TekScope Anywhere™ overview

As systems become more complex, solutions that are convenient to use outside the lab and that enable collaboration between sites and customers are needed. These needs range from easy ways to share data, the ability to run measurements outside the lab, and methods to correlation lab measurements with simulation results.

Collaborate

TekScope Anywhere™ runs on your PC, Enabling analysis of data captured in your lab. Sessions can easily be saved on your Tektronix Oscilloscope and recalled. In addition, to Tektronix waveforms other file formats are supported including, wfm, .isf, .csv, .h5, .tr0 enabling correlation.

Analyze

Measurement results use a common measurement library with your Tektronix oscilloscope so results correlate. TekScope Anywhere™ supports a range of measurements Including parametric, jitter and eye measurements. Plots can be customized and are interactive with Zoom and cursor controls allowing custom views to share.

Document

Results and views can be saved as a session file and archived for later use or sent to a colleague or supplier for a debug session. Alternatively, results can be archived and saved in .pdf or .mht format using the report generator. The report can be customized to include the information of interest including: configuration details, measurement results, and plots. Plot and measurement data can also be saved to a .csv format file for archiving or data analysis in external applications.

Collaboration and setup sharing

Sharing data acquired on the oscilloscope for offline analysis is easily supported with the TekScope session export utility and TekScope Anywhere™ offline analysis software. When sharing data for remote debug sessions or for archiving for future use it is often necessary to save the entire oscilloscope configuration including measurement configuration and waveform data. The session export utility on your Tektronix DPO/MSO5000, DPO7000C, or DPO/MSO70000C/D/DX/SX Series oscilloscope creates a single file with all the necessary information to recreate the setup for analysis using TekScope Anywhere™.

Reports for data archive

After analysis is complete a report can be generated to share or archive. Options, including the ability to include plots or configuration details, allow the user to specify the information that goes in the report. Reports can be archived as an .mht or .pdf file.

Waveform correlation between lab or simulation results

A common issue that arises when taking lab measurements is correlation between instrumentation and simulation. The source of differences can be related to a difference in measurement algorithms. TekScope Anywhere™ allows the user to import multiple waveform formats from different sources, including .wfm, .csv, .bin, .trc, and .tr0, enabling the use of common analysis tools, eliminating the differences due to differing analysis tools. For example, the user can simultaneously compare the eye opening of a waveform captured in the lab vs. a simulated waveform or waveform captured on a different oscilloscope.

Customizable display

Waveform analysis is no longer constrained to a single oscilloscope display, TekScope Anywhere™ allows the user to be in control of their analysis environment.

Two options are available for waveform viewing, overlay mode as shown in the image on the left or stacked mode as shown in the images below. The user can simply toggle between the two modes based on the required analysis. For example, when looking at edge crossings between two data signals, overlay mode may be preferred. As the number of waveforms grows, stacked mode is typically preferred.

Other scenarios require the evaluation of waveforms and plot data, including eye diagrams, spectrums, bathtub plots, or histograms. Plots can be viewed in the same window as the waveform or in cases where additional screen real estate is needed a group of plots can be created and displayed on a second monitor. Within the group of plots, the user has the flexibility to customize the layout by simply dragging and dropping the plots within the display. For example, as shown below when viewing the jitter spectrum or FFT of a waveform, a stacked view may be preferred. Alternatively, a side by side view is also possible.

Side-by-side view of eye diagram and waveforms shown in individual views

In the event that a single display is not sufficient to view the necessary plots, they can quickly be grouped and moved to a second monitor. Once grouped, the user has the flexibility to customize the layout and the ability to view the plots in either tabbed or grid mode. Tabbed mode provides a maximized view of an individual plot while allowing the user to click on the other tabs to toggle between the plots. Grid mode provides a single view of all the plots in the group. The following two images contain the same group of plots, however, the top image is in tabbed mode and the bottom image is in grid mode. The user can quickly toggle between the two modes using the icons on the group toolbar.

Waveform zoom and cursors

 

Interactive plots with zoom and cursors

Plots provide a deep level of understanding of system behavior. It is often desired to zoom in on plot data, some common reasons to zoom on plots include placing cursors to take measurements at precise locations on an eye diagram or to view jitter at a specific frequency. Many of today's high speed serial interfaces use Spread Spectrum Clocking (SSC), resulting in low frequency jitter around 33 kHz. By default a spectral plot will show the entire jitter content of the signal, however, it is often desired to look at a specific range of spectral content. Zooming enables precise viewing of the portion of the plot of interest. While zoomed in the overview window always provides context of the zoomed area in relation to the entire plot.

Cursor support for plots and waveforms can provide additional measurement details. For example, the eye height and eye width of a waveform can be determined using cursors, or the eye opening at a specific BER level can be determined by evaluating the bathtub plot.

 

 

Cursor measurements with prominent readouts provide quick results for both plot and waveform data

De-embed, Embed, and Equalize

With today's high speed serial interfaces, it is often necessary to apply post processing to the acquired waveform before measurements are taken. For measurements at the near end or transmitter output, it is common to de-embed the effects of the measurement circuit. Using SDLA Visualizer on a Tektronix 70K Series Oscilloscope, de-embed filters can be created and then used in TekScope Anywhere™.

Likewise, when doing far end measurements or measurements at the receiver, it is necessary to apply equalization and in some cases embed channel properties. CTLE equalization filters, created by SDLA Visualizer, can open closed eyes in TekScope Anywhere™.

Key capabilities

TekScope Anywhere is available in two versions: Basic and Advanced Jitter. The table below provides a quick summary of each version.

TekScope Anywhere with Advanced Jitter Analysis uses the same DPOJET measurement framework available on Tektronix oscilloscopes. Comprehensive jitter and eye-diagram analysis, along with decomposition algorithms, simplify the discovery of signal integrity and jitter problems in today's high-speed serial, digital, and communication system designs.
