Installing/Uninstalling/Modifying NI-SCOPEInstalling NI-SCOPE

This section provides information on installing NI-SCOPE and NI-DAQ and upgrading from previous versions of NI-SCOPE.

NI-SCOPE installs NI-DAQ if it is not already installed, or if an earlier version of NI-DAQ is installed. NI-DAQ support files will be installed if you have LabVIEW or LabWindows/CVI in your system. However, the only component that NI-SCOPE needs from NI-DAQ is the device driver.

Upgrading from a Previous Version of NI-SCOPE

Upgrading from NI-SCOPE 1.0 and 1.1—NI-SCOPE 3.5 does not install over NI-SCOPE 1.0 or 1.1. You must uninstall these versions of NI-SCOPE before installing NI-SCOPE 3.5.

Upgrading from NI-SCOPE 1.5 and later—NI-SCOPE 3.5 automatically uninstalls any previous version that is greater or equal to 1.5. If you have modified any old examples, these will be overwritten by the new versions.

Uninstalling/Modifying NI-SCOPE

For Windows XP/2000, complete the following steps:

• Launch the Control Panel by selecting Start»Control Panel.
• Double-click Add or Remove Programs.
• Select National Instruments Software.
• Click Change/Remove.
• Select NI-SCOPE 3.5 from the dialog box that appears.
• Click Remove to uninstall the product; click Modify to change the components that are installed.
  

For Windows Vista, complete the following steps:

• Launch the Control Panel by selecting Start»Control Panel.
• Double-click Programs and Features.
• Select National Instruments Software.
• Click the Uninstall/Change button.
• Select NI-SCOPE 3.5 from the dialog box that appears.
• Click Remove to uninstall the product; click Modify to change the components that are installed.
  

Do not attempt to uninstall by deleting files, which may be shared with other programs. The following additional software packages may have been installed as part of the NI-SCOPE installation. Exercise care when removing these packages because they may be used by other NI products:

• IVI Compliance Package
• NI-VISA
• NI-DAQ and NI-DAQmx
• Measurement & Automation Explorer
• NI Hierarchical Waveform Storage

Programming in NI-SCOPE

NI-SCOPE provides an intuitive, full-featured interface for programming your hardware. NI-SCOPE is IVI-Scope compliant. For more information, refer to \Drivers\niScope\Documentation\niScopeIVIComplianceDocument.txt.

Software Examples

NI-SCOPE ships with several examples for LabVIEW, LabWindows/CVI, Measurement Studio, MSVC, Visual C++, and Microsoft Visual Basic that will help you develop your software. These examples illustrate how to perform the most common operations with your hardware. To find the examples, go to Start» Programs»National Instruments»NI-SCOPE»Examples.

NI-SCOPE Soft Front Panel

The NI-SCOPE Soft Front Panel (SFP) is a software oscilloscope application for NI high-speed digitizers. It has the following features:

• Familiar interactive user interface
• Robust architecture
• Scalar measurements
• Save/load waveforms
• Save/load configurations
• Low CPU usage
  

The NI-SCOPE SFP demonstrates some of the capabilities of NI high-speed digitizers and enables you to start using your new digitizer immediately without the need to know a programming language. The NI-SCOPE SFP is installed by default as a feature of the NI-SCOPE installation. To remove the NI-SCOPE SFP use the Add/Remove Programs option.

Bug Fixes

The following items are changes from earlier versions of NI-SCOPE to NI-SCOPE 3.5. If you have a Bug ID, you can search this list to validate that the issue has been fixed. This is not an exhaustive list of issues fixed in the current version of NI-SCOPE.

NI PXIe-5122

A firmware update for the NI PXIe-5122 is available with NI-SCOPE 3.5. Under some circumstances, "Error -50500: A synchronization object was not acquired within the time limit. The operation could not be completed as specified." may occur while fetching data from the digitizer using the previous firmware. This is resolved by updating the NI PXIe-5122 firmware by running NI PXIe-5122 Firmware Updater.exe, the updater utility which installs with NI-SCOPE 3.5 into the following location:

• Windows 2000/XP/Vista 32-bit: Program Files\National Instruments\NI-DAQ\fpgafiles\ni5122\
• Windows Vista 64-bit: Program Files (x86)\National Instruments\NI-DAQ\fpgafiles\ni5122\

Known IssuesUSB Device Stops Responding

If you observe that a USB device stops responding when you insert or remove another USB device in the system, see Knowledge Base 4D4BO9AY at ni.com/support.

Function Reference Help

If you click a topic link in the NI-SCOPE Function Reference Help section of the NI High-Speed Digitizers Help, you cannot use the Back button in the HTML Help window toolbar to return to the original topic.

LabWindows/CVI

The hyperlinks in the function panel context help in LabWindows/CVI versions 7.1 and 7.1.1 do not work unless you have downloaded the most recent version of the launchhelp.js file. Instructions for downloading and installing the file can be found in the KnowledgeBase (KB) entry Why Do I Get "Object Expected" Error When Opening Links in Function Panel Help? You can access this KB by visiting ni.com/info and entering rdnkbe in the Info Code field.

Windows Power Management

NI recommends that you disable Windows power management modes, such as sleep, standby, and hibernate, when using NI-SCOPE. These modes terminate any NI-SCOPE operation in progress. In Windows Vista or on a laptop computer, the default power management settings are likely to enable sleep mode.

