Larson Davis System 824 - Spatial Avg Check Menu

10-36 824 Reference Manual 11/8/00
Any display which shows a spectrum
can be averaged using the “+Aver-
age” item on its check menu.
Each display that can show a spectrum has a check menu
item, “+Average”, that, when selected, will prompt the user
“Add to Average?”. It then offers the following choices:
•
Yes
-averages the spectrum being viewed to those previ-
ously averaged.
There is effectively no limit on the
number of spectra that may be aver-
aged.
•
No
- the spectrum is not averaged into the previous aver-
age but the spatial average display is shown
•
Cancel
- nothing happens and the previous display is
shown
Once, one or more spectra have been averaged, they can be
stored into the “Avg History”.
