Safety Information BumbleBee

BumbleBee has a rated Input Voltage of 2000 V Measurement Category I or 1000 V CAT III.

Note that the max. input voltage rating of the probe decreases as the frequency of the applied
signal increases. (see Voltage Derating on page 9)

See the relevant section of this manual for further information on maximum input voltage, voltage derating and
definitions of relevant IEC Measurement Categories (CAT).

Grounding the Probe

Connect the probe to the oscilloscope input and connect the ground lead to earth ground before performing any
measurements.

BumbleBee is designed for ground-referenced measurements only.

About BumbleBee

BumbleBee® is a 400 MHz, 2 kV Measurement Category I or 1 kV CAT III High-Voltage Differential Probe,
that can be used with every instrument having 50 Ω Input Impedance.
The probe is very effective in power device evaluation such as measurements in IGBT circuits used in the design
of motor drives, switching power supplies and frequency converters. Especially 1700 V IGBT modules for
inverters and converters.
BumbleBee is also very effective in fast transient measurements with bandwidths of up to 400 MHz.

Measurments at GaN and SiC modules as part of new semiconductor techniques prot from that in particular.

It provides a 4 Mode Attenuation, which allows higher resolution measurements. The probe provides overload
indicators for each input channel as well as for the output. That makes it easy to observe, that the differential

probe is working in the specied range.The probe also provides an active offset correction in a range of ± 4 V,

related to the output voltage, with a resolution of 15 Bit.

®

These and many other functions can be remotely controlled with the PC-Software "PMK Probe Control".
The Software is free and included in the scope of delivery of PMKs PS-02 and PS-03 Power Supplies.

The intuitive gracal user interface makes all interactions with BumbleBee clear and easy.

Measurement Princible

The differential probe consists of two attenuators, which are differentially matched. The Voltage measurements

of these attenuators is conducted ground-referenced. The read voltages are provided to a differential amplier,
where the differential voltage is amplied according to the choosen attenuation.

The Output Signal is fed over a driver stage to the 50 Ω Input of a measuring device.
