The global function generator market size stood at USD 1.59 billion in 2019 and is projected to reach USD 3.31 billion by 2032, exhibiting a CAGR of 6.64% during the forecast period.

A function generator is a type of signal generator generating waveforms with common shapes such as sine waves, square waves, and triangular waves. Furthermore, these generators also help to vary the waveforms' characteristics, changing the pulse length and the ramps of the different edges of the triangular waveforms. Apart from generating the waveforms, this type of generator can also add a DC offset to the signal.

Unavailability of Financial Assistance to Industries amid  COVID-19 to Affect Market Growth

Unprecedented problems created by the COVID-19 pandemic have affected industrial operations worldwide. Different nations have introduced several combat measures such as social distancing rules and shutdown of various manufacturing & processing facilities. For instance, the sudden slump in global crude oil prices has led the international crude oil value to go negative in April 2020 for the first time in the history of the oil industry. It also has halted the rampant exploitation of any new reserves, barring the development of onshore and offshore structures, which has stabilized the deployment function generators. On the other hand, the halt of operations in capital-intensive industries such as electronics, automotive, aerospace, and oil & gas has led to a deficit in investments in new projects, impacting the manufacturing of these generators.

Growing Adoption of AI and Wireless Communications in Aerospace & Energy Sectors to Fuel Market Expansion

Wireless communications, artificial intelligence (AI), and automation are gaining wide popularity in the aerospace and energy sectors. Wireless communication systems have been equipped with satellite communication phones, mobile phones, broadband, and other internet facilities. These systems have electronic components such as band-pass filters, mic, and network scanners for active operations. Function generators are used to test these components' reliability and operational flexibility by simulating real-time operations in laboratory conditions. According to UBS Group AG, the artificial intelligence industry was valued at approximately USD 40 billion and is expected to grow at a 40% CAGR during 2020-2027. Progress in artificial neural networks has also driven the adoption of AI in various industries such as aerospace, healthcare, manufacturing, and automotive.


Rapidly Increasing Energy Demand Worldwide to Propel Product Demand

Function generators are widely used in the energy sector for testing electronic components of several devices such as solar photovoltaic (PV) inverters, electronically-assisted drilling, and metering devices. The exponential rise in power demand, primarily across emerging economies, coupled with the development of new-generation distribution and transmission networks, will favor the demand for these generators market. Additionally, optimistic targets to deploy green energy technologies such as hydro, wind, and solar are likely to propel their adoption further. For instance, in September 2020, the U.S. Energy Information Administration (EIA) forecasted that the global energy consumption would rise by  50% by 2050, with the total intake in residential and commercial buildings rising from 91 quadrillion British thermal units (Btu) to 139 quadrillions Btu, reflecting an increase of approximately 65%.

Rising Demand from Aerospace Sector to Drive the Market

The demand for military equipment is on the rise as governments across the globe are constantly focusing on modernizing their defense capabilities in response to the rising security concerns. The uncertainties and the persistent complexities of the international security environment are anticipated to drive up global defense spending during the forecast period. For example, according to the Stockholm International Peace Research Institute (SIPRI), in 2019, total global military spending reached USD 1,917 billion, representing the largest annual growth since 2010 and an increase of 3.6% from 2018 levels. The biggest spenders, as per SIPRI data, were the US, China, India, Russia, and Saudi Arabia. This spike in spending indicates modernization and sophistication of military technologies across countries, which is primarily reflected by the electrification of weapon and communication systems. Function generators are used in the testing of satellite and navigation systems and also play a critical role in strengthening existing defense equipment as these devices provide efficient testing and repairing services to electronic weapon systems.


High Cost of Function Generators May Obstruct Market Growth

A  function generator is a low-frequency electronic testing device that is primarily used in academic laboratories for research and development purposes. However, these generators require an oscilloscope, fixed and variable power supply, breadboard, and USB port. The cost of each device is high, and these generators also require more space. This factor is likely to hamper the function generator market growth.


By Product Type Analysis

Analog Type Generator to Hold Significant Share Backed by  Efficient Designs and Better Load Bearing Capacities

Based on type, the global market is segmented into analog and digital. The analog type segment is projected to lead the market during the forecast period due to the simpler construction and low costs of analog generators.
