Overview

The Cal Test CT4447 Series High-Voltage Differential probes allow conventional earth-grounded
oscilloscopes to be used for floating signal measurements - up to 700 V differential or common mode
voltage (CT4447-1) and up to 1400 V differential or common mode voltage (CT4447-2).
Each model offers user selectable attenuation setting of 10x & 100x (CT4447-1) and 20x & 200x
(CT4447-2), making both probes highly versatile and usable for a broad range of applications including
power supply measurements and moter controls.
Both probes are compatible with any oscilloscope with a 1 MΩ BNC female input and feature up to 30
MHz of bandwidth. The probes can be powered by any oscilloscope USB port, internal batteries (4 AA
batteries included with the probe), or included mains power adapter.
