Release Notes for the latest release: - Do not use 'AutoShape MaskHits' custom measurement name on MaskHits measurement. - In Composite Jitter Histogram plot, the RJ+NPJ histogram values and RJ Trend are analytical values when Rj is locked. - All newer plots will support only color mode in Reports. - DPOJET initializes with the ‘Jitter Only’ analysis method selected. The ‘Jitter + Noise’ analysis method may be selected from the DPOJET Preferences menu. - If the DJAN option is not enabled, the 'Jitter + Noise' analysis method may still be selected. This causes analysis to be performed using the full Jitter + Noise model, even though noise measurements are not available to the user. This may be desirable in order to compare/correlate jitter results with peers using a scope with the DJAN option. - If the Jitter Decomposition Analysis Method is changed to Jitter+Noise, applications that use DPOJET as a processing engine may give different results. Applications are qualified using the Jitter Only method. - A maximum of 8M unit intervals may be analyzed per waveform. Additional UIs are ignored. - When the Arbitrary Pattern method is used, the maximum window length is 24 for the Jitter-only analysis method, and 17 for the Jitter + Noise method. - The current release assumes the statistics of crosstalk are uniform across the horizontal dimension of the eye. The accuracy of BER contours and related measurements may be reduced if cyclostationary uncorrelated noise is substantial. - Ringback: Sometimes an eye diagram can partially close in the middle due to noise, resulting in two open eyes. In this case, the wider of the two openings should be reported. DPOJET is currently reporting from the left edge of the left eye to the right edge of the right eye. - With Explicit Clock whenever the TIE on the Right and Left Side of Eye are not Symmetric, the Eye Width result do not correlate with the Eye Width plot. This issue has been fixed. - OPTION LEVELS of DPOJET DPOJET is available in three versions, known as DPOJET Essentials, DPOJET Advanced (DJA) and the latest one Noise Analysis Tools(DJAN). All the 3 versions are installed by default; a software security key determines which version is run. - FLOATING LICENSE Click the Install button next to Floating License during installation. For more details please refer to TekScope OLH. - FREE TRIALS Free trials in the form of Floating trial license is supported. Earlier form of 10 Free trials is no longer supported. - Incompatible DPOJET plugins will no longer throw a pop-up during TekScope launch and instead it will say incompatible in the About DPOJET. ======================================================================================================================================================================= 5. Older Release Notes - This software applies to: MSO5034, MSO5054, MSO5104, MSO5204, DPO5034, DPO5054, DPO5104, DPO5204, MSO5034B, MSO5054B, MSO5104B, MSO5204B, DPO5034B, DPO5054B, DPO5104B, DPO5204B, MSO71254C, MSO71604C, MSO72004C, MSO70804C, MSO70404C, MSO70604C, MSO70404C, MSO70604C, MSO70804C, DPO71254C, DPO71604C, DPO72004C, DSA71254C, DSA71604C, DSA72004C, DSA70804C, DPO70804C, DPO7254C, DPO7354C, DPO70404C, DPO70604C, DPO7054C, DPO7104C, DPO70404C, DPO70604C, DPO70804C, DSA70404C, DSA70604C, DSA70404C, DSA70604C, DSA70804C, DPO72504D, DPO73304D, DSA72504D, DSA73304D, DPO72304DX, DPO72504DX, DPO73304DX, MSO72304DX, MSO72504DX, MSO73304DX - SOFTWARE COMPONENTS DPOJET is powered by MATLAB Software. MATLAB is a registered trademark of The MathWorks, Inc. Tektronix' limited rights to the deployment of MATLAB are governed by a license agreement which can be found in the following directory: C:\Program Files\MATLAB\MATLAB Compiler Runtime\v80 - SWITCHING BETWEEN APPLICATIONS * It is possible to switch between DPOJET and some other applications while retaining measurement setup and results. However, DPOJET's sequencer must be idle (not in the process of making measurements) before switching. Switching while measurements are running may cause the system to stop responding. Likewise, any other application's sequencer must be idle before switching back to DPOJET. * Switching between DPOJET and DPOPWR requires that the oscilloscope application (TekScope) be restarted. You will be offered a chance to cancel such an operation. The two applications cannot run concurrently. - HARD DISK SPACE AND FRAGMENTATION * The required memory space for double-precision advanced measurement results and intermediate results representing up to 99 measurements, for long-record length waveforms, far exceeds the addressable physical RAM . For this reason, results are cached as necessary to hard disk. * The binary files used to store results are located at " "C:\ProgramData\Tektronix\TekScope\wfmObj on 64 bit scope Some of the required objects are allocated when the TekScope application is