Low-noise, high-fidelity signal acquisition is critical for ultra-high bandwidth applications such as long-haul coherent optical communications, 400G data communications and broadband RF. The flagship DPO77002SX uses ATI (Asynchronous Timing Interleaving) architecture to deliver 70 GHz and 200 GS/s (5 ps/sample) real-time acquisition performance. The noise performance of this patented symmetric architecture is far superior to traditional bandwidth interleaving methods. DPO70000SX delivers the lowest noise, highest fidelity and maximum performance, supports complex optical modulation analysis, jitter and noise analysis for high-speed serial signaling and frequency, and phase and modulation analysis for broadband RF signals.

Conventional real-time oscilloscope solutions for digitizing ultra-high bandwidth signals split the signal energy across two digitization paths, and then use DSP to reconstruct the input signal. Unlike traditional solutions, Tektronix's proprietary ATI architecture features symmetric technology that delivers all signal energy to both digitization paths, delivering inherent noise advantages.

This diagram shows how the input signal enters the ATI ASIC, gets sampled, and is routed alternately to each digitization subsystem. The sampling clock runs at 75 GHz, effectively folding the spectrum of the input signal by approximately 37.5 GHz before digitization. Each digitization path operates at 100 GS/s, with the folded spectrum limited to <40 GHz, meeting Nyquist criteria. The alternating phase of the samplers inverts the signal phase by 180° in one digitization path, which provides significant advantages for reconstructing the final digitized signal.

By digitizing two full copies of signal energy, the signal spectrum is "unfolded" via DSP equivalent to the sampling process, then combined to reproduce the input signal. Since the two copies of the signal are combined together, this process effectively averages the signals, reducing random noise. The phase inversion introduced by the sampling process causes the intermediate frequency components to cancel each other directly, simplifying reconstruction and calibration.

Therefore, the ATI architecture provides inherent SNR advantages over traditional digital bandwidth interleaving technologies. Traditional technologies directly split an input signal into upper and lower frequency bands. This approach splits power: the upper band must be downconverted before digitization, while the lower band is digitized directly. This asymmetric method makes signal reconstruction and calibration much more difficult, leading to passband frequency or phase response errors. Power splitting eliminates the opportunity to reduce signal noise. ATI's unique symmetric architecture eliminates these problems.

By comparing the baseline noise of Tektronix DPO77002SX and a 63 GHz model from another manufacturer, with both instruments set to 60 GHz bandwidth, you can see that ATI delivers the lowest noise acquisition performance.

JNF Performance

The brand-new main sampling clock design delivers ultra-low 65fs RMS sampling clock jitter. Combined with ATI's ultra-low noise performance, it enables the DPO77002SX to achieve unprecedented jitter noise floor performance. At 300 mVFS the JNF is only 123 fsRMS, which can even match the performance of narrower bandwidth instruments.

This figure shows 60 GHz sine wave jitter analysis on the ATI input. The result displays a clean eye diagram with random jitter RJ <80 fsRMS.

The DPO70000SX Series Oscilloscopes feature a unique compact oscilloscope form factor that delivers unprecedented workspace utilization and universal mounting capability. The SX Series offers a distinctive approach to ultra-high bandwidth real-time acquisition, aligning with the trend of users shifting to large external monitors, increasing automation, and separating the workspace of data acquisition and data analysis.

The standalone DPO70000SX oscilloscope has a compact form factor, delivers the same functionality as the benchtop DPO70000DX, and is only half the height when equipped with an external display, keyboard and mouse. The SX Series oscilloscopes support installation of advanced analysis software, and can perform automated testing equivalent to benchtop oscilloscopes using either internal or external control functions.

The DPO77002SX 70 GHz ATI High Performance Oscilloscope offers one channel with 70 GHz, 200 GS/s acquisition performance or two channels with 33 GHz, 100 GS/s acquisition performance. This instrument includes one 70 GHz, 1.85 mm low-noise ATI input channel plus a universal TekConnect 2.92 mm input, compatible with general-purpose probing and signal conditioning options up to 33 GHz.

The DPO73304SX Oscilloscope offers two channels with 33 GHz, 100 GS/s acquisition performance or four channels with 23 GHz, 50 GS/s real-time acquisition performance. This model delivers similar acquisition performance to the benchtop DPO73304DX, but features an all-new compact instrument form factor.

