42. Tracking Generator Absolute Amplitude and Vernier Accuracy: Agilent E4402B, E4403B,
E4404B, E4405B, E4407B, and E4408B (Option 1DN)
setting and subtracting the result from the Measured Power Level
for each Source Amplitude Setting in Table 2-93.
9. Record the vernier accuracy values from Table 2-93 as test record
entries (TR entries) 2 through 9 in the performance test record.
10.Copy the Absolute Vernier Accuracy values from Table 2-93 into
columns 2 and 3 of Table 2-94 on page 342, as indicated by the TR
entry numbers.
11.Calculate the Incremental Vernier Accuracy for each Source Vernier
Setting by subtracting the Absolute Vernier Accuracy value in
Column 3 of Table 2-94 from the Absolute Vernier Accuracy value in
Column 2. Record the result in Column 4 of Table 2-94 and in the
Performance Test Record as indicated by the TR entry number.
Example:
If the Absolute Vernier Accuracy for the −7 dB vernier setting is
0.23 dB (TR entry 6) and the Absolute Vernier Accuracy for the
−8 dB vernier setting is 0.08 dB (TR entry 7), the Incremental
Vernier Accuracy for the −8 dB vernier setting would be −0.15 dB
(−0.15 = 0.08 − 0.23).
