Modifying the Stimulus
When the stimulus is de
fi
ned, a complete list of signal parameters and variables are added to
the BioSigRZ
fi
le. During stimulus presentation, the values of the variables change as a
function of the SGI. This is called the stimulus schedule.
You may wish to present a subset of the current stimulus schedule. Both the stimulus schedule
and the variable de
fi
nitions can be modi
fi
ed in BioSigRZ. To do so, display the stimulus
schedule (as below) then select the SGIs to be included in the subset for presentation.
To view the current stimulus schedule:
Select
Modify Schedule
from the
Operations
menu.
Or
select
SigGen Variables
from the
Setup
menu.
Or
click the
Modify Schedule
button.
The
SigGen Variable Control
dialog displays the current stimulus schedule. Variable values are
shown for each SGI. Select SGIs to include in signal presentation by using standard Windows
