This file contains information to introduce you to the LabVIEW 2012 Jitter Analysis Toolkit. This file also contains important information about the toolkit, including system requirements, installation instructions, new features, and known issues.
Upgrade and Compatibility Issues
Accessing the Toolkit and Help
Automating the Installation of NI Products
The LabVIEW Jitter Analysis Toolkit provides a library of VIs optimized for performing high-throughput, automated jitter, eye diagram, and phase-noise measurements. The toolkit is hardware-independent and can be used with NI high-speed and high-resolution digitizers as well as third-party oscilloscopes and digitizers.
In addition to the system requirements for the LabVIEW Development System, the Jitter Analysis Toolkit has the following requirements:
Refer to the LabVIEW Readme file in the labview directory for additional system requirements and supported operating systems for LabVIEW 2012.
You can install all of your LabVIEW products—including the Jitter Analysis Toolkit—using the LabVIEW 2012 Platform DVDs. Refer to the LabVIEW Installation Guide on the LabVIEW Platform DVD 1 for installation instructions and system requirements.
To request additional LabVIEW Platform DVDs, refer to the National Instruments website.
Note: If you purchased this product with an NI Software Suite or NI Product Bundle, use the installation media that shipped with your purchase to install this product.
The LabVIEW 2012 Jitter Analysis Toolkit introduces the following new features.
The Jitter palette includes the new RJ PJ Separation VI, which separates the random and periodic components of jitter in a jitter sequence and returns their RMS and peak-to-peak values.
Depending on how you acquire waveform data, the Y data values that are part of the waveform data type might be double-precision, floating-point numeric values or 8-bit signed integers. Analyzing waveforms represented by integers reduces the size of the data you must analyze, which requires less memory. The following VIs include polymorphic instances that can operate on the waveform data type when it contains double-precision floating-point data or 8-bit signed integers:
The LabVIEW 2012 Jitter Analysis Toolkit includes the following VI enhancements and behavior changes:
You might encounter the following compatibility issues when you upgrade to the LabVIEW 2012 Jitter Analysis Toolkit:
You can access the software and documentation known issues list online. Refer to the LabVIEW Toolkits Known Issues website for an up-to-date list of any known issues in the Jitter Analysis Toolkit.
The following items are the IDs and titles of a subset of issues fixed between the LabVIEW 2011 Jitter Anlaysis Toolkit and the LabVIEW 2012 Jitter Anlaysis Toolkit. This is not an exhaustive list of issues fixed in the current version of the Jitter Analysis Toolkit. If you have a CAR ID, you can search this list to validate the issue has been fixed.
| ID | Fixed Issue |
|---|---|
| 336767 | Clock Recovery (Mean Clock) VI returns error -20068 when processing certain waveforms |
| 334701 | Rj Dj Separation VI does not appear on the Jitter Analysis Toolkit palette |
| 334182 | Duty cycle distortion values yield inconsistent results |
| 321442 | The high state level parameter is miscalculated and yields results that are higher than expected |
| 288897 | Glitch appears in eye diagram even though actual waveform is correct |
| 288895 | Clock Recovery (Mean Clock) VI does not sufficiently estimate unit interval for Eye Data Generation VI |
| 285695 | Jitter Analysis Toolkit example VIs do not show up in Example Finder |
To access the Jitter Analysis Toolkit VIs, select View»Functions Palette from the block diagram in LabVIEW and navigate to the Addons»Jitter Analysis palette. You also can right-click any blank space on the block diagram to display the Functions palette.
Refer to the Toolkits»Jitter Analysis VIs book on the Contents tab of the LabVIEW Help for more information about the Jitter Analysis Toolkit.
Select Help»Find Examples from LabVIEW to launch the NI Example Finder. LabVIEW examples for the Jitter Analysis Toolkit are located in the labview\examples\Jitter Analysis directory. You can modify an example VI to fit an application, or you can copy and paste from one or more examples into a VI that you create.
You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes. However, starting with the August 2012 releases (products using NI Installers version 3.1 or later), you may need to perform additional steps before or during a silent installation of NI software.
If the NI product you are installing uses Microsoft .NET 4.0, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.0 separately before you install NI software.
