Description
Overview
The Cal Test Electronics CT3681 is a high-voltage differential probe designed for safe, accurate measurements between two voltage points where neither is referenced to ground. With attenuation settings of 100x/1000x, a 70 MHz bandwidth, and support for differential voltages up to ±7,000V, the probe provides precision measurements in demanding test environments. It is compatible with oscilloscopes from all major manufacturers that have 1 Megohm input impedance and can operate on battery or external power.
