Model：Bumblebee Country of Origin：Germany
Category：High-voltage differential probe
Due to the high-frequency switching characteristics of SiC devices and third-generation semiconductor devices such as GaN, the Vge signal requires a high-voltage differential probe with very high precision and wide bandwidth. Bumblebee is currently the most suitable active differential probe in the world for this type of testing.
BumbleBee is a differential probe that supports 400MHz and 2kV differential input (1kV common-mode input). It is ideal for measuring signals of motor drives, switching power supplies, inverters, and converters using power devices such as IGBTs. The input (+, -) and output have overload indicators, and the four-stage attenuator and offset function enable optimal measurement.
BumbleBee body and accessories
| Using the probe tip adapter 2-Footer fixing | Example of maintenance using the optional dual holder and 3D positioner | Probe pins soldered directly to the circuit board |
Powers and controls the main unit via USB or optional Ethernet. The control software is included with the USB memory stick in the probe control box. |
