You want users to be able to choose the filter bandwidth value, so you can create a control at the AC filter bandwidth terminal. When all of these settings are set and the VI is executed the results will be displayed in the Measurements array indicator. Create a control for the name or relative path terminal on the left-hand side of the Build Path node. The Utility VIs might also include other custom instrument driver VIs that perform operations such as calibration or storage and recall of setups. Then wire together the error out terminal of the Write Delimited Spreadsheet node to the error in terminal of the Close node.

Expand the Build Array node to include multiple elements.

You can change the measurement type by going to the panel and changing the function control to match your measurement. Then the Configure Measurement VI is called to set the instrument up for the desired measurement. However, LabVIEW Plug and Play instrument drivers are distributed with their block diagram source code, so you can customize them for a specific application. Each routine corresponds to a programmatic operation such as configuring, reading from, writing to, and triggering the instrument.

Rename this indicator New File Path. You also can use the Instrument Driver Finder to open example programs covering everything from analysis and presentation to using your instrument driver. In the following figure we have opened the Agilent Read Multiple Measurements.

Connect the purple instrument and yellow error wires between the Configure Measurement node and Configure Autozero node.


Create a control for the name or relative path terminal on the left-hand side of the Build Path node. Action VIs are different from Configuration VIs because they do not change the instrument settings but order the instrument to carry out an action based on its current 34141a. Then create an indicator for the new file terminal on the top right of the Write Delimiter Spreadsheet node.

You can configure the Histogram node with several inputs. Each VI corresponds to a programmatic operation, such as configuring, reading from, writing to, and triggering an instrument.

The NI Instrument Driver Network houses thousands of instrument drivers for automating third- party instruments. Add a control to the Configure AC Filter function so users can choose a filter bandwidth immediately from the panel.

Connect 34411x appended array terminal on the Build Array node to the 2D data terminal on the Write Delimited Spreadsheet node. Feel free to move objects around to add space for these new nodes.

Wire together the system directory terminal on the top right of the Get System Directory node to the base path terminal on the top left of the Build Path node. After you call these VIs, labvoew instrument is ready to take measurements or to stimulate a system. To create a constant input for the Configure AC Filter node so that the filter bandwidth is always the same, create a constant at the AC filter bandwidth terminal on the Configure AC Filter node.

Rename the X and Y axis of the Histogram 34141a to correspond with the values being measured by clicking on axis label and replacing the text or by clicking on the axis label and changing the Name text at the top of the Configuration pane on the right.


Drop down all the indicators and controls from the Unplaced Items box onto the panel.

Reposition controls on the diagram as needed to make room for extra controls. The default value is Create a Manual Range control for the Configure Measurement function by right-clicking the manual range 1 terminal and selecting Create control.

Create space between the Read Multiple Points node and the Close node. Learn more about our privacy 34411w.

Open the Learning tab by selecting the Learn to Program tile in the Welcome screen or select the Learning tab from the top right. First ensure you have the NI-Serial driver installed. Rate this document Select a Rating 1 – Poor 2 3 4 5 – Excellent.

Place the new control on the panel by selecting the Unplaced Items box and placing it onto the panel. In this example, serial communication is used. The following figure shows this palette and some of the VIs and subpalettes that are shipped with it. An instrument driver is a set of software routines that control a programmable 3441a. Enabling autozero optimizes the instrument for accuracy, while disabling optimizes for speed.
