Dialog Box Options

Parameter	Description
Mathematical Operation	Contains the following options: Differential—Returns the differential of the signal. Difference—Returns the difference of the signal. Integral—Returns the integral of the signal. Summation—Returns the value of the sum of all the values of a packet.
Calculation Mode	Contains the following options: Continuous calculation—Uses data from previous segments of data in performing the calculation. Per segment calculation—Does not use data from previous segments of data in performing the calculation.
Result Name	Contains the following options: Use mathematical operation name—Displays the name of the mathematical operation as the name of the Express VI on the block diagram. Express VI name—Displays the name of the Express VI on the block diagram. Remove the checkmark from the Use mathematical operation name checkbox to edit the name of the Express VI.
Input Signal	Displays the input signal. If you have not wired the Express VI and run it to obtain real data, Input Signal displays sample data.
Result Preview	Displays a preview of the measurement.

Block Diagram Inputs

Parameter	Description
Signals	Contains the input signal or signals.
error in (no error)	Describes error conditions that occur before this VI or function runs.

Block Diagram Outputs

Parameter	Description
Result	Returns the resulting data based on the configuration of the Express VI.
error out	Contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.

This Express VI uses the functionality of the following VIs and functions:

Derivative x(t)
Integral x(t)
