High In-Phase Signal Rejection Ratio
High Bandwidth/High Voltage Differential Probe

BumbleBee is a 400MHz, 2kV differential input (1kV in-phase input) compatible differential probe. It is ideal for signal measurement of motor drivers, switching power supplies, inverters, converters, etc. that use power devices such as IGBTs.
With an overload indicator on the input (+, -) and output, the four-stage attenuator and offset function enable optimal measurement.

  • Broadband 400MHz
  • 2kV compatible
  • High CMRR
  • 4-type attenuation(50:1, 100:1, 250:1, 500:1)
  • Can be used with any measurement equipment with 50Ω input
BumbleBee + Accessories

BumbleBee Main Unit and Accessories

Probe Tip Adapter
Held using 2-Footer

Example of holding using an optional twin holder and
3D positioner

By using a probe tip adapter to probe pins soldered directly to the substrate, waveform disorder can be suppressed.

Probe Control Box (sold separately)

* A probe control box is always required when using the main unit.


The main unit is powered and controlled via USB or optional Ethernet. The control software is included with the USB memory in the probe control box.
