The gain of the screen will increase by a power of 2 each time you press this key. This feature may
be selected directly from the tool bar. Note that if you are displaying both the Single and Multiple
Window Displays, you can select either screen by clicking the mouse on the gray horizontal bar at
the top of the display. It will change to blue (or other user selected color) when active. The scaling
options will be applied to the active display. The screen amplitude affects only the display, and it
does not affect values stored to disk.
Decrease Scaling (Single and Multiple Window and Frequency displays)
The Decrease Scaling button will decrease the scale of the amplitude in the selected screen display.
This feature may be selected directly from the tool bar.
Autoscale (Single and Multiple Window and Frequency displays)
The Autoscale function amatically sets the amplitude scaling to the largest and smallest voltages
detected from any channel.
Next Display Page
This option allows you to step through electrode display pages that are created when you indicate
that you are recording from more than 32 channels, or if you have created additional display pages
in the Individual Channel Settings section. Clicking on this field, or on the corresponding icon on the
tool bar, will cycle forward through the pages you have created.
Previous Display Page
Clicking on this field, or the corresponding icon on the tool bar, will allow you to cycle backward
through the electrode display fields, or if you have created additional display pages in the Individual
Channel Settings section. The Next and Previous Display Page options will not be accessible if you
have not created additional display pages.
Baseline Corrections
The baseline button is used to center the baseline of waveforms graphically with their associated
labels located on the left-hand side of the screen. This operation is performed each time the waveforms begin drawing from the left-hand side of the screen and has no effect on the actual data. This
option is implemented as a toggle. The baseline option will toggle on and off each time you press the
field, or select the corresponding icon from the tool bar. Baseline is particularly useful with D.C.
recordings in which the D.C. values will cause a large offset of the starting screen location.
Invert Polarity on Display
The Invert option will invert the polarity of the signals on the display screens so that positive voltage
is plotted up. This option is most easily accessed from the corresponding icon on the Toolbar. (The
default setting is negative voltage up).
Perform DC Correction (SynAmps only)
Performs single DC correction with each use to remove DC components (will center signals at the
baseline). DC corrections can be performed manually by clicking the icon (see below), or automatically when you Enable the "DC Correction option (see AC/DC section above). When a DC
correction occurs, you will see a DCC event marker at the bottom of the Single Window display
(along with the stimulus and response events). The DC corrections will be stored in the data file,
and are treated as events in the file.