launched. Remaining objects are only allocated when needed. This saves disk space since many users will never approach 99 measurements. Once instantiated, the file objects are never deleted, so they reserve disk space for future measurement instantiation. * Substantial hard disk space is required for the wfmObj directory, with some dependence on the number and type of measurements simultaneously used. In the worst case, this can exceed 30 GB in addition to the 6 GB allocated to store scope waveforms (channels, math’s and reference wfms). If the hard disk becomes too full before these objects are allocated for the first time, the application could be prevented from creating them. Fragmentation of the disk can also aggravate efficient memory allocation. Periodic de-fragmentation of your hard drive can help avoid problems. - PLOT LENGTH LIMITATIONS * For any waveform with greater than 20 million samples, only the first 20 million samples are used for associated eye diagrams and waveform plots. * A maximum of 10 million time trend points may be plotted. These may be in a single time trend plot or distributed across multiple plots. A partial plot may result when the 10 million allocation is reached. Data array plots draw from the same allocation of 10 million points. * Frequency-domain plots (Spectrum, Transfer Function and Phase Noise) are based on an FFT of, at most, 4 million points. * Eye diagrams are limited to 500 points of horizontal resolution, and the horizontal scale normally adjusts automatically to provide about two unit intervals across the diagram. If the horizontal time scale is manually set to less than 1/500th of a unit interval, then the eye diagram will be unable to display a full unit interval. ======================================================================================================================================================================= 6. Existing - Known Problems and Limitations - Name of "Height @ BER" measurement is changed to "Height @BER", old setup file containing this measurement will not be recalled. User need to update setup file. - Please make sure while saving the report, do not give any space in the file name/path. This can cause unusual characters to appear in the report, for the unicode used in the some measurements. - Follow the steps in Online Help->References-> Using digital channels, to configure the digital bus setup, CAS Min and Max. These values are important to get the correct Marks for READ and WRITE bursts and the post processing (DDRA) measurements depends on it. This will help you to configure CAS Min and Max correctly. - Sometimes the zoom feature for min and max statistics may not work. - When using the Report Append feature, make sure the hard disk has enough space. Otherwise you cannot use the Report feature. - When you get an error message as 'Internal measurement error. Please remove a measurement and try again.’ The possible reason is the application was not be able to process the configured measurements due to the high memory usage. You need to exit the TekScope and re-launch it to make it working. - In certain cases of PCIe analysis the Mask is incorrectly placed relative to the eye diagram, resulting in an obviously pessimistic result. A work around based on the use of oscilloscope channel deskew is available; please contact your Tektronix representative for details. - If Tekscope firmware releases earlier than that listed in Section 1 are reinstalled it may become necessary to reinstall DPOJET or the reinstallation could result in a loss of DPOJET functionality. - When using the query :DPOJET:MEAS:NAME? over the programmable interface, some commands return names containing non-ASCII characters that may affect readability (both human and machine). It is recommended that the query :DPOJET:Meas:TYPE? be used instead if this is a problem. - It is normally possible to concatenate GPIB commands sent on the programmable interface, for example ":DPOJET:ADDMEAS TIE; DPOJET:NUMMeas?". However, some commands don't operate sequentially when sent in this fashion; particularly when a file recall is followed by a query. It is recommended that care be taken if more than one command / query is sent per line. - When performing channel deskew from within DPOJET, both selected sources must be turned on manually prior to running the deskew. - When performing a measurement on a math waveform that relies on another math expression rather than a live source (for example, Period(MATH1) where MATH1 = arbFilt(MATH2) and MATH2 = CH1 - CH3), the reference level autoset code will fail to recognize that an acquisition must be triggered. Try to avoid math-on-math expressions. For the above example, use Period(MATH1) where MATH1 = arbFilt(CH1 - CH3). - If the scope is driven far into interpolated time (< 1ps/sample) and an eye diagram is created, the eye's horizontal