1. Summary
CPHX9000A/B series Rogowski coil high-frequency current probe is a high-frequency current probe that designed to measure AC current signals, with characteristics including high bandwidth (up to 220MHz), high voltage withstand value (up to 1kVpk) and high accuracy (typical value of 2%).
With its standard BNC output connector, CPHX9000A/B can adapt oscilloscopes and data collectors of any brand, and observe current waveforms; powered by 4 AA batteries or external USB DC5V power supply brings more flexibility and convenience to use; The length of the probe coil and connecting wire can be customized according to customer’s need to meet special measuring requirements.
