Wideband Current Probe for Oscilloscopes
Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes. The 3274 supports wide DC to 10 MHz bandwidth signals and 150 A of continuous high input, letting you capture transient current signals from switching power supplies, inverters, and motor controllers. The probe is designed with a high permeability magnetic shield to reduce the effects of electric fields, making it ideal for measuring low currents or nearby high-current lines.
Use with an instrument with a high input impedance of 1 MΩ or higher.
Key Features
- Waveform observation across a wide band from DC to MHz
- Connects directly to oscilloscope or Memory HiCorder BNC input terminal (*1)
