The margins for error shrink as wireless systems push into higher frequencies.
As wireless systems climb into the millimeter-wave spectrum, the margin between breakthrough and costly failure narrows to a hair's breadth — and it is in that narrow margin that companies like Keysight Technologies make their case. At IMS 2021, gathering first in Atlanta and then in virtual space through late June, Keysight is presenting a suite of tools meant to guide engineers through the compounding complexities of 5G, satellite, and automotive radar development. The company's presence reflects a broader truth about technological progress: the instruments we use to measure the world shape the world we are able to build.
- Higher frequencies are exposing the limits of traditional testing, and a single miscalibration can erase months of engineering work.
- Keysight is claiming a 100x speed advantage in frequency converter testing — a bold assertion in an industry where development timelines are already under pressure.
- A handheld 5G field-test tool addresses the unglamorous but critical reality of engineers troubleshooting live networks from rooftops and cell sites.
- Workshops on sub-terahertz testbeds and 6G signal analysis signal that the competitive race to define next-generation wireless standards is already underway.
- Keysight's layered sponsorships and a keynote session titled 'from DC to Daylight' position the company not merely as a vendor, but as a shaping force in the industry's future direction.
Keysight Technologies is arriving at IMS 2021 with a full portfolio of millimeter-wave testing solutions, setting up in Atlanta in early June before moving to virtual workshops later that month. The company is targeting the fundamental tension at the heart of next-generation wireless development: as 5G networks, satellite systems, and automotive radar push into higher frequencies, the tolerance for error collapses, and the tools engineers rely on must evolve accordingly.
On the Atlanta show floor, Keysight will demonstrate six solution areas spanning the entire development arc — from modulated signal simulation and amplifier stability analysis to phased-array radar design and high-frequency circuit co-simulation. Among the headline capabilities is a frequency converter testing approach the company claims runs 100 times faster than conventional methods, a meaningful advantage given how central these components are to satellite and 5G infrastructure. A handheld field-test tool for 5G beamforming verification speaks to the practical demands of engineers working in the field, while a 110 GHz two-channel real-time oscilloscope targets researchers already looking beyond current standards.
The virtual workshops running June 20 to 25 broaden the conversation considerably, with sessions on 6G research, sub-terahertz testbeds, and electronic warfare signal analysis — a reminder that military applications continue to drive much of the innovation in high-frequency measurement. Keysight's June 23 presentation, 'Test Validation in the 6G Era: from DC to Daylight,' frames measurement itself as a strategic discipline, not merely a technical one. For a company with $4.2 billion in annual revenue, IMS is both a product showcase and a declaration of intent about who will help define the next era of wireless technology.
Keysight Technologies is bringing a full arsenal of millimeter-wave testing equipment to IMS 2021, the annual conference where the wireless industry gathers to solve its hardest measurement problems. The company will set up shop in Atlanta in early June, then pivot to virtual workshops later that month, showcasing tools designed to handle the peculiar challenges that come with building 5G networks, satellite systems, and automotive radar—all of which operate at frequencies where traditional testing approaches break down.
The core problem Keysight is addressing is straightforward but severe: as wireless systems push into higher frequencies, the margins for error shrink. Engineers designing these systems face tight timelines, complex signal modulation, and standards that demand precision measurement. A small mistake in simulation or a misread on a test instrument can waste months of development work. Keysight's pitch is that its solutions—from design simulation through field validation—eliminate guesswork and compress the testing cycle.
On the show floor in Atlanta from June 8 to 9, Keysight will demonstrate six major solution areas. The 5G mmWave Design Flow covers the full arc from modulated signal simulation through amplifier stability analysis and electromagnetic circuit co-simulation, with new data analysis tools that let engineers extract deeper insights from high-frequency circuit behavior. A separate Radar System Design Flow tackles active electronically scanned array design, the kind of phased-array radar that guides missiles and autonomous vehicles. The company is also highlighting the N9042B UXA X-Series signal analyzer, a piece of equipment built to measure the kinds of distortions and phase noise that plague millimeter-wave signals.
One of the more striking claims involves frequency converter testing. Keysight says its approach is 100 times faster than the traditional spectrum analyzer method, a claim that matters because frequency converters are essential components in satellite and 5G infrastructure. The company is also rolling out a handheld field-test solution for 5G coverage and beamforming verification—the kind of tool that field engineers need when they're standing on a rooftop trying to figure out why a network isn't performing as designed. For the most demanding applications, Keysight will showcase a 110 GHz, two-channel real-time oscilloscope capable of instantaneous bandwidth and RF measurements, aimed at researchers developing the next generation of wireless technology.
The virtual portion of the conference, running June 20 to 25, expands the scope considerably. Keysight is offering workshops on low-noise measurement, 5G new radio signal analysis, and the emerging frontier of 6G research. One workshop focuses on sub-terahertz testbeds for 6G development—a signal that the company is positioning itself not just as a vendor solving today's problems but as a player in the race to define tomorrow's wireless standards. There's also a dedicated session on advanced electronic warfare signal analysis, reflecting the reality that military and defense applications drive much of the innovation in high-frequency measurement.
Keysight's role at the conference extends beyond booth demonstrations. The company is a Silver Sponsor of IMS itself, a Corporate Sponsor of the Connected Future Summit, and a Gold Sponsor of the Automatic Radio Frequency Techniques Group. On June 23, Keysight will present a session titled "Test Validation in the 6G Era: from DC to Daylight," signaling that the company sees measurement and validation as central to the next wave of wireless innovation. For a company that generated $4.2 billion in revenue in fiscal 2020, IMS represents both a showcase for current capabilities and a statement about where the wireless industry is headed.

The Hearth Conversation Another angle on the story
Why does millimeter-wave testing matter so much that a company like Keysight devotes this much attention to it?
Because the frequencies are so high that traditional measurement approaches stop working. You can't just use a spectrum analyzer and call it done. The signals are fragile, the margins are tight, and if you get the measurement wrong, you've wasted months of design work.
What's the practical difference between testing at, say, 5 GHz versus 110 GHz?
At higher frequencies, everything becomes more sensitive. Phase noise, distortion, tiny impedance mismatches—they all matter more. And the equipment itself has to be more sophisticated. A 110 GHz oscilloscope is a fundamentally different animal than a conventional one.
The claim about 100x faster frequency converter testing—is that a real engineering win or marketing language?
It's real. If you can compress a test cycle from hours to minutes, that compounds across hundreds of devices. In manufacturing, that's the difference between a product being profitable and not.
Why is 6G research showing up at a 2021 conference about 5G?
Because the wireless industry doesn't wait for one standard to mature before planning the next. The companies that define 6G will be the ones who start thinking about measurement and validation now. Keysight is positioning itself as essential to that process.
What does a handheld field-test tool actually tell you that you can't get from a lab?
Whether the network works in the real world. A lab is controlled. A rooftop in Atlanta in June is not. You need to verify coverage, beamforming, signal quality—all the things that matter to actual users.
Is Keysight betting that measurement will be as important to 6G as it was to 5G?
More important, probably. As frequencies go higher and systems get more complex, the ability to measure accurately becomes a competitive advantage. It's not just about selling instruments. It's about being the company that helps define what "correct" means.
