10× the Sensitivity of Conventional Probes Deliver Precise Measurement of Low Current Waveforms from 1 mA

SKU: CT6700 Category:

Model No. (Order Code)

CT6700 From 1mA, 50MHz bandwidth

Note: Use optional Power Supply 3269 or 3272 to drive the current probe when power from the Memory HiCorder or oscilloscope is not available. Exercise care concerning offset drift when performing continuous measurement over extended periods of time.

Good Design



Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes. The CT6700 is a high-sensitivity current probe that offers a wide DC to 50 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.
