Reviewing Spectra Data
The Available Data window shows the different types of data. If you collected that type of
data for this point, you can view it by selecting the data type.
Use the arrow keys to highlight Spectra (FFT), then press <SELECT>. The dataPAC
displays a spectrum if it is available. The dataPAC displays the measurement with the
default cursor type, selected in the Setup Utility. See “Setting Up FFT Display Options” on
page 41 for more information.
For the dataPAC 1500, if there is an asterisk ‘*’ proceeding the amplitude and frequency
readouts, then the data for this cursor location is being computed, instead of the raw
spectrum data.
Using the Cursors with a Spectrum
Cursors are available to precisely identify numerical values in a spectrum measurement.
Cursors are drawn as either dashed or dotted lines perpendicular to their associated axis.
You can use the cursor to identify the amplitude and frequency of peaks in a spectrum. The
value of the cursor location is displayed at the top of the screen. When more than one
spectral bin occupies the display position of the active cursor, the values displayed
correspond to the bin with the highest amplitude at that display position.
Press the arrow keys to activate the cursor and move it along the spectrum.
