Contact Information ============================================================================= 1. Revision History v2.0.0 was the original release for the "v2" generation of TDSJIT3. v2.0.1 makes a few corrections to the On-Line Help and to the printable version of the manual (TDSJIT3v2.pdf). v2.1.0 constrains time trend plots to the upper half of the display. v3.0.0 Adds support for DPO7K scopes. Clock-Data-TIE measurement added. v3.0.1 Adds support for DPO70K, DSA70K. Continues support for DPO7KK, TDS and CSA scopes. ============================================================================= 2. System Requirements - A software security key is generally needed to enable these applications. The software offers five (5) free trials for evaluation. Once the five free trials are exhausted, a software security key may be purchased from Tektronix to permanently enable the software application on your oscilloscope. - The TDSJIT3A and TDSJIT3E applications are compatible with all four- channel DPO70K, DSA70K, DPO7K, TDS7KB, TDS7K, CSA7KB, TDS6KB, TDS6KC and TDS5KB series oscilloscopes. - The application requires latest TekScope Software. The latest Tekscope Software can be found using the myTek software and firmwavre finder from Tektronix website. http://www.tek.com/site/sw/search/ - The application requires the Windows 2000 or Windows XP operating system. - The latest version of the TekScope drivers can be downloaded from Tektronix website at http://www.tek.com/Measurement/scopes/index.html. Click on "Software & Drivers" under the "Resources" set of links on the left. - Sun Microsystems' Java Runtime Environment (JRE) version 1.4.2_04 is required for this release; it will automatically be installed with TDSJIT3A and TDSJIT3E if they are not already on your oscilloscope. If the JRE is deleted, restore it through the TDSJIT3A and TDSJIT3E installation. - 512 MB or more of (windows) system memory is required. 1GB is highly recommended, particularly if the scope has extended acquisition memory. - Disk space requirements: * Installation files: installing this application and its on-line help requires ~30 MB * JRE virtual memory: The Jave Runtime Engine (JRE) is given an upper limit that depends on the amount of windows memory installed. This will directly impact the minimum allowable size of the windows virtual memory (swap space). If the amount of physical windows memory in the scope is modified, TDSJIT3A or TDSJIT3E should be reinstalled so that the JRE memory limits are properly updated. - Keyboard: Save/Recall, Statistics, Measurement, and Waveform Logging features require the use of a keyboard to enter file or folder names. - Mouse: Though a mouse is not required, we highly recommend its use with this product. - The best MS Windows(TM) task bar settings for running this application with a mouse but without a keyboard are: Always on top = checked Auto Hide = checked When the application is used with a mouse only, this allows you to access previously minimized plots from the task bar while keeping its visibility to a minimum. This change should be done prior to starting TDSJIT3v2 or the position or the application will not be entirely in the lower half screen. ============================================================================= 3.

New Features v3.0.1 * Support DPO70K, DSA70K, DPO7K, TDS and CSA scopes. v3.0.0 * Support DPO7K scopes. * Clock-Data-TIE measurement added * Trend plots are no longer constrained. * Fixes several defects including: - GPIB query for Rj/Dj resultFor All returns Current values - 'E806 Pattern Length Error'is inappropriate for arbitrary pattern method - On line help: *ESR? recommended to prevent queue overflow - RECALL Setup files crashes app - Repeating RjDj separation throws warning when filter is turned on - Jitter on Arbitrary pattern bad when leading bits change on 2nd acq v2.1.0 * Constrained Trend Plots v2.0.0 The following features have been added to TDSJIT3v2 Advanced: * High-pass and low-pass measurement filters * Rj/Dj separation for arbitrary (i.e. non-repeating) data patterns * Phase-noise plots * Transfer-function plots * More complete support for 2nd-order PLL clock recovery The following features have been added to both TDSJITv2 Advanced and TDSJIT3v2 Essentials: * A measurement wizard to assist new or infrequent users * Improved vertical and horizontal autoset * Automatic control of voltage reference levels * Averaged and Peak-Hold modes for frequency-domain plots * Logarithmic horizontal axis option for frequency-domain plots * Main user interface can be undocked and moved to a second monitor * Plot enhancements: - Cursor control via the scope's general-purpose knobs - Export to scope reference channels (except for Time Trends) - Resizable plots (except for Time