Performance Verification Tests
43. Tracking Generator Level Flatness: Agilent E4401B and E4411B (Option 1DN or 1DQ)
4. Press Single.
5. Record the DVM readout in Table 2-96.
6. Subtract the 100 kHz Level Flatness readout in Table 2-95 from the
100 kHz DVM Readout in Table 2-96 and record as the DVM Offset
at 100 kHz.
DVM Offset at 100 kHz ___________ dB
For example, if the Level Flatness reading from Table 2-95 is
0.7 dB and the DVM Readout from Table 2-96 is −0.53 dBm, the
DVM offset would be −1.23 dB.
7. Add the DVM Offset at 100 kHz from step 6, above, to each of the
DVM Readouts in Table 2-96 and record as the Corrected Level
Flatness in Column 3.
For example, if the DVM Readout from Table 2-96 is 0.22 dBm,
and the DVM Offset is −1.23 dB, the Corrected Level Flatness
would be −1.01 dB.
8. For 50 Ω tracking generators only, locate the most positive Level
Flatness reading in Table 2-95 and Table 2-96 for frequencies
<1 MHz and enter this value as Test Record entry 1 of the
performance verification test record.
9. For 50 Ω tracking generators only, locate the most negative Level
Flatness reading in Table 2-95 and Table 2-96 for frequencies
<1 MHz and enter this value as Test Record entry 2 of the
DVM Offset DVM Readout= Level Flatness–
Corrected Level Flatness DVM= DVM Offset+
