Calculator
With the calculator users can perform arithmetic and logical operations on data from one or
several channels in all analysis files. The resulting data can then be assigned to a new channel.
To assign an expression to a channel, always use the assignment operator (:=). This operator
and other commonly used operators are already available in the pocket computer
keypad integrated in the channel calculator dialog. Existing channels can be selected with a
double-click.
