技术问答

N2790A是KEYSIGHT公司推出的一款100MHz探头带宽可提供用户选择的50:1或500:1衰减比的高电压差分探头，最大差分电压测量范围(直流+交流峰值)在500:1分压比下高达±1400V，50:1的分压比也能达到±140V。该款差分探头的最大共模工作电压达±1000V(CATII)或±600V(CATIII)，增益的精度在20°C~30°C环境温度下控制在±2%读数，0~20°C、30~50°C温度范围内控制在±4%读数，适合应用于当今的高电压信号变化测量、车载总线测量和数字系统设计，提供安全和精确的浮置差分信号测量功能。N2790A标配的附件包括2个点测探针、2个伸缩式挂钩探针、两个鳄鱼夹、4种颜色的ID标签、直流偏置调节工具以及操作手册，探头坚固紧凑的探针很方便用于在狭窄空间内对小尺寸的元器件进行精确的测量。

N2790A高电压差分探头测量响应的上升时间小于3.5ns，展现了超快速探测的灵敏性能，其测量的最大无损电压在差模状态为±1500V(直流+交流峰值)，共模状态为±1300V，输出的电压摆幅在±2.8V(1MΩ, 500:1)，探针两端的输入电阻分别为4MΩ（每个探针接地输入）和8MΩ（探针输入端之间），其输入寄生电容可分别低至7pF和3.5pF，因此能够极大程度降低电路的负载。N2790A差分探头还有较高的共模抑制比(CMRR)能力，500V直流探测时抑制比为-70dB，交流信号测量时在50/60Hz高达-80dB，1kHz、1MHz的抑制能力也高达-50dB，因此探针具有的波动电压抑制力，同时探针的输入基准噪声<300mVrms(500:1)或<50mVrms(50:1)，输入噪声能够降到最低使得探头能在不同应用环境下均能得到精确的测量结果。因此，该款高电压差分探头在消费、工业等电子领域均可展现出卓越的探测性能。

图1 N2790A型号100 MHz高电压差分探头及标配附件示意图

N2790A差分探头的过量程指示器可在探头输入超过探头动态范围时向用户发出警告，内部采用的AutoProbe接口能识别所接探头的类型，并按需要正确设置输入阻抗、衰减比、探头电源和偏置范围。N2790A差分探头的正常工作环境温度为-10°C~50°C，适应正常的应用环境温度，同时探头具有良好的Vout/Vin频率响应特性和Ω频率响应，并具有良好的拟合效果，展现了高电压差分探针的探测平稳性，有利于提升示波器探测系统的探测信号的精度。

· 探针两端的输入电阻分别为4MΩ（每个探针接地输入）和8MΩ（探针输入端之间），其输入寄生电容可分别低至7pF和3.5pF，能极大程度降低电路的负载；

· 具有较高的共模抑制比(CMRR)能力，500V直流探测时抑制比为-70dB，交流信号测量时在50/60Hz高达-80dB，1kHz、1MHz的抑制能力也高达-50dB；

· 输入基准噪声<300mVrms(500:1)或<50mVrms(50:1)，输入噪声能够降到最低，在不同应用环境下均可得到精确的测量结果；

· 差分探头检测适用于消费电子、车载电子和工业设备等领域的测量应用；

· 采用的AutoProbe接口能识别所接探头的类型，并按需要正确设置输入阻抗、衰减比、探头电源和偏置范围。

N2790A高电压差分探头的典型应用：

· 高电压信号变化测量

· 车载总线的差分信号测量

· 数字系统设计的通用差分信号测量

用示波器进行开关电源测量时，浮地测量8个实用的小技巧

很多初级工程师在用多个探头进行电源测量时，刚开机电源产品就“炸机”，甚至示波器也发生损坏。电源测试中大多数电压测试是浮地测量，需要用差分探头测试。这是因为示波器探头之间是共地的，在同时测量电源原边和副边的时候，如果用一根探头接原边的地，另一根探头接副边的地，相当于把电源的原边和副边的地短路在一起，这样短路后的大电流就会烧坏电源产品和探头，甚至是损坏示波器。