All models in the DPO70000SX Series deliver the highest trigger performance available in real-time oscilloscopes, including >25 GHz edge trigger performance and<40 ps glitch trigger performance. The innovative window trigger type can trigger on the burst envelope of RF signals, and supports time qualification to distinguish envelope widths. The industry-leading pulse width timer performance enables the most accurate identification of specific bit widths in high-speed serial data streams, and detection of runt pulses in pseudo-random signaling. The auxiliary trigger input of the DPO70000SX Series provides low-jitter edge triggering, and is compatible with TekConnect accessories to support various signal conditioning solutions.

Optimal Ease of Use

Less Than Half the Height of Benchtop Instruments

The DPO70000SX series comes in a 5 ¼" (3U) form factor, which optimizes space utilization and provides the most versatile mounting configurations. The stacking height of two DPO70000SX instruments is lower than that of comparable-grade benchtop instruments, while delivering higher measurement performance.

Full-Featured Standalone Oscilloscope

Despite the compact form factor, SX models deliver full standalone oscilloscope functionality and performance. They can directly run Tektronix advanced analysis applications for jitter, noise, optical modulation and spectrum analysis without requiring a separate processor or control unit.

2 x 70 GHz, 4 x 33 GHz configuration with monitor and auxiliary front panel

Provides Familiar Oscilloscope Controls On Demand

The DPO7AFP Auxiliary Front Panel is an important practical accessory that complements the compact instrument form factor, allowing users to operate with familiar controls without needing to access the front of the instrument.

The auxiliary front panel provides the same control configuration as a standalone USB peripheral (embedded in DPO/DSA/MSO7000/70000 benchtop instruments). This accessory enhances instrument usability even when the main front panel is blocked by the installation location.

Remote Desktop Operation

Like current DPO/MSO70000 Series benchtop instruments, the DPO70000SX can be operated remotely over a network via Windows® Remote Desktop. Access your oscilloscope from your lab or anywhere in the world with the Remote Desktop tool.

Precise Synchronization for Multi-unit Systems

DPO70000SX Series instruments include Tektronix UltraSync multi-instrument time synchronization bus. UltraSync is used to synchronize sampling clock, trigger and run/stop control across multiple instruments, delivering performance identical to that of a single oscilloscope. UltraSync cables are available in 1-meter and 2-meter lengths, which maximizes the versatility of configuration and layout while maintaining timing integrity for multi-instrument systems.

The UltraSync bus consists of three elements, each providing an essential function for precision multi-instrument operation:

• UltraSync includes a 12.5 GHz sampling clock reference signal provided by the master unit, which is used by each expansion unit to synchronize sample placement in the digitization process.

• The trigger bus provides run/stop control for all units in a multi-instrument configuration, allowing either the master or an expansion unit to act as the trigger source.

• Control and data transfer from expansion units to the master unit is managed via a PCIe Gen 2 x4 link, supporting a data transfer rate of 2 GB/s.

When operated in a multi-instrument configuration, one DPO70000SX acts as the master unit, controlling one or more units running in expansion mode. Any DPO70000SX oscilloscope can operate either as a standalone oscilloscope, or act as a master or expansion unit in a multi-unit configuration. The role is determined by the UltraSync cable, no additional components are required. Users can decouple the multi-unit configuration at any time to operate the instruments independently, with no requirement for additional control units or other accessories. Multiple independent oscilloscopes can also be easily combined by adding UltraSync cables between the master and expansion units.

During multi-unit configuration startup, the configuration manager software verifies the master-expansion unit cabling, and provides graphical feedback if there are missing components or configuration errors. After verification, the TekScope user interface is displayed, with master and expansion units pooled together for display and analysis using built-in functions and advanced analysis applications.

Scalable Performance and Common Configuration

The DPO70000SX multi-unit mode delivers scalable performance for increased channel count configurations. The master-expansion configuration provides additional synchronized input channels with the same precision as internal channels, and is controlled as a single interactive instrument from one user interface, or via a programming interface for automated applications.

With this performance-scalable approach, users can purchase the performance that meets current requirements, such as four 33 GHz, 100 GS/s acquisition channels, or start with two channels of 70 GHz, 200 GS/s performance for next-generation designs. Additional units can then be added to achieve four 70 GHz, 200 GS/s channels. The units in this four-unit configuration can be deployed individually in pairs, or as standalone units at any time to meet other test requirements.

DPO77002SX also delivers exceptional value for single-channel 70 GHz, 200 GS/s applications such as RF analysis or pulsed laser research. In these cases, users can purchase one oscilloscope that delivers 70 GHz channel performance plus two 33 GHz channels. Additional units can be purchased later when more channels are required, and combined together using UltraSync.
