Making Harmonic Measurements
Perform the following steps to display the absolute power of the fundamental and second harmonic in dBm.
1. Press to measure the power for the fundamental
frequencies.
2. Press to measure the power for the harmonic frequencies.
3. Set the start frequency to a value greater than 16 MHz.
4. Press and select . Uncoupling the channels allows you to
have the separate sweeps necessary for measuring the fundamental and harmonic frequencies.
5. Press and select . Coupling the channel power allows you
to maintain the same fundamental frequency power level for both channels.
6. Press and set the power level for both channels.
7. Press and select .
8. Press and position marker to desired frequency.
9. Press . You can view both the fundamental power and
harmonic power levels at the same time. (Refer to Figure 1-45.)
