Performance Verification Tests
24. Frequency Response, Agilent E4404B, E4405B, E4407B, and E4408B
Measuring Frequency Response, >3 GHz
1. Replace the Channel B power sensor with the microwave power
sensor. Zero and calibrate the power sensor and power meter in log
mode. Enter the 50 MHz calibration factor of the power sensor into
the power meter.
2. Connect the equipment as shown in Figure 2-35.
Figure 2-35 Frequency Response Test Setup, >3 GHz
3. If the analyzer is an Agilent E4407B with Option UKB, E4404B or
E4405B, then press Input/Output (or Input), Coupling (DC). This sets
the analyzer to dc coupled mode.
4. On the analyzer, press FREQUENCY, 50 MHz, CF Step 250 MHz.
5. Set the synthesized sweeper CW frequency to 50 MHz and
FREQ STEP to 250 MHz.
6. Adjust the synthesized sweeper power level for a power meter
reading of –10 dBm ±0.05 dB.
7. On the analyzer, press Peak Search (or Search).
8. On the analyzer, press Marker, Delta.
9. Activate the dB relative mode on the power meter. Power meter
readings will now be displayed relative to the power meter reading
at 50 MHz.
10.Set the synthesized sweeper CW frequency to the next frequency
listed in Table 2-52.
11.Enter the appropriate power sensor calibration factor into the power
meter.
12.On the analyzer, press Peak Search (or Search), Amplitude,
