23. Frequency Response, Agilent E4402B and E4403B
Measuring Frequency Response Less Than or Equal to 100 kHz
1. Connect the equipment as shown in Figure 2-31.
Figure 2-31 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 has Option UKB, press Input/Output (or Input),
Coupling (DC). Then press SPAN, 100 Hz, BW/Avg, Res BW, 10 Hz, Video
BW, 10 Hz.
6. Adjust the function generator amplitude until the DVM reading is
–10 dBm ±0.1 dB.
7. Record the actual DVM reading in Table 2-46 as the DVM Amplitude
reading.
8. On the analyzer, press Peak Search (or Search), Marker, Delta.
9. Set the analyzer center frequency to the next frequency listed in
Table 2-46.
10.Set the function generator frequency to the next frequency listed in
