Keysight Launches Wireless Coexistence Test Solution to Accelerate Compliance and Innovation

Key Terms

RF technical

rf (commonly written r_f) denotes the risk-free rate — the theoretical return on an investment with no chance of loss, often used as a baseline for valuing other assets. Investors use it like a yardstick: returns above this number compensate for extra risk, so it helps price stocks, bonds and option valuations and guides decisions about whether higher-return opportunities justify their added risk. Think of it as the safe deposit box interest rate against which riskier bets are measured.

ANSI C63.27 regulatory

ANSI C63.27 is a U.S. technical standard that describes how to test a wireless device’s ability to operate reliably when other wireless signals are nearby — in other words, how well it “coexists” in crowded radio environments. For investors, compliance signals lower risk that a product will suffer performance problems, face regulatory hurdles, or need costly redesigns; think of it like testing whether someone can hold a conversation at a noisy party without losing key details.

vector signal generator technical

A vector signal generator is a laboratory instrument that creates precise, programmable radio-frequency signals with controlled amplitude, frequency and phase so engineers can mimic real-world wireless transmissions. For investors, it matters because this tool is essential for developing and testing wireless chips, antennas and communication systems—faster, more accurate testing helps firms bring reliable products to market sooner and reduces the risk of costly design problems later.

modulation bandwidths technical

Modulation bandwidths are the range of signal speeds and frequencies a communication or sensor device can use to change (modulate) its output without losing quality, like how wide a water pipe must be to allow faster or more variable flow. For investors, wider modulation bandwidths usually mean a product can carry more data, support faster performance and new applications, and stay competitive—affecting sales potential, market share and technology risk.

packet rate error (PER) technical

Packet rate error (PER) measures the share of digital data packets that fail to arrive intact over a network, usually expressed as a percentage of total packets sent. It matters to investors because a high PER is like a mail service where many letters arrive damaged or missing: it degrades product or service performance, raises support and infrastructure costs, and can harm customer satisfaction and revenue for companies that rely on reliable data transmission.

Smart, scalable, platform helps engineers reduce regulatory risk and validate wireless device performance faster in crowded RF environments

SANTA ROSA, Calif.--(BUSINESS WIRE)-- Keysight Technologies, Inc. (NYSE: KEYS) today announced the release of its new Wireless Coexistence Test Solution, an automated, and standards-aligned platform designed to help engineers quickly and repeatably validate wireless device performance in increasingly crowded RF environments.

As wireless devices proliferate across healthcare, consumer, and industrial applications, engineers face growing pressure to demonstrate reliable operation in the presence of interference — both to meet regulatory expectations and to ensure real-world performance. Keysight’s new solution addresses this challenge by automating wireless coexistence testing, reducing manual setup, improving repeatability, and enabling earlier risk identification during development.

In regulated markets such as medical devices, wireless reliability is directly tied to patient safety and regulatory approval. The U.S. Food and Drug Administration recommends manufacturers assess wireless coexistence risk, with guidelines pointing to ANSI C63.27 as a recognized framework for evaluation. However, executing these tests manually is time-consuming, complex, and difficult to reproduce. Keysight’s Wireless Coexistence Test Solution automates pre-compliance testing aligned with ANSI C63.27, helping teams identify interference risks earlier, reduce rework, and better prepare for regulatory submissions.

The Wireless Coexistence Test Solution includes a built‑in library of close to one hundred predefined test scenarios aligned with ANSI C63.27, enabling engineers to efficiently execute all three tiers, from baseline interference to complex multi‑signal environments, without building custom test setups from scratch. To replicate real-world RF conditions, the solution integrates a wideband vector signal generator covering 9 kHz to 8.5 GHz, scalable to 110 GHz, with modulation bandwidths up to 250 MHz (expandable to 2.5 GHz), and one RF port supporting up to eight virtual signals.

Built on OpenTAP, an open-source cross-platform test sequencer, the solution offers scalable, configurable testing through a user‑friendly GUI and open architecture, allowing engineers to upload custom waveforms and validate test plans offline in simulation mode. The solution streamlines the entire test flow with sequenced automation, reducing test cycle time by over 50 percent and shifting focus from setup tasks to device-under-test (DUT) behavior analysis. Together, these capabilities ensure engineers can accelerate R&D development, achieve compliance, and deliver safer, more reliable wireless devices.

In addition to the test platform, Keysight offers consulting expertise to help teams define, track, and measure key performance indicators such as latency, throughput, jitter, and packet rate error (PER) — tailored to specific devices and operational use cases.

Han Sing Lim, Vice President and General Manager of Keysight’s General Electronic Measurement Division, said: “Wireless coexistence testing is no longer optional — it’s essential for ensuring product safety, performance, and regulatory readiness. With our new Wireless Coexistence Test Solution, engineers can automate ANSI C63.27-aligned testing, shorten development cycles, and gain earlier insight into how their devices perform in real-world RF environments. It’s a smarter, faster path for R&D, enabling iterative testing across real‑world use cases and scenarios.”
