Performance Verification Tests
24. Frequency Response, Agilent E4404B, E4405B, E4407B, and E4408B
Measuring Frequency Response Less Than or Equal to 100 kHz
NOTE Do not perform this procedure for Agilent E4407B analyzers having
Option UKB in ac coupled mode.
1. Connect the equipment as shown in Figure 2-34.
Figure 2-34 Frequency Response Test Setup, ≤100 kHz
2. Set the function generator controls as follows:
FREQUENCY, 100 kHz
AMPLITUDE, –4 dBm
Amptd Increment, 0.05 dB
3. Set the DVM as follows:
4. On the analyzer, press FREQUENCY, 100 kHz.
5. If the analyzer under test is an Agilent E4407B with Option UKB,
E4404B or E4405B, press Input/Output (or Input), Coupling (DC).
6. If the analyzer under test has Option UKB then press SPAN, 100 Hz,
BW/Avg, Res BW, 10 Hz, Video BW, 10 Hz.
7. Adjust the function generator amplitude until the DVM reading is
–10 dBm ±0.1 dB.
8. Record the actual DVM reading in Table 2-51 as the DVM Amplitude
reading.
