本文讨论信道化、时间积累的频谱分析器的工作原理和优点.然后介绍一种采用布雷格小盒的系统,概括说明它在低电平连续波信号下的性能.还讨论了短时积累用于强连续波信号和脉冲信号的问题.
This article discusses the principle and advantages of spectrum analyzer with channelization and time accumulation.And then introduces a system using a Bragg cell to summarize its performance under low level continuous wave signal.It also discusses the short time accumulation Yu Qiang continuous wave signal and pulse signal problems.
