30 MHz High-Voltage Differential Probes

Caltest CT444705 August 2022 - Cal Test Electronics introduced the CT4447 Series of 30 MHz High-Voltage Differential Probes. Two different attenuation settings are offered, covering the most requested voltage ranges. Compatible with oscilloscopes (with 1 MΩ input) from all major manufacturers, the probes can be powered by batteries (included), a universal mains adapter (included), or by the oscilloscope, if USB equipped.

Oscilloscope users are often faced with the need to make measurements between two voltages, both of which are not at earth ground. Differential probes are designed to allow earth grounded oscilloscopes to make safe, accurate floating measurement between these two points. The CT4447 Series probes convert these floating signals to low-voltage ground-referenced signals that can be displayed safely on any ground-referenced oscilloscope.

The model CT4447-1 offers an attenuation 10x/100x and a maximum differential Voltage of 700 V. The model CT4447-w offers an attenuation 20x/200x and a maximum differential Voltage of 1.4 kV.

The CT4447 Series features:

  •   Bandwidths to 30 MHz
  •   Up to 1,400 V differential (DC + pk AC)
  •   1,000 V CAT III rated
  •   cTUVus safety certified
  •   Voltage over range indicator
  •   Switchable attenuation ranges
  •   Multiple power options - batteries, oscilloscope, or mains
  •   Insulated BNC interface
  •   Protective rubber boot

The probes are covered by Cal Test's two-year warranty.
