Performance Verification Tests
31. Spurious Responses: Agilent E4402B and E4403B
17.Record the power meter reading in Table 2-73 as the 900 MHz power
meter reading.
18.On the synthesized sweeper, press CW, 1.8 GHz.
19.On the analyzer, press the following:
FREQUENCY, Center Freq, 1.8 GHz
Peak Search (or Search)
AMPLITUDE
20.On the analyzer, press Peak Search (or Search).
21.Adjust the synthesized sweeper power level until the marker delta
(∆ Mkr1) amplitude reads 0 dB ±0.1 dB.
22.Enter the power sensor 2 GHz calibration factor into the power
meter.
23.Record the power meter reading in Table 2-73 as the 1.8 GHz power
meter reading.
24.On the analyzer, press Marker, Off.
25.Subtract the power meter reading at 1.8 GHz from the power meter
reading at 900 MHz. Record this difference as the 900 MHz
Frequency Response Error in Table 2-73. For example, if the power
meter reading at 1.8 GHz is –6.35 dBm and the power meter reading
at 900 MHz is –7.05 dBm, the 900 MHz Frequency Response Error
would be –0.7 dB:
Measuring the 300 MHz Second Harmonic Distortion
1. Connect the equipment as shown in Figure 2-48 using the 300 MHz
Low Pass Filter.
2. On the synthesized sweeper, press:
CW, 300 MHz
POWER LEVEL, –10 dBm
3. Enter the power sensor 300 MHz calibration factor into the power
meter.
4. On the analyzer, press the following:
FREQUENCY, Center Freq, 300 MHz
SPAN, 100 kHz
AMPLITUDE, Ref Level, –10 dBm
AMPLITUDE, Attenuation, 10 dB (Man)
BW/Avg, Res BW 1 kHz (Man)
Video BW, 1 kHz (Man)
