Expand the Build Array Node to add an extra terminal by dragging down with the mouse after seeing the expansion cursor appear on the bottom of the Node. It sources voltage or current while making measurements without needing to change connections. The multimeter capabilities include high repeatability and low noise. Do the same for actual maximum and actual minimum terminals on the right hand side of the Histogram Node. On the Build Array Node connect the first terminal Element 1 to the voltage indicator wire, Element 2 to the current indicator wire, and Element 3 to the resistance indicator wire.

You can also troubleshoot and make manual function calls to your instrument to ensure keitjley it is working as expected before moving into automation. The tightly coupled nature of a SourceMeter SMU instrument provides many advantages over solutions configured from separate instruments, such as a precision power supply and a digital multimeter.
Moves from the start level to the stop level in equal linear steps. When writing an instrument control application for a serial instrument, you will communicate with a COM port rather than the serial instrument connected to the COM port. All SourceMeter SMU instruments include Keithley’s unique Trigger Link interface which provides high-speed, seamless communications with many of Keithley’s other instruments.
It also protects the device under test from damage due to accidental overloads, thermal runaway, etc. Create some extra space here by holding Ctrl while clicking and dragging your mouse to the right on the Diagram. Rate this document Select a Rating 1 – Poor 2 3 4 5 – Excellent. NI develops and supports thousands of 24440 Drivers for 3 rd party instruments to help engineers and scientists automate measurements.
Keithley SourceMeter – Instrument Driver – National Instruments
Select the center of the graph and change the plot type by selecting Bar in the Plots section of the Configuration Pane. The multimeter capabilities include high repeatability and low noise.
The combination of power and precision allows you to use the same instrument for both high power sweeps and low current measurements; while the addition of a high-speed update rate and sampling rate allow you to use the instrument in non-traditional ways, such as generating and measuring a waveform.
We want users to be able to choose to have the Auto Zero enabled, disabled, or run immediately so we will create a Control at the Autozero terminal. The COM port will not show up in the Hardware tab.
The “File Name” control enables users to name the new. Open the Learning tab by selecting Learn to Program tile in the Welcome screen or select the Learning tab from the top right.
Click the Keithley 24XX oeithley to create a new copy. Other capabilities of the interface include: To create a constant input for the Auto Zero node so that the Auto Zero is always enabled, create a Constant at the Autozero terminal on the Auto Zero node. Test management software e. To provide the throughput demanded by production applications, the SourceMeter SMU instrument offers many built-in features that allow it to run 4240 test sequences without computer control or GPIB communications slowing things down.
Open these examples using the following procedure. Delete the purple Instrument and yellow Error wire connecting the Configure Measurement node and Configure Output node by selecting both wires and pressing the Delete key. Add an input for the number of bins to create by right clicking the number of bins 10 terminal on the left hand side of the Histogram Node and selecting Create control. Both the current and voltage source are programmable with readback to help maximize device measurement integrity.
Wire together the Voltage values so that they feed into the Signal terminal of the Histogram Node. Sequencing and Database Reporting with TestStand Test Management Software TestStand is a keithlsy test management software that is designed to help you develop, execute, and deploy automated test and validation systems faster. Connect the purple Instrument and Yellow error wires between the Configure Measurement node and Configure Output node.
Go back to the Panel by selecting Panel on the View Selector. In the second and fourth quadrants they operate as a sync, dissipating power internally.
The procedure for detecting your device depends on the bus being used. The default value is You can then place items down one by one on the Panel. 244
Providing the finest test equipment solutions since 1992
If the readback reaches a programmed compliance limit, then the source is clamped at the limit, providing fault protection. Create a Manual Range control for each Configure Measurement by right clicking each “manual range 1 ” terminal and selecting Create control.
For example, it provides faster test times by reducing GPIB traffic and simplifies the remote programming interface. Back to Top 7.