Security Prompts

When you run setup.exe to install the software from the CD, you are prompted to choose whether you want to always trust software from National Instruments. If you do not select this option, your installation may be interrupted by one or more Microsoft Windows security dialog boxes. However, if you run setup from the command line, you will not receive this prompt, and the installer will automatically install NI's Software Publisher Certificate to your Windows Trusted Publisher Store. If you do not want to make this change to your Windows Trusted Publisher Store, do not choose this installation method.

LabVIEW Support for Traditional NI-DAQ 7.4.2

Starting with version 7.4.2, Traditional NI-DAQ (Legacy) will install support for the latest version of LabVIEW found on the system. If you require support for more than one version of LabVIEW, complete the following steps:

• Install Traditional NI-DAQ (Legacy) 7.4.2 (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).

NI-SCOPE Soft Front Panel Keyboard Shortcuts

Beginning with NI-SCOPE 3.1, the following shortcuts have changed in the NI-SCOPE Soft Front Panel:

• Increment trigger coupling has changed from to .
• Decrement trigger coupling has changed from to .
• now toggles the cursors.
  

NI-SCOPE Express Step in NI Signal Express 1.0

The NI-SCOPE Express step that ships with NI-SCOPE was designed for use with NI SignalExpress 1.1 or later. The NI-SCOPE Express step is compatible with NI SignalExpress 1.0 with the exception that software start triggers are not supported.

TClk Connector Alignment in NI-SCOPE 2.7 and Later

If you are using NI-TClk to synchronize non-identical devices (for example, an NI PXI-5122 with an NI PXI-5124), you will notice a change in behavior in the skew associated with synchronization when you upgrade from NI-SCOPE 2.6.1 to a later version. The new behavior compensates for delay associated with the input path. This delay varies from device to device. Because the driver now handles this delay, synchronizing any SMC-based products should produce data that has a small constant skew over all sample rates.

NI 5102

Board revision 183612F-01 of the NI PCI-5102 and board revision 184603E-01 of the NI PXI-5102 must be used with NI-SCOPE 2.6.1 or later. Board revision 183442G-01 of the NI PCMCIA-5102 must be used with NI-SCOPE 2.8 or later. To verify the board revision number, remove the device from the computer or chassis and turn it to view the side. The revision number is labeled "ASSY" and is located near the serial number. If you have an earlier version NI-SCOPE installed, go to ni.com/idnet to download the latest version.

NI 5112

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, you must make sure the trigger holdoff period has expired before initiating another acquisition. Call niScope_AcquisitionStatus to find out when the entire acquisition, including trigger holdoff, has completed.

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. Another option is to abort the acquisition after fetching the data but before changing the rate.
• Board revision 190100B-01 of the NI PXI-5122 must be used with NI-SCOPE 2.7 or later. To verify the board revision number, remove the device from the computer or chassis and turn it to view the side. The revision number is labeled "ASSY" and is located near the serial number. If you have an earlier version of NI-SCOPE installed, go to ni.com/idnet to download the latest version.
  

NI PXI/PCI-5142, NI PXIe-5622

TClk synchronization is not fully supported for certain cases. When the DDC Enabled attribute is set to True, there are certain configurations for which shared triggers cannot be TClk synchronized. The following table explains which triggers can be TClk synchronized for different configurations. For all cases, it is assumed that the DDC is enabled. If the DDC is not enabled, there are no restrictions on TClk synchronization.

Configuration	5142				5622
	Start Trigger	Reference Trigger (Digital)	Reference Trigger (Analog Edge)	Reference Trigger (Power Edge)	Start Trigger	Reference Trigger (Digital)	Reference Trigger (Analog Edge)	Reference Trigger (Power Edge)
Fractional Resampling Off, All Cases	Y	Y	Y	N	Y	Y	N/A	N
Fractional Resampling On, Single-Record, Homogeneous Sample Rates	N/A	N/A	N/A	N/A	Y	Y	N/A	N
Fractional Resampling On, Single-Record, Heterogeneous Sample Rates	N/A	N/A	N/A	N/A	Y	N	N/A	N
Fractional Resampling On, Multi-Record, Homogeneous Sample Rates	N/A	N/A	N/A	N/A	Y	Y	N/A	N
Fractional Resampling On, Multi-Record, Heterogeneous Sample Rates	N/A	N/A	N/A	N/A	Y	N	N/A	N

Note: Reference triggers that cannot be TClk synchronized (such as power edge reference triggers) can still be shared between devices by exporting them using the niScope Export Signal VI or the niScope_ExportSignal function.

NI 5911

When you synchronize multiple NI 5911 digitizers in master-slave mode, the sample rate must be 100 MHz, 50 MHz, or 25 MHz/n, where n is any positive integer. The master-slave operation may also cause trigger jitter.

Link Library

NI-SCOPE 2.1.4 and previous versions installed a duplicate version of the NI-SCOPE C link library called niscope_32.lib. This duplicate version has been obsoleted and now only niscope.lib is installed. Programs linking against the duplicate name need to be changed to link against niscope.lib.

Visual Basic

ViConstString, ViChar, and ViString are used as parameters for the NI-SCOPE functions. However, these types are invalid in Visual Basic. Visual Basic users should declare variables of type String.

IVI

The trigger type (NISCOPE_ATTR_TRIGGER_TYPE) for immediate triggering used to be returned as NISCOPE_VAL_EDGE (1). It is now returned as NISCOPE_VAL_IMMEDIATE_TRIGGER (6).
