The CPHX9000A/B series Rohde coil high-frequency current probes are high-frequency current probes for testing AC current signals, featuring high bandwidth and high accuracy (typical value 2%). The probes have communication functions and can be used with the intelligent probe controller OT7001 to control the oscilloscope in real time, setting parameters such as the model of the connected intelligent probe, voltage and current type, attenuation ratio, and delay. This completely solves the long-standing difficulty of users having to manually set probe parameters when using third-party oscilloscope probes, achieving the same user experience as dedicated oscilloscope interface probes. The bandwidth reaches up to 220 MHz, with a withstand voltage of up to 1 kVpk, and a standard BNC output interface, making it convenient to connect to oscilloscopes, data acquisition devices, and other instruments to observe current waveforms. It can be powered by four AA batteries or an external USB DC5V power supply, providing flexible and convenient use. The probe ring and cable length can be customized according to customer requirements to meet special testing scenarios.
