ID Known Issue
506610

NI-VNA measurements are incorrect after loading multiple CHX files using the niVNA Load Calibration And Configuration Data From File VI or the niVNA_LoadCalibrationAndConfigurationDataFromFile function.
After loading multiple CHX files using the niVNA Load Calibration and Configuration Data From File VI or the niVNA_LoadCalibrationAndConfigurationDataFromFile function, the returned measurement data is incorrect. Reversing the order that you load the CHX files in gives the correct data.

Workaround: To avoid incorrect measurement data when you load multiple CHX files, complete one of the following tasks:

  • Reset the device using either the niVNA Reset VI or the niVNA_reset function before loading the CHX files
  • Load the CHX file twice before taking a measurement.

496962 NI-VNA occasionally fails to export End of Step and End of Sweep events to the PXI_TRIG lines.
NI-VNA occasionally fails to export End of Step and End of Sweep events to the PXI_TRIG lines despite these events being configured to export. This is a rare occurrence, but when it does happen, all exported edges fail to be sent.

Workaround: Repeat the sweep. If the End of Step or End of Sweep events are configured to export, they will likely be correctly exported the next sweep.

Reported Version: 14.0    Resolved Version: N/A    Added: 10/07/2014

200090 The NI-VNA Soft Front Panel cannot load when using Remote Desktop on Windows XP.
The NI-VNA Soft Front Panel does not load in a remote desktop environment on Windows XP. The splash screen shows "Application Initialization Failed!" This error only occurs when the NI-VNA Soft Front Panel is running on Windows XP. Remote Desktop works successfully on Windows Vista and Windows 7. You can use any supported OS on the client; you will only see this problem if you use Windows XP as the server (the system with the hardware) operating system.

Workaround: Install Windows Vista or Windows 7 on the NI-VNA system.

Reported Version: 1.0    Resolved Version: N/A    Added: 10/25/2010
494957 NI-VNA cannot export the Ready for Start event.
NI-VNA cannot export the Ready for Start event. If you try to export the Ready for Start event, NI-VNA will return an error.

Workaround: There is no workaround for this issue.

Reported Version: 14.0    Resolved Version: N/A    Added: 10/07/2014
460163 NI-VNA Soft Front Panel does not reserve PXI_TRIG lines.
The NI-VNA Soft Front Panel does not programmatically reserve PXI_TRIG lines. You can export events to PXI_TRIG lines for synchronization; however, it is possible to double-drive a PXI_TRIG line if care is not taken.

Workaround: Manually reserve and unreserve the PXI_TRIG lines using NI MAX.

Reported Version: 2.0.3    Resolved Version: N/A    Added: 9/23/2014
453927 The NI PXIe-5632 sends a spurious pulse on any active PXI_TRIG line when you configure it for a Rising Edge or Active High Level output event in the NI-VNA Soft Front Panel.
When you configure the PXIe-5632 to use a Rising Edge or Active High Level output event for single sweep and hold measurements using the NI-VNA Soft Front Panel (SFP), the device sends a single spurious pulse on the configured PXI_TRIG line at the beginning of each sweep.

Workaround: To avoid all spurious pulses on the PXI_TRIG lines, configure any output events to be Falling Edge or Active Low Level.

Reported Version: 2.0.3    Resolved Version: N/A    Added: 9/15/2014
492581 NI-VNA does not support IVI interchangeability checking or coercion recording.
NI-VNA does not implement interchangeability checking or coercion recording. These features are optional features of IVI drivers. If you set the NIVNA_ATTR_INTERCHANGE_CHECK attribute or the NIVNA_ATTR_RECORD_COERCIONS attribute to VI_TRUE, NI-VNA should return an error, but does not.

Workaround: There is no workaround for this issue.

Reported Version: 14.0    Resolved Version: N/A    Added: 9/15/2014
250239 Users can receive a misleading error message when loading an AutoCal characterization file.
The NI-VNA instrument driver and Soft Front Panel return a misleading error message if you attempt to load the AutoCal characterization file either without having the AutoCal module connected or if the file is read-only on your system. If you call the niVNA Load AutoCal Characterization Data From File VI or function with no AutoCal module connected or if the file has been set to read-only, the VI or function fails with a "File not found" error. In the Soft Front Panel, the error returned is "Failed to read. You might have a corrupted file." The error should instead indicate that no AutoCal box was found, or the file is read-only.

Workaround: Connect AutoCal box before calling this VI or function. Change the AutoCal characterization file to not be read-only.

451229 The NI PXIe-5632 continues to drive PXI_TRIG lines after you close the NI-VNA Soft Front Panel.
The NI PXIe-5632 fails to release PXI_TRIG lines after you close the NI-VNA Soft Front Panel (SFP). If you configured PXI_TRIG lines in the NI-VNA SFP, they will remain driven in the state in which they were last used. As a result, if another device attempts to use the PXI_TRIG lines afterward, the lines may be double driven and damage may occur.

Workaround: To avoid double driving the PXI_TRIG lines after using them in the NI-VNA SFP, complete one of the following tasks:
  • If you are using output events, set the output events to Do Not Export and perform at least one sweep before closing the NI-VNA SFP.
  • If you are using triggers, set the trigger source to Internal and perform at least one sweep before closing the NI-VNA SFP.

Reported Version: 2.0.3    Resolved Version: N/A    Added: 9/15/2014
245461 The NI-VNA Soft Front Panel consumes all the video memory.
The NI-VNA Soft Front Panel can use up the available video memory, resulting in it either loading with all traces blank or closing with an error. This situation typically happens with multiple VNAs in the system and happens intermittently.

Workaround: Close NI-VNA Soft Front Panel and reopen it.

Reported Version: 1.0    Resolved Version: N/A    Added: 10/25/2010
451230 The NI PXIe-5632 sends spurious pulses on previously used PXI_TRIG lines when the NI-VNA Soft Front Panel is closed.
The NI PXIe-5632 fails to release PXI_TRIG lines after you close the NI-VNA Soft Front Panel (SFP). If you configured PXI_TRIG lines in the NI-VNA SFP, there may be some spurious signals on these lines when you close the NI-VNA SFP.

Workaround: To avoid spurious signals on the PXI_TRIG lines after using them in the NI-VNA SFP, complete one of the following tasks:
  • If you are using output events, set the output events to Do Not Export and perform at least one sweep before closing the NI-VNA SFP.
  • If you are using triggers, set the trigger source to Internal and perform at least one sweep before closing the NI-VNA SFP.

Reported Version: 2.0.3    Resolved Version: N/A    Added: 9/15/2014

Workaround: Use NI-VNA examples through the LabVIEW application programming interface.

Reported Version: 1.0    Resolved Version: N/A    Added: 5/20/2013
246949 NI-VNA returns "Device in Use" error when device is unavailable.
If you use NI-VNA to open a session to a device that has recently been powered off or disconnected, the Initialize VI or function returns a "Device in Use" error instead of a "Invalid Device" error.

Workaround: Open a session to a valid device.

Reported Version: 1.0    Resolved Version: N/A    Added: 10/25/2010
456886 NI-VNA does not calibrate with the AutoCal over a remote desktop connection when you share serial ports over the remote desktop connection.
Executing the AutoCal calibration over a remote desktop connection results in an error caused by sharing serial ports over the remote desktop connection.
