 In the relative measurement, the nth harmonic of the stimulus signal is divided by 1st harmonic
(fundamental) received from the DUT. The result corresponds to the nth harmonic distortion
factor.
Harmonic distortion measurements can be performed irrespective of the sweep type: A frequency sweep
yields the harmonics as a function of the frequency, a power sweep yields the power-dependent
harmonics at fixed frequency.
 2nd Harmonic Port 1 to Port 2... activates the measurement of the second harmonic at port 2 with
port 1 as source port.
 3rd Harmonic Port 1 to Port 2... activates the measurement of the third harmonic at port 2 with
port 1 as source port.
 More Harmonics opens a dialog for higher harmonics and arbitrary source and receive ports.
 Reset Frequency Conversion activates the measurement of the fundamental with the current port
assignments and trace settings.
 Relative Measurement calculates the ratio of the selected harmonic to the fundamental and
displays the result as a new trace.
 Harmonic Power Cal... opens a dialog to perform a power calibration of the signal source and of
the receiver.
The result of several harmonic measurements can be displayed in a common diagram area (see
Traces, Channels and Diagram Areas). To make the comparison of the fundamental trace and the
harmonics easier the stimulus axis for frequency sweeps remains unchanged, and all fundamentals are
displayed as a function of the stimulus frequency (rather than the harmonic frequencies).
A warning Frequency out of range. Please check dialog Mode: Port Configuration. is displayed if one of
the harmonic frequencies to be measured exceeds the frequency range of the analyzer. The harmonic
traces are truncated at the maximum receiver frequency.
The harmonic measurement mode is cancelled if the channel settings (e.g. port assignments, port
frequencies) are no longer compatible with the selected harmonic.
2nd Harmonic Port1 to Port2
Activates the measurement of the second harmonic at port 2 with port 1 as source port. The active trace
