The CPX9000(S/L)A Series Flexible Current Probe is a probe that only tests AC current signals. It features high bandwidth and high precision (typically 2%). The probe has a communication function and can be used in conjunction with the intelligent probe controller OT7001 to realize real-time control of the oscilloscope, setting parameters such as the product model, current, voltage type, attenuation ratio, and delay of the intelligent probe connected by the user. It completely solves the long-standing difficulty where users had to manually set probe parameters when using third-party oscilloscope probes, achieving the same user experience as oscilloscopes with dedicated interface probes.
