Test & measurement
Precision is a foundational need, but intuitive application software and user interface have the same importance in order to trust what the measurement equipment presents. For this reason, several trusted tools for jitter analysis and decomposition, primarily used for signal integrity and channel modeling have been redesigned and optimised according to the needs expressed by the most demanding engineers seeking innovation in serial networking architectures. Embedding and de-embedding components in test paths requires application software that intuitively allows the ability to insert or remove a known or simulated channel (interconnect, cable, connector, via, etc.) into a system model to predict how a device performs under real-world conditions. The 7 Series DPO starts by accurately acquiring signals of interest, then powerful, flexible software tools enable the inclusion of S-parameters within a user- defined workflow, integrating models of components in the signal path. It provides the ability to place test points where virtual probing can occur and real-world measurements can be achieved. This is critical to successful compliance tests on many high- speed serial technologies. The new 7 Series DPO also features the new QuietChannel technology, that applies active equalization to compensate for high-speed signal loss, reducing noise and increasing measurement fidelity and ENOB—even for low-amplitude signals.
CAPTURING THE INVISIBLE PHYSICS CHALLENGES
Signal Integrity is not the only context where oscilloscope noise floor; dynamic range and ENOB are essential. In cutting-edge physics research — from high-energy particle detectors to quantum instrumentation, plasma diagnostics, and ultrafast laser labs — we often deal with extremely fast, high-dynamic-range, single-shot or repetitive pulses. Capturing these signals accurately is not just a matter of bandwidth or sample rate. The real challenge is how much usable information we can preserve in the digital domain with regards to their amplitude resolution. The new 7 Series DPO is perfect for resolving sub-nanosecond transitions on

mission-critical single-shot events, where efficient digital and analogue triggers are critical. Modern physics research labs, however, still prefer to use the oscilloscope for capturing and digitising while processing data externally. The 7 Series DPO is designed to enable this via an ultra- fast data transfer with its 10GbE SFP+ port and the support of gRPC protocol through TekHSI (High Speed Interface), a high performance, open-source universal Remote Procedure Call (RPC) framework.
FROM LAB BENCH TO RF BATTLEFIELD In test scenarios needing to analyse complex radio frequency (RF) systems across multiple domains — time, frequency, modulation, and sometimes even protocol or spatial domains — using multiple synchronised channels, the oscilloscope has become an ideal solution. Application scenarios like MIMO (Multiple- Input, Multiple-Output), beamforming, and phased array radar systems require multichannel RF analysis, capturing and analysing signals from multiple RF channels simultaneously. High vertical resolution, a low noise floor and precise timing synchronisation across channels to correlate behavior are key hardware requirements. The Tektronix 7 Series DPO includes
them all and provides true Multi-Domain Analysis in a unified interface called SignalVu-PC. SignalVu-PC enables deep correlation of events across domains and channels; its multi-window, multi-channel layout enables independent control of settings for each channel and synchronised domain views. With SignalVu-PC, the 7 Series DPO becomes an essential tool for validating modern wireless and radar systems when correlated insights on multiple signals are necessary. Modern oscilloscopes from Tektronix include the award-winning TekScope user interface. The 7 Series DPO becomes part of this full portfolio approach, adopted by Tektronix to cut learning curves, and puts intuitive tools at the center of system debug and validation activities. The UI looks immediately familiar, and it is great for simplifying complex setup and measurement. Modern engineers are collaborating across regions even more and will benefit from a simplified approach to scripting and automation. The 7 Series DPO supports all Python libraries designed to simplify and standardise the way developers interact with their lab equipment. This is a fundamental enabler for a measurement tool that often works 24/7, either by running long compliance test sessions or digitising physical phenomena over a long period of time. The 7 Series DPO is available as standard with an Embedded OS (Windows 10 is optional) and is designed for applications such as high energy physics, signal integrity and high-speed serial compliance and debug, as well as Multi Channel RF. The 7 Series DPO supports up to 125GS/s per channel and a maximum bandwidth of 25GHz. Main differentiators are the incredible linearity and low noise floor of the front end, delivering the highest ENOB in its category, new measurement analysis tools for jitter, noise and serial data links and the outstanding flexibility to support complex analysis in the RF domain. The Tektronix ultra disruptive journey continues!
