Tektronix Inc. recently announced the expansion of its DPO70000SX Performance Oscilloscope Series to include 50 GHz and 23 GHz models. By extending our flagship 70 GHz model, the new 50 GHz product is ideal for engineers and researchers who want to take advantage of the superior low-noise performance of the patented asynchronous time interleaving (ATI) architecture for technologies such as 28 GBaud PAM4 and Kband frequency testing. The 23 GHz instrument joins the existing 33GHz models which feature compact dimensions and built-in scalability using the UltraSync synchronization technology.
The growing family of DPO70000SX Series Performance Oscilloscopes deliver the lowest-noise and highest fidelity of any ultra-high bandwidth real-time oscilloscope available on the market today. As speeds go up and amplitudes go down, system noise has become a major challenge because it obscures important details in signal behavior. Tektronix' 50 GHz and 70 GHz ATI oscilloscopes allow engineers to more accurately capture and measure higher frequency signals with up to 30% less system noise than the legacy frequency interleaving approaches used by other oscilloscope manufacturers.
Current real time scope solutions for digitizing ultra-high bandwidth signals distribute signal energy to two digitizing paths then use DSP to reconstruct the input signal. Unlike legacy schemes, Tektronix' unique ATI architecture uses a symmetrical technique that delivers all signal energy to both digitizing paths resulting in an inherent noise advantage when signals are reconstructed. The 50 GHz instrument's ATI channel offers 200 GS/s sample rate for 5 ps/sample resolution. It also has two standard (non-ATI) 33 GHz channels with 100 GS/s sample rate for 10 ps/sample resolution.
Precise multi-instrument timing synchronization is required for test applications such as validation of high-speed networking technologies used in long-reach fiber systems (DP-QPSK Coherent Modulation) and shorter-reach (PAM4) data center networks. The DPO70000SX oscilloscopes meet these needs through the patent-pending UltraSync architecture that provides precise data synchronization and convenient operation of multi-unit systems. UltraSync uses a 12.5 GHz sample clock reference and coordinated trigger for inherent channel-to-channel skew stability superior to channels within a single instrument.
Rounding out the DPO70000SX Series, Tektronix is also introducing a new 23 GHz model that takes advantage of the compact form factor and supports UltraSync. It features four 23 GHz non-ATI channels with a 50 GS/s sample rate on each, for 20 ps/sample resolution.
