The Micsig CPXX03B current clamps, with a bandwidth of 50/100/150 MHz, offer excellent value for money. They are therefore a good option if you are looking for an affordable current clamp. Thanks to their standard BNC interface, they are compatible with all oscilloscopes. In addition, they offer accurate and easy-to-use AC/DC measurement functions, a range selection of 5 A / 30 A, an overload indicator and undercurrent detection, as well as 1% DC accuracy.
