be –1.2 dB:
Measuring 300 MHz Second Harmonic Distortion
1. Connect the equipment as shown in Figure 2-50 using the 300 MHz
Low Pass Filter.
2. On the synthesized sweeper, press the following:
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)
Markers, Off
5. Adjust the synthesized sweeper power level until the power meter

1.2 dB 7.25 dBm 6.05 dBm()=
