scanning line frequency

基本解释

The EB scanning track, scanning frequency and energy density distribution at heating zone could be programmed off-line and adjusted on-line.
利用该系统可对电子束扫描轨迹、扫描频率以及加热区域电子束能量密度的分配进行离线编辑和在线调节。
The clock transition frequency and linewidth of the clock transition line were obtained by scanning the microwave frequency in a narrow region.
通过减小微波扫描的频率范围，得到钟跃迁频率和谱线线宽。
In the new design, several fixed test points on a transmission line are chosen instead of previously frequency scanning. We have composed an automatic test system.
在测试过程中，本文提出了一种天线阻抗的传输线多点测量法，并由此实现了一种自动测试系统。
