More Harmonics...
Opens a dialog for higher harmonics and arbitrary source and receive ports.
•
The Source port provides the stimulus signal at the fundamental frequency.
•
The receive port (Harmonics Measured at:) measures the signal at n times the fundamental
frequency where n is the Harmonic Order.
•
The Harmonic Order can be set in the range between 2 (2
nd
harmonic) and 100.
A label H<n> in the channel list indicates that the n
th
harmonic measurement is active.
In a frequency sweep all harmonics are displayed as a function of the stimulus frequency.
Use 2nd Harmonic Port1 to Port2 and 3rd Harmonic Port1 to Port2 to activate the measurement
of the second and third harmonics with a single menu command.

Freq Conv Off
Activates the measurement of the fundamental with the current port assignments and trace settings.
This effectively disables the harmonics measurement for the active channel.

Relative Measurement
Calculates the ratio of the selected harmonic to the fundamental (harmonic distortion factor) and
displays the result as a new trace. To avoid confusion between the original harmonic and the relative
measurement, the harmonic is hidden (invisible) but can be retrieved using the Trace Manager.
The relative trace belongs to a new channel. In the dB Mag trace format, the trace points are dB values,
after conversion to the lin Mag format, they correspond to the (dimensionless) ratio of two voltages:
