Description
Hioki wide frequency current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes CLAMP ON PROBE 3276
The 3276 offers a wide DC to 100 MHz bandwidth and 30A of continuous input, and is ideal for capturing transient current signals from switching power supplies, inverters, and motor controllers.
| 3276 | DC to 100 MHz, 30 Arms |
|---|
Use optional power supply 3269 or 3273 to drive the current probe when power from the Memory HiCorder or oscilloscope is not available.
Key Features
• Wide band: DC to 100 MHz (-3 dB)
• High S/N characteristic enables measuring ultra low mA-range current waveforms
• Connects directly to oscilloscope BNC input terminal
• Connects directly to the Memory HiCorder to provide waveform monitoring
• An optional power supply is available for use with oscilloscopes that do not provide probe power
