Installing a Previous Version of InstrumentStudio Causes All Project Files to Open With the Most Recently Installed Version

Project files will open with the most recently installed version of InstrumentStudio. For example, if you install InstrumentStudio 2020, create and save projects in that version, and then install InstrumentStudio 2019, the project files created in InstrumentStudio 2020 will open by default with InstrumentStudio 2019. InstrumentStudio projects and documents are not backward-compatible, so the project will give an error saying that it failed to load.

Workaround:

Change the Windows file association for .instudioproj files to the latest version or repair the InstrumentStudio installation with the desired default project version.

Digital Trigger Sources Do Not Update After Renaming a Device in MAX

If you rename an Oscilloscope device in MAX, the new name will not automatically appear in the list of digital trigger sources in the InstrumentStudio Oscilloscope panel. After renaming one or more devices, errors occur when attempting to use those digital trigger sources.

Workaround:

Select a different trigger type in the InstrumentStudio Oscilloscope panel and then select Digital triggering again. This will force the list of trigger sources to refresh.

Capture Screenshot Does Not Capture Whole Panel When DPI Scaling Is Greater Than 100%

If your PC display settings are configured to use a DPI scaling greater than 100%, the capture screenshot and capture data (when configured to include a screenshot) functions in InstrumentStudio will not capture an image of the whole panel. 

Workaround:

In the Windows Display settings, change the scaling to 100% before using InstrumentStudio's Capture Screenshot function or including the screenshot with the Capture Data function. You can also use built-in Windows or third-party tools to capture a screenshot instead.

Pins Using Multiplexed Connections Are Not Shown Under the Correct Site in InstrumentStudio

InstrumentStudio does not currently support multiplexed connections in pin maps. If the site filter is set to a specific site, pins under that site will not appear in the panel if they are mapped in the pin map using multiplexed connections.
The channels using multiplexed connections will appear under Unmapped channels if the Site filter is set to All sites, but will not display the pin names from the pin map.

Workaround:

There is currently no known workaround for this issue.

SMU Waveform Mode May Not Graph Data for All Selected Channels With High Capture Times

When multiple channels are enabled in SMU Waveform mode and selected for display on the graph, InstrumentStudio may fail to acquire waveform data for all of the selected channels when you increase the capture time, depending on the channel count and capture time used.

Workaround:

Reduce the capture time or limit the number of channels you are acquiring data from

Oscilloscopes Fails to Auto-Monitor When the Devices in the Panel Are Different From the Devices in the External Session

If you are using an Oscilloscope panel with multiple oscilloscopes, and then run test code which has separate sessions for one or more of the same devices, then InstrumentStudio will get stuck in a running/stopped loop and will be unable to monitor or acquire data from any of the devices.

Similarly, if you are using a single oscilloscope in a standalone panel in InstrumentStudio and then run test code that uses channel expansion to open a single session to more than one device, including the one used in InstrumentStudio, then the panel will be unable to monitor the session and will enter an unusable state.

Workaround:

To monitor the external session, use Manual layout to create a panel containing the same devices that are used in the external session.

SMU/Power "Export To TestStand" Measure When property in exported IO Configuration is different before and after running the panel

The IO Configuration generated when clicking on "Export to TestStand" in an SMU/Power Supply panel will be different before and after running the panel. Specifically, the "Measure When" (NIDCPOWER_ATTR_MEASURE_WHEN) property will have different values:
  • Value before running: 1025(Automatically after Source Complete)
  • Value after running: 1027(On Measure Trigger)
 
This will affect results if used in read measurement steps within TestStand.

Workaround:

There is currently no known workaround for this issue.
