Description
The 4231 is designed to safely analyze floating signals. The built in amplifier scales and converts the high voltage differential input to a low, voltage single-ended BNC output, compatible with any oscilloscope. The inputs are useful in measurements of power semiconductor circuits, robotic drives, NC machines and the latest switching circuits.
