Chapter 4 Working with Signals
© National Instruments Corporation 4-5 Getting Started with LabVIEW SignalExpress
The step selects the two most recent signals from the project to use as
inputs and displays the signals on the graph of the Step Setup dialog
box, as shown in Figure 4-3.
Figure 4-3. Interactive Alignment Step Setup Dialog Box
When you add a step to a project, LabVIEW SignalExpress selects
input signals based on the signal types the step can accept. For
example, the Interactive Alignment step can operate only on
time-domain waveform signals. Therefore, the step selects as inputs
the last two time-domain signals created in the project. To change the
input signals for a step, select different signals from the pull-down
menu of compatible signals in the Input/Output tab of the Step Setup
dialog box.
2. Click the red signal in the Input Signals graph and drag it to another
point within the graph.
You can drag, expand, and contract signals on the graph.
3. Try to align the rising edges of the two signals by dragging a signal
within the graph. Click a signal to set an anchor point and press and
hold the <Alt> key to stretch the signal around that anchor point in the
x and y directions.
