHz = ___________dB
5. Set the power meter to dB relative mode as described in the power
meter operation manual so that the readout is in power level relative
to the power level at 50 MHz (press Rel/Offset, Rel).
6. Press Single on the analyzer. At each setting, record the power level
displayed on the power meter in Table 2-93.
7. Set the source amplitude to the settings indicated in Table 2-93.
8. Calculate the Vernier Accuracy by adding 4 dB to the Source Vernier
