Testing RF devices, like power amplifiers, requires a certain input power at the device under test (DUT). Sometimes, more power than a signal generator can deliver is needed. This may be the case when devices require higher input power, or when they need to be connected using long cables, which introduce large insertion losses at high frequencies. In these cases, an external amplifier can be used to deliver the required power to a DUT.This application note gives a guideline how to increase the power delivered to a DUT by an R&S®SMW200A vector signal generator using an external amplifier.It covers shifting the power reference plane from the generator output to the DUT input using an R&S®NRP power sensor and mitigating linear and nonlinear distortions using an R&S®FSW signal and spectrum analyzer.

汽车雷达对于防碰撞和自适应巡航控制等安全系统至关重要。雷达是 ADAS/AD 系统和传感器融合过程的重要组件。汽车雷达传感器的有效全向辐射功率 (EIRP) 是从雷达天线发射的总功率，也是衡量信号强度和覆盖能力的综合性指标，对于评估汽车雷达传感器的性能非常重要。AREG800A 汽车雷达回波发生器能够在验证汽车雷达传感器的时候轻松测量 EIRP。

This application note addresses the diverse possibilities of interoperability between Rohde & Schwarz power sensors and Rohde & Schwarz signal generators. All current and many legacy Rohde & Schwarz signal generators offer the capability of directly connecting power sensors. This enables power measurements without the need of a base unit or separate PC to display the readings. Furthermore, sensors can be used for special tasks like filling a user correction table or continuously controlling levels at crucial points in the measurement configuration.
