IDKnown Issue
276615

Return
Cannot enable a Peer-to-Peer stream after calling an Abort.
When you abort a Peer-to-Peer stream using niP2P Abort, you cannot call the niP2P Enable function until you call the niP2P Flush and Disable function first.

Workaround: Call "niP2P Flush and Disable Peer to Peer Stream" first. Then call "niP2P Enable Peer to Peer Stream"

278469

Return
Hibernating a system with a PXIe 5185/5186 immediately after booting will cause the system to hang
When the system boots, the NI 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.

Reported Version: 3.8  Resolved Version: N/A  Added: 02/14/2011
280321

Return
Measurement & Automation Explorer (MAX) appears to hang when resetting an NI PXIe 5185/5186
If an NI 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
NI 5622 acquisitions synchronized using TClk can be misaligned under certain conditions
When using TClk synchronization where two or more NI 5622 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.

Reported Version: 3.6  Resolved Version: N/A  Added: 03/16/2011
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.

Return
NI 515x Devices and NI-TClk Synchronization
When using an NI 5152/ 5153/ 5154 device in TIS mode with NI-TClk synchronization and an external sample clock, the devices configured as the TClk slaves may fail to respond to reference triggers.

Workaround: No current workaround.

Reported Version: 3.6  Resolved Version: N/A  Added: 03/16/2011
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.

Reported Version: 3  Resolved Version: N/A  Added: 03/16/2011
287154

Return
5112 Trigger Holdoff Period Must Expire Before You Initiate another Acquisition
Using NI-SCOPE, you can now read data as soon as it is acquired. However, on a single record acquisition, the fetch functions do not wait for the trigger holdoff to expire. If you configure a trigger holdoff on a single record acquisition on NI 5112 devices, you must make sure the trigger holdoff period has expired before initiating another acquisition.

Workaround: Call niScope_AcquisitionStatus to find out when the entire acquisition, including trigger holdoff, has completed.

Reported Version: 3  Resolved Version: N/A  Added: 03/16/2011
287156

Return
NI 5122 - Changing the Rate of the External Clock
When using an NI 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.

Reported Version: 3.5.1  Resolved Version: N/A  Added: 03/16/2011
287160

Return
NI PXI/PCI-5142, NI 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. For all cases, it is assumed that the DDC is enabled. If the DDC is not enabled, there are no restrictions on TClk synchronization.

Workaround: Add red/green table for more information on which configurations are supported.

Reported Version: 3.6.1  Resolved Version: N/A  Added: 03/16/2011

Return
Error -250043 occurs at niTClk Synchronize when synchronizing different device models
An error can occur if the TClk timebase of the Sync Pulse Sender device is not a multiple of the timebase of each slave device.

Workaround: If you have set the Absolute Sample Clock Offset or Phase DAC Oscillator NI-SCOPE properties on synchronized devices of different model numbers, place a different device model first in the array of session references that are being synchronized.
