Performance Verification Tests
32. Spurious Responses: Agilent E4404B, E4405B, E4407B, and E4408B
Part 2: Second Harmonic Distortion
1. Zero and calibrate the power meter and microwave power sensor.
Enter the power sensor 300 MHz calibration factor into the power
meter.
Measuring the Noise Level at 6.2 GHz
2. Remove any cables or adapters from the analyzer Input.
3. Press Preset on the analyzer. Press the Factory Preset softkey, if it is
displayed. Set the controls as follows:
FREQUENCY, 6.2 GHz
SPAN, 0Hz
AMPLITUDE, Ref Level, –40 dBm
AMPLITUDE, Attenuation, 10 dB
BW/Avg, Res BW 1 kHz
Video BW, 30 Hz
Sweep, Sweep time, 5 s
4. Wait until “VAvg 10” is displayed along the left side of the display.
5. Press Peak Search (or Search) and record the marker amplitude
reading as the 6.2 GHz Noise Level in Table 2-76.
Measuring 300 MHz Frequency Response Error
1. Press Preset on the analyzer. Press the Factory Preset softkey, if it is
displayed. Set the controls as follows:
FREQUENCY, 300 MHz
SPAN, 10 MHz
2. Connect the equipment as shown in Figure 2-50, with the output of
the synthesized sweeper connected to the power splitter input and
the power splitter outputs connected to the analyzer and power
sensor.
