400 MHz active differential probes with ±2 kV input, high CMRR, and wide attenuation ratios—built for accurate floating, inverter, and power measurement applications..
The PMK Bumblebee Series is an advanced range of active high-voltage differential probes, purpose-built for high-speed, high-voltage applications. With a 400 MHz frequency response and ±2,000 V input capacity, these probes are perfect for measuring switching signals in inverters, motor drives, power converters, and other floating systems.
The Bumblebee Series supports floating measurements, i.e., voltage measurements where the reference point isn't 0V, a common requirement in modern power electronics and high-side gate driver designs. Its ultra-high CMRR performance ensures signal integrity even when large common-mode noise is present.
The probe offers a full spectrum of attenuation settings, ranging from 1:1 to 10,000:1, giving you flexibility to adapt to different signal levels without compromising accuracy.
For operation, a dedicated control box is required, enabling stable power and configuration to match your test environment. With 2-meter cables and robust design, these probes thrive even in harsh or noisy lab setups.
