CT4432 10 kV High-Voltage Oscilloscope Probe User Manual

Introduction

Overview

The Cal Test CT4432 High-Voltage divider probe can be used with analog or digital oscilloscopes that 

have an input resistance of 1 MΩ (±1%) and nominal input capacitance between 5 and 50 pF. The 

CT4432 is a 1000:1 divider which extends the voltage measurement capability to 7 kV ACrms.

Features of the probe:

•  Up to 10 kV (DC + ACpeak) or 7 kV (ACrms)
•  40 MHz bandwidth (-3dB)
• 

±3% accuracy

•  IEC/EN 61010-031
