Signal Generators Market Restraints:

• Addressing Cost Barriers to Broader Adoption of Signal Generators Among SMEs

The reason why signal generators find limited applicability among the SMEs is that signal generator offers high value, but initial money pays all due to advanced features. Any general model exceeds USD 10,000, whereas advanced models reach several hundred thousand dollars and find limited usage among smaller-sized manufacturers and research labs. A research states that the cost of signal generators constitutes 15-20% of the total equipment budget for a typical electronics testing lab.

Moreover, the rapid pace of technological advancements makes it difficult for SMEs to invest in equipment that may become outdated within a few years. Although leasing and rental options are available, they do not provide the long-term reliability that ownership ensures. Democratization of signal generator technology by eliminating the cost-related issues to penetrate the market broadly is a necessity.
