| 278469 Return | Hibernating a system with a PXIe-5185/5186 immediately after booting will cause the system to hang When the system boots, the PXIe-5185/5186 performs a power-up calibration procedure. If the system is forced to hibernate/sleep while the power-up calibration is in progress, you will have to wait until the calibration is complete before the system can be brought out of hibernation. The LEDs on the PXIe-5185/5196 turn green once power-up calibration is complete. Workaround: Wait until the power-up calibration is complete.
| |||||
| 280321 Return | Measurement & Automation Explorer (MAX) appears to hang when resetting a PXIe-5185/5186 If a PXIe-5185/5186 is in the process of calibrating to a clock source and MAX requests a device reset, MAX must wait until the clock source calibration is complete and will be unresponsive. Clock source calibration can take several minutes. Workaround: Wait until clock source calibration completes.
| |||||
| 258807 Return | PXIe-5622 acquisitions synchronized using NI-TClk can be misaligned under certain conditions When using TClk synchronization where two or more PXIe-5622 modules acquire at different I/Q rates with DDC enabled, it is possible for the acquired data to be misaligned. The misalignment manifests itself as a skew where the data from one device appears to be leading/lagging the data from the other device. The time delay between the data acquired by the master and a slave is constant for the combination of the hardware settings configured on the two devices. This skew is repeatable and does not vary with time. Workaround: Since the skew does not vary with time, users can empirically determine the expected misalignment and correct the acquired data manually.
| |||||
| 285864 Return | Dynamic Mode in the LabVIEW FPGA Module is not Supported with P2P Streaming Using dynamic FPGA interfaces (also known as dynamic mode) in the LabVIEW FPGA Module is not supported when using peer-to-peer streaming. Workaround: Dynamic mode is enabled by default in the LabVIEW FPGA Module 2010. To disable Dynamic mode, complete the following steps: 1. Place the Open FPGA VI Reference function on the LabVIEW block diagram. 2. Right-click the function and select Configure Open FPGA VI Reference. 3. Remove the checkmark from the Dynamic mode listbox.
| |||||
| 287099 Return | Traditional NI-DAQ installs support for only the latest installed version of LabVIEW Beginning with version 7.4.2, Traditional NI-DAQ (Legacy) will install support for the latest version of LabVIEW found on the system. Workaround: If you require support for more than one version of LabVIEW, complete the following steps: Install Traditional NI-DAQ (Legacy)(included in the NI-SCOPE installer). Restart the system. Copy the following folders from the latest version of LabVIEW to the folder of the older version of LabVIEW. [LVDIR] indicates the folder of the latest LabVIEW version. [LVDIR]\vi.lib\daq [LVDIR]\examples\daq [LVDIR]\help\lvdaq.chm [LVDIR]\menus\default\daq You should now be able to use Traditional NI-DAQ (Legacy) with both versions of LabVIEW. The Traditional NI-DAQ (Legacy) API is mass-compiled in LabVIEW 7.0. This will not affect the functionality of your VIs. However, LabVIEW will prompt you to save the Traditional NI‑DAQ (Legacy) subVIs if your LabVIEW version is greater than 7.0. To avoid the prompts, mass-compile the folders referenced above. If you require Traditional NI‑DAQ (Legacy) support for earlier versions of LabVIEW, you need an earlier version of Traditional NI-DAQ (Legacy).

| 287104 Return | NI-SCOPE P2P Example Projects Prompt for Save on Close NI-SCOPE P2P Example Projects Prompt for Save on Close Workaround: NI-SCOPE Peer-to-Peer examples may require you to save them after opening the examples for the first time.
| |||||
| 287106 Return | Window/FFT Results Differ between NI-SCOPE and LabVIEW If you perform a Window/FFT in NI-SCOPE, the results are slightly different compared to similar functions in LabVIEW. This is because NI-SCOPE uses a slightly different definition of Windowing than LabVIEW uses. Workaround: Refer to the NI High-Speed Digitizers Help for information on windowing.
| |||||
| 287112 Return | PXI/PCI-515x Devices and TClk Synchronization When using a PXI/PCI-5152/5153/5154 in TIS mode with NI-TClk synchronization and an external sample clock, the modules configured as the TClk slaves may fail to respond to reference triggers. Workaround: No current workaround.
| |||||
| 287114 Return | Downgrading NI-SCOPE If you need to downgrade the current version of NI-SCOPE to NI-SCOPE 2.1.4 or earlier, you must uninstall the current versions of NI-SCOPE and NI-DAQmx before installing the older version of NI‑SCOPE. After the older version of NI-SCOPE is installed, you can then reinstall NI-DAQmx. Workaround: Uninstall the current installed versions of NI-SCOPE and NI-DAQmx before installing the older version of NI-SCOPE. After the older version of NI-SCOPE is installed, you can then reinstall NI-DAQmx.
| |||||
| 287156 Return | PXIe/PXI/PCI-5122 - Changing the Rate of the External Clock When using a PXIe/PXI/PCI-5122, to change the rate of the external clock within the same session, you need to first change the rate by setting the Sample Clock Timebase Rate attribute, then change the rate of your source, then call the function niScope_Commit. If you change the rate of the source before setting the attribute, you may get an error. Workaround: Another workaround is to abort the acquisition after fetching the data but before changing the rate.
| |||||
| 287160 Return | PXI/PCI-5142, PXIe-5622 TClk Synchronization is not Fully Supported for Certain Cases When the DDC Enabled property or the NISCOPE_ATTR_DDC_ENABLED attribute is set to True, there are certain configurations for which shared triggers cannot be TClk synchronized.
