| Parameter | Description |
|---|
| Mathematical Operation | Contains the following options:
- Derivative (dX/dt)—Returns the numeric derivative of the signal. LabVIEW computes the output sample of dX/dt at index i as yi=(xi– xi–1)/dt.
- Difference (dX)—Returns the numeric difference of the signal. LabVIEW computes the output sample of dX at index i as yi=xi–xi–1.
- Integral (Sum[Xdt])—Returns the numeric integral of the signal. LabVIEW computes the output sample of Sum[Xdt] at index i as yi=yi–1 + xidt.
- Summation (Sum[X])—Returns the summation of the signal. LabVIEW computes the output sample of Sum[X] at index i as yi=yi–1 + xi.
|
| 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 wire data to the Express VI and run it, Input Signal displays real data. If you close and reopen the Express VI, Input Signal displays sample data until you run the Express VI again. |
| Result Preview | Displays a preview of the measurement. The Result Preview plot indicates the value of the selected measurement with a dotted line. If you wire data to the Express VI and run it, Result Preview displays real data. If you close and reopen the Express VI, Result Preview displays sample data until you run the VI again. If the cutoff frequency values are invalid, Result Preview does not display valid data. |
