一个合成器,其相位噪声是大是小,ω_n是宽是窄,必须通过测量才能得到正确的反映。在决定ω_n佳时,需要测量相位噪声。在生产过程完了以后,也需要通过测量,才能确定各项技术指标是否达到了原来的要求。本文将讨论相位噪声和环路参数的测量问题。
A synthesizer, the phase noise is large and small, ω_n wide and narrow, must be measured to get the correct response. When deciding ω_n good, you need to measure the phase noise. After the production process is over, we also need to pass the measurement to determine whether the technical indicators have reached the original requirements. This article will discuss the measurement of phase noise and loop parameters.
