Trends
Touch the TREND key in the INITIAL SETUP menu to access the Band
Frequency sub-menu. This sub-menu allows you to set the frequency ranges for
the five EEG frequency bands (DELTA, THETA, ALPHA, BETA1, BETA 2). Touch
the up or down arrow keys to change the upper frequency range for each band.
The lowest frequency for each band is set by the upper frequency of the band to
its left.
The SELECT TRENDS key allows you to choose the various trends to be
available for selection from the DISPLAY FORMAT, SETUP, and ARCHIVE
menus.
You can select any combination of MAG1, MAG2, FBR1, FBR2, SEF, PPF, MPF,
or EMG. You may not see all the trend options when you enter the trends sub-
menus. This is because you must select which trends appear in the trend sub-
menus. Select those trends you wish to have available by accessing the Initial
Setup menu, and choosing the trends you want.
Setting Trend Parameters
MAG1, MAG2, SEF, PPF, MPF
The sub-menu provides keys for changing the trend size and frequency band.
BAND
Trend parameters are calculated and displayed for the frequency bands set in this
menu. For example, magnitude in the alpha band can be calculated by selecting
the alpha frequency band for MAG1. You define the frequency range for each
band in the Initial Setup Menu.
Touch the appropriate keys to select the frequency band for each trend. If more
than one band is required, first touch the lowest frequency band (it will be
highlighted), then touch the highest (it will also be highlighted). The keys in-
between the lowest and highest frequency will be highlighted to indicate that these
bands have been selected.
The frequency band setting is displayed above the frequency band keys on the
message line as follows:
BAND x-y
x is the lowest frequency band, and y is the highest.
If only one band is selected, y is blank since the lowest and highest frequency
bands are the same.
SIZE
Trend size should be set using the SIZE ↑ or SIZE ↓ keys so that the trend
parameter lies close to the middle of the graph.
