Tektronix high-performance oscilloscopes launch new favorites

Tektronix has added new products to its high-end oscilloscope series, the DPO70000SX high-performance oscilloscope series, with 50 GHz and 23 GHz models. Engineers and researchers can use the same ATI (Asynchronous Timing Interleaving) technology as the 70 GHz flagship product to achieve high-bandwidth, high-precision, low-noise testing of 28 GBaud PAM4 high-speed digital and Kband RF. The 23 GHz instrument joins the existing 33 GHz model, with a compact appearance, built-in expansion capabilities, and UltraSync synchronization technology.

The growing DPO70000SX Series family of high-performance oscilloscopes offers the lowest noise and highest fidelity of any ultra-high bandwidth real-time oscilloscope on the market today. As speeds increase and amplitudes decrease, system noise has become a major challenge because it blocks important details in signal characteristics. With Tektronix 50GHz and 70GHz ATI oscilloscopes, engineers can more accurately capture and measure higher frequency signals with up to 30% lower system noise than traditional frequency interleaving methods used by other oscilloscope manufacturers .

" The DPO70000SX Series sets a new standard for leading performance, and we are rapidly expanding the family in direct response to customer needs," said Brian Reich , general manager of high-performance oscilloscopes at Tektronix. "With our flagship model offering 10 percent more bandwidth, 25 percent higher sampling rate , and 30 percent lower noise than the nearest competitor , we look forward to expanding our portfolio to include even more engineers and researchers who are concerned about signal integrity."

Current real-time oscilloscope solutions for digitizing ultra-high bandwidth signals split the signal energy into two digitizing paths and then use DSP to reconstruct the input signal. Unlike traditional approaches, Tektronix's unique ATI architecture uses symmetrical technology to deliver all signal energy to both digitizing paths simultaneously, achieving an inherent noise advantage when reconstructing the signal. The ATI channel of the 50GHz instrument provides a 200 GS/s sampling rate for 5 ps/sample resolution. It also has two standard (non-ATI) 33 GHz channels that provide a 100 GS/s sampling rate for 10 ps/sample resolution.

To further enhance signal fidelity, the DPO70000SX oscilloscopes feature a compact 5 1/4" form factor so the instrument can be placed very close to the device under test (DUT), reducing cable lengths and providing cleaner signals. Its low height allows each oscilloscope to fit within a single 3U rack-mount space, or two oscilloscopes can be stacked in the same space as a typical benchtop oscilloscope.

Many test applications require precise multi-instrument timing synchronization, such as verifying high-speed network technologies used in long-haul fiber systems (DP-QPSK coherent modulation) and short-haul (PAM4) data center networks. The DPO70000SX oscilloscope's patent-pending UltraSync architecture provides precise data timing and convenient operation for multiple systems to meet these needs. UltraSync uses a 12.5 GHz sampling clock reference and coordinated triggering, and its own channel-to-channel delay is better than multiple channels within a single instrument.

The latest 400G Ethernet developed by the IEEE P802.3bs 400G ( generally 8 x 50G) electrical interface and optical interface working group will use PAM4 . Compared with the traditional NRZ using two-level signaling , the four-level scheme used in PAM4 significantly increases the signal complexity and puts forward new requirements for the performance and noise sensitivity of the test equipment.

The industry is planning multi-level signaling for deployment in future 56GBaud data communication standards, using a technology called PAM4 to support transmission distances up to 10km. Multi-level signaling presents unique measurement challenges for today's design engineers. To provide test insights related to this new technology, Tektronix has introduced PAM4 analysis support in the DPO70000SX family. The DPO70000SX 50 GHz and 70 GHz models provide the industry's best low-noise acquisition system to analyze PAM4 signaling characteristics with exceptional accuracy using this latest analysis tool.

To meet the emerging PAM4 modulation measurement needs, Tektronix has announced the industry's most comprehensive set of analysis tools, fully supporting both optical and electrical interfaces. The new tools run on the DPO70000SX70 GHz real-time oscilloscope and the DSA8300 equivalent-time oscilloscope, ensuring that no matter which instrument configuration is required, the correct results can be provided with the highest accuracy.

As the number of smartphone users and emerging applications such as the Internet of Things (IoT) continue to grow, the industry's demand for more data throughput is expanding. For this reason, the industry is accelerating the development of 5G networks to utilize unused frequency bands, such as the V-band, to transmit large amounts of data. Unfortunately, current test solutions for wide-bandwidth applications require complex setups involving multiple devices that must be calibrated frequently. In addition, these solutions introduce linearity issues and do not have the response flatness provided by solutions based on a single oscilloscope.

By implementing SignalVu software on its DPO70000SX ATI family of high-performance oscilloscopes, Tektronix is ​​enabling researchers and others developing next-generation wide-bandwidth and ultra-wide-bandwidth technologies such as 5G, cellular backhaul and radar to perform RF modulation measurements with unprecedented margins of error.

SignalVu software is integrated with the DPO70000SX platform, providing an attractive solution for customers who need to demodulate and analyze ultra-wide bandwidth signals up to 70GHz. For RF applications, Tektronix provides the widest bandwidth signal analyzer on the market, with outstanding signal fidelity and comprehensive analysis functions, including modulation and pulse analysis, supporting advanced commercial wireless standards such as 802.11ac and LTE. In addition, it can be used not only as a spectrum analyzer, but also as an oscilloscope.

The DPO70000SX70 GHz ATI oscilloscopes have the lowest noise and highest effective bits of any ultra-high bandwidth real-time oscilloscope available on the market. SignalVu takes full advantage of this signal fidelity to provide the industry's most accurate EVM measurements and other signal analysis capabilities, such as linear FM rates on linear FM radar systems up to 70 GHz.
