Panlab 特有的条件恐惧和震惊反射联合测试系统将震惊实验（包括前脉冲抑制实验）和条件恐惧实验放到一个实验箱体中完成，搭配不同的配件，即可执行震惊或条件恐惧测试，这样的设计不仅节约了用户宝贵的实验空间，也大大的节约了采购成本。 

实验箱体采用独特的重力传感器来监测动物的行为，具有很高的灵敏度，可准备地觉察到动物的微小动作，即使小鼠的轻微动作也可识别，从而判断动物的活动/僵立（Freezing）以及震惊反应，动物的任何反应经过特有的放大器后传输到计算机，使用统一设计的PACKWIN软件对数据进行实时的采集和分析，PACKWIN 软件可以灵活搭配 STARTLE和 FREEZING 实验模块，分别应用于震惊和条件恐惧实验。同时，系统还可以搭配多种硬件刺激模块，包括灯光、声音、电刺激、吹气，这些硬件均可以通过软件编程进行控制。 

系统可适用于不同体重大小的小鼠和大鼠（15-500g），同时在条件恐惧实验中，可搭配不同的环境组件，对墙壁和地板的材质、颜色进行更改，也可以将动物活动的空间变为圆筒等形状。
