  • Special Features
  • Specification

The PMK BumbleBee® Series is purpose-built for today’s demanding power electronics applications, offering unmatched differential and common-mode performance for signals up to ±2000 V. Each model is equipped with four user-selectable attenuation ranges, enabling users to adapt to varying voltage levels while minimizing noise and maximizing resolution.

With bandwidths up to 500 MHz, these probes are ideal for analyzing fast switching transients, such as those found in GaN, SiC, IGBT, and motor drive systems. The long 7-meter cable ensures signal acquisition from remote or enclosed test environments without compromising signal integrity.

Each probe features manual control via the probe head and optional remote control through a PMK power supply (USB or LAN-enabled). For portable and isolated use, the AP-01 battery pack delivers more than 8 hours of independent probe operation — perfect for mobile or field testing without software requirements.
