Harmonic Measurement Accuracy
1. On the analyzer, press System, HARMONIC MEAS, SECOND, then press
Sweep Setup, CW FREQ, 20, M/µ.
2. Set the external source for CW operation at 40 MHz (the second
harmonic).
3. On the analyzer, press TRIGGER MENU, SINGLE. Record the “mean”
reading of the marker in the performance test record under “Network
Analyzer Reading” for the second harmonic (40 MHz).
4. On the power meter, set the cal factor appropriate for the frequency of
the external source. Record the power meter reading in the
performance test record under “Power Meter Meas” for the second
harmonic (40 MHz).
5. Set the external source for CW operation at 60 MHz (third harmonic).
6. On the analyzer, press System, HARMONIC MEAS, THIRD, then press
Sweep Setup, TRIGGER MENU, SINGLE. Record the “mean” reading of
the marker in the performance test record under “Network Analyzer
Reading” for the third harmonic (60 MHz).
7. On the power meter, set the cal factor appropriate for the frequency of
the external source. Record the power meter reading on the
performance test record under “Power Meter Meas” for the third
harmonic (60 MHz).
8. Repeat steps 4 through 7 for the second and third harmonics of the
other analyzer frequencies.
In Case of Difficulty
1. Check all connections.
2. Ensure that correct power meter cal factors were used.
3. Refer to Chapter 3, “Theory of Operation and Troubleshooting.”
