RF and microwave ICs are widely used in electronic test and measurement instruments, such as spectrum analyzers, network analyzers, signal generators, and communication testers. As wireless communications become more and more popular in our lives, such as 4G/5G and the Internet of Things, the requirements for their test benches are also increasing. In this article "RF and Microwave Solutions for Electronic Test and Measurement" by ADI, we will focus on how ADI products are integrated into the relevant signal chain!

Key Challenges and System Design Considerations

Wide dynamic range

Minimizing the noise floor (e.g., phase noise) of an RF test bench is important for maintaining test signal purity over a wide dynamic range. However, obtaining a clean signal is a challenge as more digital signal processing tasks increase radiated noise.

Wide bandwidth

Another important goal is to maximize the bandwidth of the RF test bench. Software-defined radio can be implemented in this platform to facilitate configuration, operation, maintenance, and upgrades. However, finding components good enough to cover this wide bandwidth is a challenge.

stability

Time drift and temperature drift are two key factors in obtaining accurate, repeatable readings over the operating range from electronic test and measurement instruments . However, neither factor is easy to calibrate out.
