Channel Parameter - allows you to change and select your desired channel/parameter
with which to create the harmonic graph/table. If you press this, the Change Parameter/
Channel window pops up showing groupings and arrangements of parameter/channel
combinations. One channel/parameter combination can be displayed at a time for the
spectrum graph, magnitude list, or phase angle list for the harmonics. See Harmonic
Channel/Parameter Selection.
Graph/Table - toggles between harmonic graph and tabular display. The screen
defaults to a graphical spectrum display, although you have the option to choose
between the graph or table form. The screen will show a spectral graph featuring the
amplitude of the harmonics relative to the fundamental frequency, as shown above. For
harmonic table display, see Harmonic Graph/Table.
Zoom - allows you to magnify and view harmonic graphs in detail. See Harmonic
Detail.
Scale - allows you to step through the vertical scale maximum value by 100%, 50%,
25% to 10%.
Options - allows you to select the vertical and horizontal measurement scale. The
percent magnitude of the first 127 harmonics are graphed relative to the fundamental.
See Harmonic Options.
