Accelerate the Debug of Complex Electrical Designs

FastAcq Acquisition Mode Expedites Debugging by Clearly Showing Imperfections
More than just color-grading, FastAcq’s proprietary DPX® acquisition technology captures signals at more than 300,000 waveforms per second on all four channels simultaneously, dramatically increasing the probability of discovering infrequent fault events. And with a simple turn of the intensity knob you can clearly “see a world others don’t see,” displaying the complete picture of your circuit’s operation. Some oscilloscope vendors claim high waveform capture rates for short bursts of time, but only Tektronix oscilloscopes, enabled by DPX technology, can deliver these fast waveform capture rates on a sustained basis – saving minutes, hours or even days by quickly revealing the nature of faults so sophisticated trigger modes can be applied to isolate them.

The Ability to Trigger an Oscilloscope on Events of Interest is Paramount in Complex Signal Debug and Verification
Whether you’re trying to find a problem signal or need to isolate a section of a complex signal for further analysis, like a DDR read or write burst. Tektronix’ Pinpoint® triggering provides the solution. The Pinpoint trigger system uses Silicon Germanium (SiGe) technology to provide very high trigger sensitivity with very low trigger jitter and ability to capture very narrow glitches. Pinpoint triggering allows selection of virtually all trigger types on both A and B trigger events. Other trigger systems offer multiple trigger types only on a single event (A event), with delayed trigger (B event) selection limited to edge type triggering and often do not provide a way to reset the trigger sequence if the B event doesn’t occur. But Pinpoint triggering provides the full suite of advanced trigger types on both A and B triggers, logic qualification to control when to look for these events, and reset triggering to begin the trigger sequence again after a specified time, state, or transition so that even events in the most complex signals can be captured. Other oscilloscopes typically offer less than 20 trigger combinations; Pinpoint triggering offers over 1400 combinations, all at full performance.

With Enhanced Triggering, trigger jitter is reduced to <100 fs. With this stability at the trigger point, the trigger point can be used as a measurement reference.

Protocol and Serial Pattern Triggering
To debug serial architectures, use the serial pattern triggering for NRZ serial data stream with built-in clock recovery and correlate events across physical and link layers. This feature comes standard on the DSA70000B series and is available on DPO70000B models as Opt. PTH. The instrument can recover the clock signal, identify transitions and allow you to set the desired encoded words for the serial pattern trigger to capture. Opt. PTH and the DSA70000B Series cover serial standards up to 3.125 Gb/s. For higher bit rate standards like USB 3.0, option PTU on the DPO70000B series and option STU on the DSA70000B series extend 8b10b triggering and decode to 5 Gbps.

Pattern Lock Triggering adds a new dimension to NRZ serial pattern triggering by enabling the oscilloscope to take synchronized acquisitions of a long serial test pattern with outstanding time base accuracy. Pattern lock triggering can be used to remove random jitter from long serial data patterns. Effects of specific bit transitions can be investigated and averaging can be used with mask testing.
This feature supports up to 6.25 Gb/s NRZ serial data stream and is standard on the DSA70000B instruments, or included as part of Option PTH on the DPO70000B models.

Large 10-Division XGA Display Screen
The DPO/DSA70000B Series have a large 12.1” (307.3 mm) XGA display with a touch screen with 10 vertical divisions give you 25% more vertical measurement resolution than other oscilloscopes.

Unmatched Usability
TekLink™ allows you to acquire more than four channels by synchronizing multiple oscilloscopes and debug multiple-lane high-speed applications such as PCI Express X16 or DDR memory.

The DPO/DSA70000B Series instruments excel in usability with a suite of productivity features, such as a touch screen, flat menu structures, intuitive graphical icons, knob-per-channel vertical controls, right clicks, mouse wheel operation, and familiar Windows-based controls.

Interoperability with Logic Analyzers for Digital Design and Debug 
Tektronix’ Integrated View (iView™) data display enables digital designers to solve signal integrity challenges and effectively debug and verify their systems more quickly and easily. This integration allows designers to view time-correlated digital and analog data in the same display window, and isolate the analog characteristics of the digital signals that are causing systems failures. No user calibration is required. And once set up, the iView feature is completely automated.

Unmatched Versatility

Get the Most of Your Oscilloscope by Fully Controlling its Waveform Acquisition and Display Parameters
Choose the operation you need to do your job the fastest: Automatic, Constant Sample Rate, or Manual. When you are doing signal exploration and want a lively signal, the default Automatic mode provides you with the liveliest display update rate. If you want the highest real-time sample rate that will give you the most measurement accuracy, then the Constant Sample Rate mode is for you. It will maintain the highest sample rate and provide the best real-time resolution. Finally the Manual mode ensures direct and independent control of the sample rate and record length for applications requiring specific settings

With the MyScope® Feature, Create Your Own Control Windows with Only the Controls, Features and Capabilities that You Care About
Easily create your own personalized “toolbox” of oscilloscope features in a matter of minutes using a simple, visual, drag-and-drop process. Once created, these custom control windows are easily accessed through a dedicated MyScope button and menu selection on the oscilloscope button/menu bar, just like any other control window. You can make an unlimited number of custom control windows, enabling each person who uses the oscilloscope in a shared environment to have their own unique control window.

MyScope control windows will benefit all oscilloscope users, eliminating the rampup time that many face when returning to the lab after not using an oscilloscope for a while, and enables the power user to be far more efficient. Everything you need is found in one control window rather than having to constantly navigate through menu after menu to repeat similar tasks.

With OpenChoice® Software, Customize Your Test and Measurement System with Familiar Analysis Tools
The analysis and networking features of OpenChoice software add more flexibility to Tektronix’ Windows XP oscilloscopes: Using the fast embedded bus, waveform data can be moved directly from acquisition to analysis applications on the Windows desktop at much faster speeds than conventional GPIB transfers. Tektronix’ implementation of industry standard protocols, such as TekVISA™ interface and ActiveX controls, are included for using and enhancing Windows applications for data analysis and documentation. IVI instrument drivers are included to enable easy communication with the oscilloscope using GPIB, RS-232, and LAN connections from programs running on the instrument or an external PC. Or, use the Software Developer’s Kit (SDK) to help create custom software to automate multistep processes in waveform collection and analysis with Visual BASIC, C, C++, MATLAB, LabVIEW, LabWindows/CVI, and other common Application Development Environments (ADE). Integration of the oscilloscope with external PCs and non-Windows hosts is also supported.

In addition, the OpenChoice architecture provides a comprehensive software infrastructure for faster, more versatile operations. Data transfer utilities, such as the Excel or Word toolbar plug-ins can be used to simplify analysis and documentation on the Windows desktop or on an external PC.
