Sweep graph
●
"Next Pixel "
Selecting the "Next Pixel" button moves the cursor by one pixel in the graphic with
every increment. If there is not a measured value at every pixel in the graphical dis-
play (because only a few measurement points were recorded relative to the size of
the displayed graph), the cursor value is interpolated linearly at the pixels between
the measured values. If the number of recorded measurement points in the graph
is greater than the number of pixels available for display, the largest measured
value in each case is displayed at the corresponding pixel with X and Y value.
●
"Next Step "
Selecting the "Next Step" button moves the cursor to the next measured value with
every increment. The cursor is therefore moved in smaller or larger steps depend-
ing on the number of measurement points. If the graph is displayed relatively small
or the number of recorded measured values displayed is greater than the number
of pixels available in the graphical field, the cursor sometimes does not appear to
move (it remains on the same pixel). However, the associated display fields always
show the currently selected measurement point with X and Y-value.
●
"Next Peak "
Selecting the "Next Peak" button moves the cursor to the next measured peak with
every increment.
FFT Graph
●
"Next Pixel "
Selecting the "Next Pixel" button moves the cursor by one pixel in the graphic with
every increment.
With FFT analyses, the number of recorded measurement points (bins) is usually
much greater than the number of pixels available for display in the graph; the cur-
sor then indicates the bin with the largest measured value at the pixel in question
and displays this bin with its X and Y-values.
●
"Next Bin "
Selecting the "Next Bin" button moves the cursor to the next measured bin with
every increment.
Since with FFT analyses the number of recorded measurement points (bins) is
usually much greater than the number of pixels available for display, the cursor
sometimes does not appear to move (it remains on the same pixel). However, the
associated display fields always show the currently selected measurement point
with X and Y-value.
●
"Next Peak "
Selecting the "Next Peak" button moves the cursor to the next measured peak with
every increment.
●
"Next Harmonic "
Selecting the "Next Harmonic" button moves the cursor to the next marked har-
monic with every increment.
This button is also available if the harmonic marker is not active (see the next sec-
tion, Operating the markers). In this case, the button activates the harmonic
marker.
