6.4.4.1. Reading Probe Data

You can read data by selecting the ALTSOURCE_PROBE instance in the Instance Manager pane and clicking Read Probe Data.

This action produces a single sample of the probe data and updates the data column of the selected index in the In-System Sources and Probes Editor pane. You can save the data to an event log by turning on the Save data to event log option in the Instance Manager pane.

If you want to sample data from your probe instance continuously, in the Instance Manager pane, click the instance you want to read, and then click Continuously read probe data. While reading, the status of the active instance shows Unloading. You can read continuously from multiple instances.

You can access read data with the shortcut menus in the Instance Manager pane.

To adjust the probe read interval, in the Instance Manager pane, turn on the Manual option in the Probe read interval sub-pane, and specify the sample rate in the text field next to the Manual option. The maximum sample rate depends on your computer setup. The actual sample rate is shown in the Current interval box. You can adjust the event log window buffer size in the Maximum Size box.
