10.10.2. Use for DFT Chart selection fine-tuning

Use for

DFT fine

tuning

Select a Waveform chart with a waveform event visible, and select the command

Insert > DFT Chart from the toolbar or from the menu (or right-click on the chart

and select Insert DFT Chart). The newly created DFT is now connected to the

waveform chart and will display the DFT analysis for the current event range.

Now activate the Area Marker Tool and select a range of waveform cycles. When

you release the pointer button, you will see the DFT-Chart updates. It will also

show the DFT contents of the selected waveform range. The Area Marker selection

in the waveform chart overrides the current event range for DFT calculations.

When selecting an area in a Waveforms/Details chart, the area marker will adjust

itself to the nearest full waveform cycle(s), unless you have selected the Free

Selection option (described below). This is done so you can see the true range used

for DFT calculations. This checkbox is also available in the upper right corner of

the waveform chart along with information about selected waveform sample points.

10.10.3. Use for Phasor selection fine-tuning

Use for

Phasor fine

tuning

If you have a Phasor located within a frame of Waveform chart, the phasor is

connected to that chart. Normally the phasor shows the phase angles for the

selected event, but with an Area Marker selection in that Waveform Chart, this

behavior is overridden and the Area Marker rules the calculation of the Phasor.

10.10.4. Use for Statistics Table selection fine-tuning

Use for

statistics

tables fine

tuning

If you add a Statistics table to the Timeplot Chart (locate it within the frame of the

chart), it normally displays information gathered within the borders of the current

X-axis zoom. However with an Area Marker selection in that Timeplot Chart, this

behavior is overridden and the Area Marker rules the calculation of the Statistics

table.
