Using Rogowski technology, the CWTMini50HF extends the high frequency capability of the CWTMiniHF range to enable measurement of rise-times as fast as 12.5 nano-seconds with a small 100mm, 3.5mm thick coil having a high frequency (-3dB) bandwidth of 50MHz and a peak di/dt capability of 80kA/µs.
This is achieved without sacrificing the probe’s excellent immunity to interference from fast local dV/dt transients.
Initially the CWTMini50HF will be available in peak current ratings of 600A and 1200A and will feature a thin 3.5mm thick coil rated for 2kV peak insulation.
