Caltech CT4432 IsoView15 June 2022 - Cal Test Electronics introduced the CT4432 High-Voltage Oscilloscope Probe. The CT4432 has a 10 kV maximum voltage input rating and is cTUVus listed. The CT4432 High-Voltage Oscilloscope Probe enables the user to safely measure voltage levels up to 10 kV. With the Cal Test Electronics name and certification by cTUVus, the user can be confident this test accessory is both reliable and safe. The CT4432 is covered by a two-year warranty.

The CT4432 High-Voltage Probe features:

  •   Bandwidth of 40 MHz 1
  •   Up to 10 kV input (DC + ACpeak)
  •   cTUVus safety certified
  •   Improved dual-resistor design
  •   Attenuation factor of 1000x
  •   Compensation range of 5 pF - 50 pF
  •   Replaceable tips
  •   Insulated BNC connection
  •   Can be used with your DMM by employing BNC Converter CT3197B
  •   RoHS 2 Compliant
  •   Two-year warranty

Because an oscilloscope has limits to the input voltage it can accept, measuring higher voltages may sometimes require the use of an attenuating high-voltage probe. The CT4432, with an improved dual-resistor design, can accurately and safely step-down higher voltages to an acceptable level. It offers 1000x attenuation and features a compensation range of 5 pF to 50 pF for a wide range of oscilloscope capacitance matching.

This probe is compatible with oscilloscopes (of 1 MΩ input) from all major manufacturers.
