求翻译：(1)用数字技术产生波形信号，分辨率高、稳定性好、频率和相位都可控，输出系统频率不会随工作时间和温度出现漂移。(2)加入了隔离器，防止电磁波能量沿传输线发生的反射，影响信号输出的稳定性，使电路更安全，也起了屏蔽干扰的作用。(3)利用DSP编程实现对频率和相位的控制，可产生多种相位可程控的频率。是什么意思？

(1) generated waveform signal using digital technology, high resolution, good stability, frequency and phase are controlled, the output frequency of the system will not appear with the working time and temperature drift. (2) by adding the isolator to prevent the occurrence of electromagnetic energy
