CT6701 Current Probe

CT6701 Current Probe

Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes. The CT6701 is a high-sensitivity current probe that offers a wide DC to 120 MHz bandwidth and 5A of continuous input, and is ideal for capturing transient current signals from switching power supplies, inverters, and motor controllers.

Key Features

  • Wide band: [CT6700] DC to 50 MHz (-3 dB), [CT6701] DC to 120 MHz (-3 dB)
  • High S/N characteristic ideal for ultra low 1 mA order current waveforms
  • Connect directly to an oscilloscope’s BNC input terminal *1

*1 Connecting the device’s metal BNC terminal to a Memory HiCorder’s plastic BNC terminal may damage the plastic terminal or cause it to become misshapen.
