最真实的信号呈现

最真实的信号呈现


SigOFIT光隔离探头具有极高的共模抑制比，在200MHz时CMRR高达122dB、在1GHz时CMRR仍然高达108dB，是判定其他电压探头所测信号真实性的终极裁判。

极高的测试精度与稳定性

极高的测试精度与稳定性


作为判定其他电压探头所测信号真实性的终极裁判，测试精度是SigOFIT光隔离探头的重要指标。SigOFIT光隔离探头，具有极佳的幅频特性，直流增益精度优于1%，底噪小于1.46mVrms，预热后零点漂移小于500μV。

第三代半导体的最佳测试手段

第三代半导体的最佳测试手段


第三代半导体器件由于导通与关断时间很短，信号具有更快的上升沿和下降沿，信号中具有很高能量的高频谐波，SigOFIT光隔离探头在最高带宽时，仍然具有超100dB的共模抑制比，可以近乎完美地抑制高频共模噪声所产生的震荡，所呈现的信号没有额外多余成分，是第三代半导体测试的不二之选。

测试氮化镓（GaN）不炸管

测试氮化镓（GaN）不炸管


SigOFIT光隔离探头测试引线短且采用同轴传输，探头输入电容低至2.6pF，测试氮化镓（GaN）十分安全。

使用灵活，高效便捷

使用灵活，高效便捷


SigOFIT光隔离探头比传统高压差分探头体积更小，探头引线更精巧，使用更加灵活方便；探头响应快，上电即测，校准时间小于1秒，可实时保证精确的信号输出。

测试量程更宽

测试量程更宽


不同于高压差分探头只可以测试高压信号，SigOFIT光隔离探头通过匹配不同的衰减器，可以测试±1.25V至±5000V的差模信号，并实现满量程输出，达到很高的信噪比。
