The Analog Input dialog window in the Test Panels window. This shows the physical channel associated with the virtual channel, see Figure In general, differential signal coupling is preferrable to single ended coupling due to better DC noise suppression. Figure 7 shows MAX. The price is NOK. To prepare for the loopback test, we wire together AI0 and AO0.

This shows the physical channel associated with the virtual channel, see Figure A local virtual channel exists drover within it's parent task, while a global virtual channel dqa be used in several tasks.
Before you start using the USB, you should attach labels to the analog and digital terminals. Voltage range is 0 - 5V fixed. Window where you select the measurement type. Creating tasks is a general feature of the MAX utility, i.
NI USB-6009
You can use the Index Array function on the Array palette. Above we created a task for an analog input. In the Voltage Output dialog windowselect any voltage between 0V and 5V. When the wizard has finished the installation of the driver software, the USB is ready for use after you click Finish Norwegian: To see the details about a virtual channel, you can click the Show Details buttoncf.

In general, a task can contain one or more global or local virtual channelsand one such virtual channel is based on one physical channel having e. Here, let us test analog output channel 0 AO0 and the analog input channel drivver AI0 to see if they work correctly. Window where you can enter the name of the task. Most of these are described in the following.
Note how the task value the magenta coloured line is propagated through the relevant functions. Drlver has only open-drain output.
Figure 20 shows the contents of the DAQmx palette. These tasks are referred to in the application program, e.
We may then repeat this procedure for other channels. Input high is between 2.

6009 USB features are described separately. The configuration can be saved using the Save button, see Figure These 12 channels are organized in ports, with Port 0 having lines 0.
More free tutorials are available at http: In the folllowing it described how to create tasks for the analog input and the analog output operations.
Here is a video that shows the steps: The latter is available on the CD shipped with the device, and can alternatively be downloaded for free from http: We will perform a very simple test, which is sufficient if we are to check that both AO0 and AI0 work correctly.
Input low is between From the list of measurements type, we select in our case Voltagewhich opens criver window shown in Figure 15 where you can enter the name of no task.
The price is NOK.
caq You can create a task for analog output in the same way, that is, by selecting Create Task in the right-click menu of the USB device as it appears under Devices and Interfacessee Figure 8.
Tasks and virtual channels can be given any name e.
In general, differential signal coupling is preferrable to single ended coupling due to better DC noise suppression.
