Signal Generator Sector: Growth Drivers and Challenges

Growth Drivers

• Expansion of 5G and new advanced communications technologies: The worldwide implementation of 5G and emerging 6G technologies represents a significant increase in demand for signal generators. There is also a big demand for low-latency and reliable networks in telecommunications and IoT. Advanced signal generators are expensive. For instance, high-end VSGs can range from USD 40,000–90,000. As a result, smaller players could struggle to implement advanced test equipment. Companies will need to facilitate the testing of 5G and IoT technologies through the investment in modular, software-defined signal generators that offer robust but cost-effective, scalable solutions.
• Rising demand in aerospace and defense: Aerospace and defense service sectors need signal generators to produce and test radar, satellite communications, and electronic warfare systems. In 2025, at its annual Future State briefing, the US Department of Defense stated that it will spend over USD 4 billion on R&D in electronic testing. This will generate a greater demand for high-frequency RF signal generators. Additionally, the National Institute of Standards and Technology (NIST) cybersecurity framework has mandated and allowed for the secure testing of defense systems. This means that the workplace impediment makes federal agencies force companies to have some aspects of cyber defenses within the components, ie, signal generators.

Technological Trends Reshaping the Global Signal Generator Market

The telecommunications sector is a driving force behind the implementation of advanced signal generators for testing and validating high-frequency signals in their 5G deployments. Manufacturers are utilizing AI-powered signal generators for predictive maintenance and quality control. The healthcare sector is using AI-powered signal generators to improve diagnostics and monitoring. The patterns of adoption vary by sector. Telecom firms are rapidly incorporating signal generators to build 5G infrastructure. Manufacturers are focusing on AI-driven signal generators for automation and efficiency. Healthcare providers are utilizing AI-enhanced signal generators for advanced diagnostics and better care for patients.

Key Technological Trends and Industry Adoption

AI and Machine Learning: Catalysts for Innovation in the Market

Artificial Intelligence (AI) and Machine Learning (ML) are changing the global signal generator market by improving the product development cycle and increasing operational efficiency. For instance, Rohde & Schwarz and NVIDIA successfully delivered an AI/ML-based neural receiver to improve testing efficiencies for 5 G-Advanced and 6G technologies. Anritsu, in collaboration with DeepSig, implemented deep learning using spectrum sensing for easier and faster incorporation of new radio signal models. These developments show how AI and ML will change the whole industry of signal generators through considerable efficiency improvements.

Building Resilient Supply Chains in the Global Signal Generator Market

The global signal generator market is now advancing a supply chain resilience agenda, spurred by global disruptions from geopolitical activity, pandemics, and climate change. Major players in the industry are pursuing digital transformation, supplier diversification, and sustainability as avenues to develop more resilient supply chains. Diversification of sources in the supply chain is another priority. For instance, Rohde & Schwarz has diversified their suppliers in multiple geographies as a strategic alternative to develop supply chain resilience. Diversifying the supply chain also reduces underlying supply shortages due to geopolitical tensions in many areas. Sustainability-focused activities are another area of emphasis for companies in the global signal generator market.

Companies like Anritsu are embedding local suppliers in their supply chain processes as a way to improve turnover time, reduce logistics costs, and reduce their carbon footprint. Collectively, these strategic goals across the global signal generator market aim to further develop the supply chain design of signal generator manufacturers to ensure continued supply, reliability, and continuity of operations for users around the world.

Strategies for Supply Chain Resilience in the Signal Generator Market

Challenges

• Strict data protection regulations: Data protection regulations such as the European Union (EU) General Data Protection Regulation (GDPR) and India's Personal Data Protection Bill (PDPB) impose strict rules about the requirements of signal generators. The compliance requirements have added to the development costs and to the updates to the same product. This has also delayed product launches and limited market access for smaller suppliers. In 2023, Keysight Technologies published its N5182B signal generator as compliant with GDPR in collaboration with telecom regulators in Europe. This effort to gaslight data handling led Keysight to see around 11% improvement in their market penetration.
• Infrastructure readiness gaps in emerging regions: Poor ICT infrastructure in emerging regions around the world, such as Sub-Saharan Africa, slows down the adoption of signal generators. The World Trade Organization reported that over 35% of African countries did not have access to adequate broadband. This restricted testing for 5G and IoT. As a result, the lack of adequate testing creates barriers to market access. In 2024, Rohde & Schwarz piloted portable signal generators in Nigeria and used the pilot to partner with local governments to improve the 5G testing infrastructure. This resulted in the company increasing its market share by over 8% in West Africa.
