Performance Verification Tests
44. Tracking Generator Level Flatness: Agilent E4402B, E4403B, E4404B, E4405B, E4407B,
and E4408B (Option 1DN)
2. Set the analyzer resolution bandwidth to 10 kHz by pressing
BW/Avg, Res BW, 10 kHz.
Repeat step 3 through step 7 for each Center Frequency value in
Table 2-98.
3. Set the analyzer center frequency to 9 kHz, by pressing FREQUENCY,
9 kHz.
4. Press Single.
5. Record the DVM readout in Table 2-98.
6. Subtract the 100 kHz Level Flatness readout in Table 2-97 from the
100 kHz DVM Readout in Table 2-98 and record as the DVM Offset
at 100 kHz.
DVM Offset at 100 kHz ___________ dB
For example, if the Level Flatness reading from Table 2-97 is
0.7 dB and the DVM Readout from Table 2-98 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 2-98 and record as the Corrected Level
Flatness in Column 3.
For example, if the DVM Readout from Table 2-98 is 0.22 dBm,
and the DVM Offset is −1.23 dB, the Corrected Level Flatness
would be −1.01 dB.
8. Press System, Alignments, Auto Align, All.
Set to 50 Ω impedance SMATH 10a
Set to dBm MATH 5a
Set to Synchronous SETACV 3a
Sub-sampled mode
a. To set the Agilent 3458A multimeter functions from the
front panel, press the blue shift key, then Recall State (T)
key. Use the ⇑ (up) and ⇓ (down) arrows to select the
appropriate function, then enter the value from the
numeric keypad and press enter.
