Harmonic Operation (Option 002 only)
The harmonic measurement mode allows you to measure the second or third harmonic as the
analyzer’s source sweeps fundamental frequencies above 16 MHz. The analyzer can make
harmonic measurements in any sweep type.

Figure 6-61. Typical Harmonic Mode Setup
Single-Channel Operation
You can view the second or third harmonic alone by using only one of the analyzer’s two
channels.
Dual-Channel Operation
To make the following types of measurements, uncouple channels 1 and 2, and switch on dual
channel.
The analyzer measures the fundamental on one channel while measuring the second or third
harmonic on the other channel.
The analyzer measures the second harmonic on one channel while measuring the third
harmonic on the other channel.

and 2. This is useful when you are using the to feature because you can change
fundamental power
and see
the resultant change in the harmonic power.
The analyzer shows the fundamental frequency value on the display. However, a marker in the
active
entry
area shows the harmonic frequency in addition to the fundamental. If you use
the harmonic mode, the annotation or appears on the left-hand side of the display.
The measured harmonic cannot not exceed the frequency limitations of the network analyzer’s
receiver.
