Add a calculated Boolean channel to produce a high or low Boolean digital signal based
on an analog or digital channel.
On the Channel Specification toolbar, select .
A calculated channel appears in the Channel
Specification under its host system.
Configure the calculated channel.
After you configure the calculated channel, you can see the live value reflecting
whether the signal is Low or High. You can use the formula-based calculated
channel as an input for a trigger event, or like any other channel defined in
the Channel Specification.
Specify a name and description for the calculated channel.
For examples of formula syntax and a
list of supported operators, constants, and functions, refer to the
Calculation Formula Options topic.
Within the formula, enter the name of a hardware channel whose data you
want to manipulate, ensuring that the channel name is enclosed in single
quotes (for example, 'cDAQ1Mod2/ai0' or 'cDAQ1Mod2/port0/line1').
Available channel suggestions appear when you begin typing (‘).
In Formula, specify a formula to apply to data
from an existing channel. Suggested formulas appear when you begin
Calculated channel data is logged with all
other channels configured in your Channel Specification. For more information on
logging data, refer to the Defining Your Test Configuration topic.
