Harmonic Operation (Option 002 Only) - Agilent Technologies 8753ET User Manual

Harmonic Operation (Option 002 Only)

The analyzer's harmonic menu can be accessed by pressing
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.
Typical Test Setup
Figure 7-48 Typical Harmonic Mode Test 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.
• Using the
COUPLE PWR ON off
channel 1 while measuring the second or third harmonic in dBc on channel 2.
• Using the
COUPLE PWR ON off
channels 1 and 2. This is useful when you are using the D2/D1 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.
