频率范围可达DC-400MHz，内置6GHz Channel 3
每秒12位的精确测量40ps时间间隔分辨率
绝佳的万用特色
完整的数学运算功能及简易的操作面板
快速测量及特殊应用
免费的远端操控软件及常用的SCPI指令
注意 : 红色字体为U6220A 没有提供的功能
12位分辨率 含6GHz频率测量
本公司根据ISO9004制程所生产出的U6200A通用频率计数器能够提供每秒12位数频率分辨率(见Figure-1)、40 ps时间间隔解析，以及完整的测试与分析功能。另外，本产品还内建第三频道，可量测频率从375 MHz到6GHz，而第一和第二频道，可量测频率从1 mHz到 to 400 MHz。
绝佳的万用特色
本产品U6200A也提供了其它不错的功能及设计，例如：频率比率(每秒11位)、时间间隔、周期(2.5 ns至1000 s)、 工作周期、脉冲宽度、上升/下降时间、峰值电压( 100 Hz到300 MHz)、相位、总计、时基温度变化稳定度(小于1 PPM)、老化率(每年小于2 PPM)、时基参考(I/O见Figure-2)、前端完全隔离。另外还提供20组设定存储空间，让使用者储存常用的设定(见Figure-3)。
完整的数学运算功能及简易的操作面板
本产品U6200A内建统计及数学运算功能。使用者可以做一般量测、同步量测、中间值统计、最大/最小值统计、三角函数统计及标准差统计(见Figure-4)。以及运用Scale & Offset功能按键，使用者可依实际应用加入补偿值。而要完成以上操作并根据需求输入数值，使用者只需轻易地利用本产品面板上的数字键即可。再者，本公司为了使用者操作方便，将功能按键设计成当功能启用时，按键便会亮起(见Figure-5)。
快速测量及特殊应用
本产品U6200A采用即时数字信号进程技术，即可在分析数据之际，同时读取新值并做快速测量。值得一提的是「限值模式」，使用者可以依需求设定最大及最小值，并通过面板设定成Go-On或Stop，再开启USB Output，此时只要测量值超过所设定的范围， U6200A就会按照设定继续或停止测量，同时输出信号触发外部装置(见Figure-6)。
免费的远端操控软件及常用的SCPI指令
使用者除了可以通过微软Excel应用软件(见图九)，经由内建的USB或选购的GPIB接口取得资料，还可以利用U6200A支持网路伺服器功能，将内建的网络通信接口连结PC ，并在PC上的浏览器中输入预设的位址192.168.0.247，使用者便可通过网络操作界面GUI(见Figure 10)操控U6200A。另外，靠着与安捷伦53132A相容的SCPI指令集，U6200A能够在应用上提供使用者熟悉的语法字串。相关指令集信息，请参照使用U6200A使用手册第七章节。

该图不包括触发错误的影响。 为了给这个误差项的附加效应设置一个上限，有必要从正确的图表中确定频率误差并添加一个触发误差项，如下等式：
外部源和输入放大器噪声可能会提前或推迟定义测量开始和结束的触发点。 由此产生的时序不确定性是信号压摆率和寄生噪声尖峰幅度（相对于输入迟滞带）的函数。
