Saelig Company，Inc。宣布Saker-MV ISOVP探针的可用性，这是一种新型的电压探头，可通过光纤电缆进行高压隔离测量。光纤隔离提供了高电压安全性和由于没有诱导的外部田间干扰而增加的信号完整性。与常规差分探针相比，这也允许更高的公共模式排斥。可以将探针头放入备用，甚至可以关闭电源，以增加用户安全和电池电量。因此，当不需要测量时，用户无需进入潜在的危险高压区域即可关闭设备。探针头和接收器之间最多可以安装15m的光纤电缆。探针头使用标准1.5V AA电池，LED表示电池状况低。
ISOVP探针的设计最小的输入电容以实现高频测量。典型的模拟光学链路容易出现因连接器不匹配，温度漂移和偏移而引起的较小功率变化。Saker-MV探针使用专有算法来校准链接并消除这些错误。与其他光学设备相比，这提高了总体精度，并节省了设置时间。
ISOVP探针可以执行“热”校准智慧h no input disconnect, making it unnecessary to access the high voltage area during operation. This means saved time and increased user safety. Another useful feature puts the probe system in standby or turns off the probe head from the receiver so that the user does not need access to areas that can be at high voltage during tests. Most high-end oscilloscopes feature proprietary input connectors that force the user to choose the manufacturer’s supplied accessories of the scope, however the ISOVP probe can be used with any 50Ohm terminated oscilloscope. This gives developers freedom to use their digital scope of choice and contain overall investment costs. The probe head features a standard camera tripod mount thread. This makes it more convenient to place the probe inside tightly spaced cabinets or power modules in order to maintain proper clearance distances.
浮动测量已成为IGBT，MOSFET，晶闸管等现代电力电子设备和开关元件设计的重要组成部分。门电压需要测量，现代拓扑通常堆叠这些半导体，以处理更高的电压。差异探针一直是浮动电压测量的主食。但是，它们不是真正的隔离设备，因为它们的带宽是适度的，公共模式排斥受到高频信号和不匹配阻抗的源的限制。它们通常很嘈杂，也不适合测量低压。
