The 3273 -50 - 3276 CLAMP ON PROBEs only need to be connected directly into the BNC input on waveform observation equipment such as an oscilloscope or a recorder. Then simply clamp onto the conductor to be measured to easily observe current waveforms under a wide bandwidth and high sensitivity conditions. 3273-50 3276 3276 3273-50DC to 50 MHz DC to 100 MHz 3273-50 to 3276 CLAMP ON PROBE

The 3270 is a DC/AC amplifier that can be connected to the 9274/9276 to enable current waveforms to be recorded and easily observed by connecting a recorder or oscilloscope. The high degree of electron mobility in InSb makes it ideal for our highly sensitive thin-film Hall element. We have adapted these qualities for measuring a wide range of current, as well as for very low levels. The probe cannot be used alone: the 3270 is required. 50 Ω 0.1 mΩ or less at 55Hz 0.02 m Ω or less at 55Hz
