Signal Generator MarketSize and Trends

A signal generator is an electronic device, which generates signals that are used for testing, designing, and troubleshooting electronic device. Signal generator produces repeating or non-repeating signals in both, digital or analog formats. Signal generator can provide ‘ideal’ waveforms or it may add known, repeatable amounts, and types of distortion (or errors) to the signal it delivers. Signal generators have different applications in the electronics sector such as measurement verification, characterization, and stress/margin testing. Function and arbitrary waveform generator are the most popular and have high demand in signal generators, across industries. With the advent of computers, flexible, software-enabled, and programmable signal generators have replaced conventional signal generators that were embedded in hardware units.

Signal Generators’ Ability to Provide Stable Wireless Signals for Telecommunication Applications is Driving Growth of the Market

Signal generator are used by various industries such as telecommunication, aerospace and defense, and automotive. Increasing demand for signal generators in telecommunication industry is one of the key factor driving growth of the market of signal generators. This is owing to the fact that signal generators provide high signal purity, create low noise, and give frequency stability in wireless communication networks. Wireless technology has been greatly influenced by signal generators due to the advent of cellular technologies such as 2G, 3G, and 4G that use signal generators for generating signals. Furthermore, signal generators are also used in other mobile technologies such as Code Division Multiple Access (CDMA), Global System for Mobile communications (GSM), Long Term Evolution (LTE), and Wideband Code Division Multiple Access (WCDMA) that is tested using ‘real-world’ signals. Increase in budgetary allocations of aerospace and defense industry also acts as one of the major growth drivers of the market of signal generators. This is due to use of signal generators in applications such as Radio Frequency & Intermediate Frequency (RF/IF) signal generation and Low Order (LO) substitution, which helps in achieving greater precision in avionic instruments. For instance, according to a 2018 report by Invest India (National Investment Promotion and Facilitation Agency) in India, the financial allocation for defense in budget of 2017-18 was nearly US$ 41 billion with US$ 13.3 billion allocated for capital expenditure. This was equivalent to 31.7 percent of the total budgetary allocation for all sectors put together.

Growing automotive industry is also one of the major growth drivers of the signal generators market. This is owing to the fact that signal generators are used for functional testing and optimization of engine control units (ECU) for automotive applications by simulating various automotive sensor signals such as pressure, temperature, speed, rotation, and angular position. For instance, according to a 2017 report by, India Brand Equity Foundation (IBEF), the Indian automotive industry (including component manufacturing) is expected to reach US$ 251.4-282.8 billion by 2026. Furthermore, signal generators are used in automotive applications to simulate crankshaft, camshaft, wheel, knock, and to check the working of automotive sensors such as position sensors, image sensors, and parking assist sensors, which are used in all modern day automobiles.
