Logging Data
You can use LabVIEW SignalExpress to record and analyze
measurements. You can record any time-domain, double, U32, or Boolean
step output. You also can analyze and process logged data by playing it
through analysis steps.
This chapter teaches you how to record data using the integrated data
logging features in LabVIEW SignalExpress. You learn how to record a
specified signal, play back that signal, and analyze the signal using analysis
steps. You also learn how to use the Recording Options View to log signals
based on specified start or stop conditions.

Recording a Signal

You can use the Record button to configure a data logging process.
Complete the following steps to specify a signal to record and to record the
signal.
1. Select File»Open Project, navigate to the SignalExpress\
Examples\Tutorial directory, and double-click
Logging.seproj.
This project uses the Create Signal step to generate a signal based on a
formula.
2. Click the Record button, shown at left, to open the Logging Signals
Selection dialog box.
The Logging Signals Selection dialog box displays the signals in the
project available for recording. You can select one signal or multiple
signals to record. You also can specify a name and description for
the log.
3. Place a checkmark in the signal checkbox to record the fo rmula signal
generated in the Create Signal step.
4. Click the OK button to close the Logging Signals Selection dialog
box and begin recording the signal. The logging operation continues
until you click the Stop button.
