Measuring intermodulation distortion is critical for the telecommunications industry. Two-tone IP3 testing is fine for many applications, but does not do a very good job of simulating actual channel conditions on a multi-carrier system, which more closely resembles bandwidth-limited white noise.
Instead, use our BB60C RF spectrum analyzer and VSG25A vector signal generator for cost-effective Noise Power Ratio (NPR) testing to accurately characterize multi-carrier intermodulation performance.
This application note offers an explanation of NPR testing and walks you through the process of performing a test using our devices.