scale becomes corrupted if more than one acquisition is accumulated. (This is a corner case since such a horizontal setting wastes record length and offers no benefits.) - On some machines the DPOJET mht reports may give a security warning when attempting to load from disk. This is because of mht report is using the recent versions of MIME OLE and it cannot run active content. - De-Emphasis measurement may not give the results,if a wrong clock recovery technique is used. - On receiving a Stop request, DPOJET will complete the measurement processing and then come to a stop. If the selected measurements are computationally intensive, the animated icon and red button in the DPOJET user interface may return to the stopped state before processing is actually complete. In these cases, the programmable interface (e.g. via “DPOJET:STATE?”) will also incorrectly report that DPOJET is finished. If DPOJET is stopped using the scope’s front-panel “Run/Stop” button, the animated icon and DPOJET sequencer button will properly reflect when processing is complete. Likewise, if the scope’s remote stop command (“ACQUIRE:STATE 0”) is used to stop DPOJET, then DPOJET’s remote state query (“DPOJET:STATE?”) will properly reflect when its processing is complete. - Mask hits are shown only for the first eye diagram plot if 4 plots are configured. - When High Performance Eye Rendering is enabled (default), Mask hits are counted only for the bits rendered into the eye, typically 8000 or less. To count ALL mask hits in the waveform, turn off High Performance Eye Rendering. - The application might hang, if there is any user interaction with the Scope graticule when DPOJET vertical autoset is in process. - Spectrum plot may not yield correct results when multiple qualifier zones are present. - Zoom and Cursor gating is not supported for Bus Measurements. - While running the PCE3 measurements in FREE Run mode, it is recommended to remove the Q-Bathtub and Q-PulseWidth plots and run. Some exceptions might be reported if the plots are displayed. - 30 GB or more of free disk space for file-backed data objects created when performing up to 99 measurements on long-record length waveforms. - While adding measurements or sequencing, if there is not enough disk space available, the following warning message is shown On 64-bit scopes: "Low Disk Space.Please close Tekscope and run the DiskFree utility located at "C:\Users\Public\Tektronix\TekApplications\DPOJET\Tools. The user is advised to close the application and run the DiskFree utility available at the location specified in the message above. - Export to Ref waveforms takes long time for record length > 100M. Sometimes this may lead to application hang. - Global configuration population limit for Period measurement has minimum value 1 and maximum value 2.1475G, during GPIB programming please do not set population limit higher than 2.1475G as this would result in overflow and value will be set to 1. - When RJ/DJ processing is manually configured to the Repeating Pattern method, the results panel’s Pattern Length field will display the user-specified length rather than the detected length. - When RJ/DJ processing is manually configured to the Arbitrary Pattern method, the results panel’s Pattern Length field will display a length that may not be related to the current waveform. - The bathtub plot is sometimes offset horizontally or appears blank. - If all measurements have Math only sources, during multiple "Single" sequencing, spurious error message "Not enough edges for Clock Recovery in current sequencing cycle" is logged with red X icon on results panel window but it does not affect any measurement accuracy. - Bit Rate and pattern length is not computed for measurements that do not require CDR. When only such measurements are selected, in some measurement combinations, bit rate is reported as "0.00 b/s". - When visual trigger is turned ON, source autoset (Vertical / Horizontal autoset) hang is observed some times. To overcome this, please turn OFF visual trigger before source autoset and turn it ON later. - In Serial Data Wizard, Source Autoset is ignored on only Math sources. - Record Length support details: ****************************** The DPOJET can support maximum RL supported by scope model however the DPOJET processing is determined by number UIs in the acquired waveform. More details are as follows. - When the number of measurements added in DPOJET are <= 5, then DPOJET supports processing of 37.5M UIs in each acquisition. - When the number of measurements added in DPOJET are > 5, then DPOJET supports processing of 10M UIs in each acquisition. Plots computation always processes up to 10M RL/UIs in each acquisition. ======================================================================================================================================================================= 7.
