Description
Hioki 3276 Clamp Probe for Precise Wideband Current Capture
The Hioki 3276 Clamp On Probe is designed for engineers and researchers requiring highly accurate current measurements across a wide frequency range. Its bandwidth spans from DC to 100 MHz, allowing precise observation of both transient and steady-state currents in applications like switching power supplies, motor controllers, and inverters.
Advanced Wideband Measurement
Equipped with a high-permeability magnetic shield and low insertion loss, the 3276 minimizes measurement derating caused by sensor head heating or nearby high-current lines. The probe’s current transformer (CT) operation enables observation of waveforms with a broad spectrum of frequency components, delivering reliable high-fidelity data for high-speed electronic systems.
High S/N Performance
The probe offers a high signal-to-noise ratio, enabling measurement of low-current waveforms down to 10 mA. Combined with Hioki’s advanced design, this ensures accurate waveform capture without the need for oscilloscope filtering or averaging, providing a clear view of real-time signals.
Ease of Use and Compatibility
The 3276 connects directly to the BNC input terminals of oscilloscopes or Memory HiCorders. For continuous measurements or when instrument power is unavailable, the optional Power Supply 3269/3272 ensures stable operation. Users can handle and connect the probe safely and easily thanks to its ergonomic design and durable construction.
Ideal Applications
This probe is perfect for capturing high-speed transient currents, verifying electronic circuit designs, and monitoring low- to high-current waveforms in advanced research or industrial environments. Its wide frequency response and high accuracy make it an essential tool for modern electronics measurement.
