Product Overview

CT4447-1 is a 30MHz, high voltage differential probe. It is designed to allow earth grounded oscilloscopes to make safe, accurate floating measurement between these two points. The CT4447 series probe convert these floating signals to low-voltage ground referenced signals that can be displayed safely on any ground-referenced oscilloscope. Compatible with oscilloscopes (with 1Mohm input) from all major manufacturers, it can be powered by batteries (included), a universal mains adapter (included), or by the oscilloscope, if USB equipped.
