Configuring FlexLogger for Step Voltage Output

This article provides step-by-step instructions for configuring NI FlexLogger to output a step voltage using the NI-9263 analog output module and verify the signal using the NI-9239 analog input module. It also includes guidance on integrating the FlexLogger Test Sequencer Plug-in from GitHub to output a step voltage.

1. Launch NI FlexLogger and Create Project

   1. Launch NI FlexLogger.
   2. Click New Project and assign a name.
   3. Select the appropriate hardware
      1. NI-9263 as analog output module.
      2. NI-9239 as analog input module.
   4. Connect the NI-9263 AO0 to the NI-9239 AI0
   

2. Add and Configure Analog Input

   1. Navigate to the Channel Specification tab.
   2. Locate NI-9239 AI0 and click Configure.
   3. Rename the channel if needed for clarity.
   4. Set the Physical Measurement to Voltage.

3. Use FlexLogger Plug-in to Output Step Voltage

   1. Download the FlexLogger Sequencer Plug-in from GitHub. The link can be found below.
      1. niflexlogger-plugins/plugins/Sequencer with Output Values at main · ni/niflexlogger-plugins · GitHub
   2. Follow the Getting Started instructions in the GitHub repository to add the plug-in to the FlexLogger.
   3. In FlexLogger, go to Add Channels > Plug-In > Sequencer With Output Values.
   4. Select Sequencer With Output Values and click Configure.
   5. Set the configuration to output step voltages from 0V to 3V, with each step lasting 0.1 second.
   6. Click Apply.

4. Add and Configure Analog Output

   1. Go to Channel Specification tab.
   2. Locate NI-9263 AO0 and click Configure.
   3. Rename the channel if deem necessary.
   4. Set the Physical Generation to Voltage.
   5. Set the Output Source to use Analog Channel 0 from the Sequencer with Output Values plug-in.

5. Verify the Result

   1. Go to the Screen tab in FlexLogger.
   2. Drag the High-Speed Graph onto the screen.
   3. Select the Analog Input channel (NI-9230 AI0).
   4. Press Run and verify output signal from Analog Output to Analog Input.