Trends) ============================================================================= 5. Known Issues * This application is extremely computationally intensive and is a heavy consumer of memory and disk resources. If record lengths of 40 Meg or greater are acquired and analyzed, the number of measurements should be limited to no more than four, with no more than one Rj/Dj Analysis operation enabled at a time. It may be necessary to increase the Windows virtual memory settings. At times when the processing load is extremely high, the blinking status indicator in the lower right corner of the user interface may stop blinking for up to a minute, giving the appearance that the application or the scope is hung. If allowed, they will normally recover and complete the analysis without intervention. * The configuration of any measurement filters is not included in log files. * User accounts that are set up as restricted users may not be able to save setup files. * When the application is undocked (File->Undock) and the scope user interface returns to full-screen, it can come to the foreground and obscure the TDSJIT3A or TDSJIT3E user interface. If this happens, use alt-tab to bring TDSJIT3A or TDSJIT3E to the foreground or minimize the TekScope interface (File->Minimize), move the TDSJIT3A or TDSJIT3E interface to a second monitor, and then restore the TekScope interface. * When using a secondary monitor, the "Colors" setting [Display Properties > Settings] of the secondary monitor must match those of the Scope's LCD Display. * Many versions of scope firmware allow four separate zoom windows. The TDSJIT3A or TDSJIT3E application does not support four zoom windows for its zoom-gating function. If using this function, we recommend that you only use the first zoom window while operating TDSJIT3A or TDSJIT3E. * A query following the GPIB command 'variable:value "resultFor","measN"' should return "Busy" until the command is complete. The query instead may cause a GPIB time-out. If this occurs, we recommend that you wait one second after sending the command before reading results, instead of polling for a Busy response. ============================================================================= 6. Installation Normally, the TDSJIT3A/TDSJIT3E application resides on the hard drive of your oscilloscope. If the application is not installed on the hard disk, perform the following steps to install the application from the Optional Applications Software on a Windows-Based Oscilloscope Compact disc (CD-ROM): 1. If the mouse is not installed, connect it to the oscilloscope or use the touchscreen (if available). 2. Power on the oscilloscope to start Windows. 3. Install the optional applications software CD in the CD-ROM reader of the oscilloscope. 4. The autorun utility will start the installation program. If the autorun utility doesn't start up automatically, browse to the CDROM and double-click the launch.exe. 5. Select the option 'Jitter and Timing Analysis'. Note that the installation process installs both TDSJIT3v2A and TDSJIT3v2E. 6. Follow the instructions given by the InstallShield Wizard. If the Java Run-time Environment (JRE 1.4.2) software is not currently installed then the InstallShield Wizard will prompt to install it. Click "OK" when prompted for installing JRE 1.4.2 and accept all defaults in the JRE's installation wizard, however, if prompted to reboot after JRE install, select No. 7. The oscilloscope must reboot to complete the installation process. 8. You may need to enter the authorized Option Installation Key to enable the application. The key is specific to the serialized oscilloscope and options for which it was purchased. To enter the key number, follow these steps: a. Maximize the oscilloscope user interface if it is currently minimized. b. If the oscilloscope is in the toolbar mode (default), select the Menu button (upper right corner of the display) to put the oscilloscope into menu-bar mode. In menu-bar mode you should see a PC-style menu across the top of the display. c. Go to the Utilities menu in the menu bar and select Option Installation. d. Follow the on-screen instructions to enter the alphanumeric key number exactly as it is printed on the rear-panel label. The TDSJIT3A / TDSJIT3E application is now ready for use. Depending on your scope model, it can be found on the File->Run Application or App or Analyze menu. You may install and later uninstall TDSJIT3A/TDSJIT3E on your oscilloscope without affecting an existing installation of TDSJIT3. If the amount of physical windows memory on the oscilloscope is modified, you must reinstall TDSJIT3A/TDSJIT3E so that the application is optimally configured to use the memory. ============================================================================= 7.
