●
Comments introduced by "#" are allowed.
●
If a limit is not provided for a harmonic, the harmonic is displayed and its results
are included in the export, but not in the limit check.
●
The fundamental is always displayed and need not be included in the list.

6.3.6.2 Export File Format for Harmonic Results
The harmonic results export file format is similar to a waveform export file; it is also
stored in CSV format. You can convert the comma-separated text to columns (see
Chapter 12.4.3.3, "Converting CSV to Excel Files", on page 276).
The harmonics results file contains some general header data and then a set of result
data for each harmonic. A maximum of 64 results can be provided, but the actual num-
ber of harmonics may be restricted (see "Limits, Loaded File" on page 139). Each set
of data contains the results for a specific harmonic in each input channel.
