Combining a novel shielding technique, utilising a low sensitivity coil and patented low-noise signal-conditioning circuitry, the CWT MiniHF wide-band screened probe boosts immunity to local dV/dt transients while maintaining small size, flexibility, and 3 dB bandwidth of up to 30 MHz for a 100 mm coil. The probes feature a coil 4.5 mm thick with 5 kV insulation voltage, and can handle maximum current slope of 100 kA/µsec.
