For instance, in November 2021, Lockheed Martin, a security and aerospace company, and Keysight Technologies Inc. announced a partnership to advance 5G to check the response and security of signal generators to support mission-critical communications for aerospace and defense applications.
- Educating end users on interoperability and the need for specialized testing equipment is essential for market success. At present, the lack of end-user awareness of the need for proactive solutions limits the large-scale use of a signal generator. End-user inability to identify the appropriate answer from various identical systems limits adoption. The COVID-19 pandemic harmed the market, with customers' preferences moving toward essential items, dropping the demand for automobiles and electronics. The aerospace sector also witnessed a significant decline due to the closing of borders and the international travel ban. Thus, vendors supplying these industries reported a decline in revenue in the first quarter of 2020.
Signal Generator Market Trends
Automotive Expected to Hold Significant Share
- The automotive industry is one of the driving forces for the market studied. The growing adoption of electric cars in emerging countries may support market growth over the forecast period. Due to the increased use of electronic components and sensors in vehicles, signal generators have become necessary for testing and troubleshooting sensors, solenoids, actuators, primary and secondary ignitions, and communication data streams. In the Automotive industry, signal generators are generally used to test in-car entertainment and driver assisting aids such as reverse parking sensors and remote keys.
- In recent years, the demand for signal generators has increased due to testing requirements in the R&D of autonomous vehicle technologies and hybrid power-train systems. Global automakers increasingly use signal generators to ensure the safety, quality, and reliability of radars and sensors used in autonomous vehicle technologies. Signal generators test the communication link between critical devices such as radars, sensors, and the central computing unit. Advances in electrical and electronic vehicle technology, which occurred over recent years, made signal generators in testing, troubleshooting, and diagnosis almost mandatory.
- The European Union has also deployed a new regulation, the emergency call (eCall) system, which offers fast assistance in the event of a car accident. Due to the above factor, all new vehicles sold in the European market after the first quarter of 2018 are necessitated to have an In-Vehicle System (IVS) supporting eCall. These systems are required to be appropriately tested before being sold. It is necessary to stimulate the IVS with standard conform GNSS signals in a laboratory to ensure repetitive and standard testing, where a signal generator plays a prominent role.
- Also, to the new eCall regulations, there is a new standard to safeguard GNSS-based devices from the consequences of adjacent band interference. This standard was deployed by the European Telecommunications Standards Institute (ETSI). The standard ensures that any new or altered GNSS product launched in the European Union can withstand adjacent band interference and continue operating without interruption. These systems also need to be tested, generating demand for signal generators.
- The development of autonomous cars has increased the demand for sensors and radar-based systems deployed for safe operation. These sensors and radars are based on an ultrasonic frequency with a spectrum range of around 40 kHz. With the increasing deployment of the in-car entertainment systems and growing investments in R&D, new automotive systems generate the demand for signal generators with frequencies of 50-100 MHz.
