Screen Function Description
Y-Axis Graph Scaling Adjustment You can use the Up and Down arrows to manually adjust the y-
axis graph scaling on the spectrum. This lets you re-scale the
plot to get a closer look at low amplitude components:
• Up arrow decreases the Y-axis graph scale setting by ½ of its
current setting.
• Down arrow doubles the Y-axis graph scale setting.
Harmonic Markers The H key displays harmonic markers for the current cursor
position.
Harmonic markers rapidly locate integral orders in relation to
their fundamental (1X).
The H key cycles the three harmonic cursor modes:
• Simple, no harmonic cursors.
• Harmonic, displays the harmonics of the current cursor
position. The spectral cursor acts as the fundamental marker,
and is re-positioned.
• Fixed, the harmonics remain fixed and cursor can be moved
independently.
The default is Simple (off).
Peak cursor The P key lets you quickly jump the cursor to the next highest
peak to the right of the cursor.
Display Expansion The +/- key graphically expands or compresses the frequency
domain display range horizontally around the cursor position. It
reveals characteristics that may be hidden by the display mode
or by the resolution without changing data collection
parameters.
When using +/-, the spectrum’s fmax setting expands and the
spectrum reforms to the new fmax. You can repeat to continue
to expand up to the maximum resolution (based on the number
of lines of resolution for the spectrum), after which the function
switches to compression.
Dot (.) key immediately toggles the +/- key between display
expansion and compression.
