Performance Verification Tests
32. Spurious Responses: Agilent E4404B, E4405B, E4407B, and E4408B
would be –1.2 dB:
Measuring 3.1 GHz Frequency Response Error
1. On the synthesized sweeper, press the following:
CW, 3.1 GHz
POWER LEVEL, 0dBm
2. On the analyzer, press FREQUENCY, 3.1 GHz.
3. Enter the power sensor 3 GHz calibration factor into the power
meter.
4. On the analyzer, press the following:
Marker, Off
Peak Search (or Search)
AMPLITUDE
Presel Center
5. On the analyzer, press Peak Search (or Search), Marker, Delta.
6. Record the power meter reading in Table 2-76 as the 3.1 GHz power
meter reading.
7. On the synthesized sweeper, press CW, 6.2 GHz.
8. On the analyzer, press the following:
FREQUENCY, 6.2 GHz
Peak Search (or Search)
AMPLITUDE
Presel Center
9. On the analyzer, press Peak Search (or Search).
10.Adjust the synthesized sweeper power level until the marker delta
(∆ Mkr1) amplitude reads 0 dB ±0.1 dB.
11.Enter the power sensor 6 GHz calibration factor into the power
meter.
12.Record the power meter reading in Table 2-76 as the 6.2 GHz power
meter reading.
13.On the analyzer, press Marker, Off.
14.Subtract the power meter reading at 6.2 GHz from the power meter
reading at 3.1 GHz. Record this difference as the 3.1 GHz Frequency
Response Error in Table 2-76. For example, if the power meter
reading at 6.2 GHz is –6.05 dBm and the power meter reading at
3.1 GHz is –7.25 dBm, the 3.1 GHz Frequency Response Error would
