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.

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

while measuring the second or third harmonic in dBc on channel 2.

using the ~~~~~~~~~~~~ featme, the analyzer couples power between channels 1

and 2. This is useful when you are using the D2/Dl to D2 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 H=2 or H=3 appears on the left-hand side of the display. The measured harmonic cannot not exceed the frequency limitations of the network analyzer’s receiver.
