CT2593-1/CT2593-2 High Voltage Differential Probe 25 MHz / 1400 V (CT2593-1) 25 MHz / 700 V (CT2593-2) Datasheet Overview: Differential probes allow safe, accurate measurment between to voltage points where neither point is referenced to ground. The CT2593 family includes two models: The CT2593-1 and CT2593-2 both offering a 25 MHz bandwidth. Comptable with oscilloscopes from all major manufacturers, the probes can be battery operated, powered by a universal adapter (optional), or powered by USB power lead (optional) if the oscilloscope is so equipped. Features: Technical data subject to change. (c) Cal Test Electronics 2017. 25 MHz bandwidth Up to 1.4 kV differential and common mode voltage for the CT2593-1. Up to 700 V for CT2593-2.
